My 2019 Novice Rig Roundup Summary





Once again the Novice Rig Roundup (NRR) has come and gone ... and once again, it was the most enjoyable 'contest' of the year for me.




What I have come to enjoy most about the NRR is that most participants do not really treat it as a contest but more as an opportunity to spend some relaxing CW time enjoying some of their favorite vintage rigs ... spread out over nine days of activity. Since there was never a Novice-class program in Canada, I was never a Novice, but the NRR brings back all of the good memories experienced as a newly-licenced radio-crazed 15 year old operator!

Back in those times, there was a gratifying sense of achievement with every contact. My clap-trap collection of parts and tin gutter-pipe verticals, mounted atop our old four-story city house, magically sent my tiny signal from coast to coast and over the pole.







Those were the dying days of big-daddy Cycle 19, and my station was proof that just a tiny bit of RF was all that was needed under such amazing solar conditions.






This year's NRR began by making a couple of contacts with my Drake 2NT and VF-1 VFO but my newly-finished 1936-style Jones Push Pull Oscillator was begging to be put to the test. This meant that the remainder of the week would be spent using crystal-control and in all likelihood, sending a hundred or more 'CQ NRR's, hopefully attracting some of the crowd.



Due to previous commitments, I missed a few nights of operating but ended up with 53 NRR contacts in 23 different states or provinces. Operating on 40m in the late afternoon and then for a short period on 80m after dinner, proved to be the best use of my time, as usually, much of the eastern activity had closed shop for the night, just as the band was getting good. There were two nights of superb 80m propagation but with very little NRR activity ... unfortunately for many participants, late-night operating (even with wonderful propagation) is not in the cards for those that must rise early for work the next morning!

There were several highlights for me once again and being able to create them while using my new homebrew rig was very gratifying.

Roger, VA1RST, back in Halifax, Nova Scotia, was one east-coaster that seemingly cherished the midnight-oil! His great Drake 2B ears were able to copy the little 'Jones' on 80m with no problem and his participation added an exotic DX-flavor to the NRR.



Michael, W3TS, managed to squeeze enough RF from his one-tube 6AG7 crystal oscillator to be heard and worked here on both 40 and 80m, with a respectable 559 on 40 and 569 on 80!




It wasn't until after the NRR was over that I realized why Mike's call was familiar as we had worked a couple of times already this winter on the 630m band (475kHz) ...doh!




More transcon magic was made when Tom, K3AJ, finessed a few watts from his single 6CL6 crystal-controlled DX-machine to the west coast on both 80 and 40m. The propagation gods must have been paying close attention as his 40m signal was a solid 579 while his late-night 80m signal was a whopping 589 here ... 80m propagation just like the good old days!




Not to be outdone by Tom, ex-Nebraskan Andy, KØSM in New York, kept his vintage '42' clipped together long enough to be worked back here as well. With just a couple of watts from the early '30s tube, his signal was no problem on both bands.



Gary, W8PU, with his newly-built mid-30s 6L6 tri-tet oscillator, was another treat from the east when his 559 80m signal arrived here from Ohio in good form.



A little closer to home, WB2AWQ, Howie down in Reno, had a whopping signal all week whenever I heard him on 40m. Howie can always be counted upon for 'NV' in most vintage rig operating events, including the 1929 BK Party. This time 'round, he was using his BC-458A, crystal-controlled at 35 watts out. It's a good bet that hundreds of Novices got their start with a surplus Command set such as this, which often sold for just a few dollars in the 50s ... still new in the box!



Even closer was new Oregonian, Dave, WB7WHG, who was still getting set up at his new location on the east side of the Cascades in Bend. Dave keyed his Knight T-60 for our NRR contacts on both 80 and 40 and was very much louder than when I used to work him at his midwest WB9WHG QTH!

The T-60 is a popular choice among NRR ops and it's diminutive size is somewhat misleading as the current-hungry sweep tube used in the PA stage packs a big wallop. If you happen upon one of these under a fleamarket table, don't pass it up ... it"s a lethal NRR weapon!



Heathkit stations were as popular in the NRR as they were in countless Novice shacks decades ago ... and they sound just as good now as they did back then.

KN8RHM (N8XI), Rick, made Michigan proud with his HW-16 transceiver, while Mark, VA7MM, handed out 126 contacts from western Canada with his all Heath vintage station. His newly added homebrew TR switching system provided hands-free break-in, saving wear and tear on the DX-60's precious function switch.




VA7MM wasn't the only west-coaster generating Heathkit RF. Toby, VE7CNF, used this efficient setup. The box under the VF-1 is its power supply, a QSK system plus a magic eye for tuning ... very nifty!



Not many Viking Rangers were heard this year but the one keyed by Markus, VE7CA, sounded very 50s-like with its oscillator being crystal-controlled for the event.



K9SB, Tim, used his Johnson Adventurer and Hallicrafters SX-101A vintage setup as well as a vintage Drake station to hand out 'IL' to many NRR ops.





There seems to be no shortage of era-appropriate Novice gear out there but as the years progress, it will get harder and harder to find and probably more expensive to own. It's wonderful to see so many amateurs that understand and appreciate this older gear and are doing their best to keep it all working ... and the NRR is just one of many opportunities to let these old beauties demonstrate their capabilities.

From what I can tell, NRR activity continues to increase every year and will hopefully be even bigger next year. If you were a participant, don't forget to get your log completed along with your photos and soapbox comments, all of which can be done through the NRR website here. If you enjoyed the NRR, all run by volunteers, consider making a small monetary donation to keep the event going. You can do this via the NRR site as well.

If you're one of the many NRR participants that didn't want the event to end, don't forget that every Monday is the NRN (Novice Rig Night). A short 'CQ NRN' in the usual CW watering-holes, will often provide some nice rag chew time with like-minded operators.

Thanks to all organizers and participants for the CW fun and for another great ride in the NRR time-machine ... see you again next year!

The 2019 Novice Rig Roundup (NRR)


One of the most enjoyable operating events of the year is fast approaching -- the Novice Rig Roundup or 'NRR'. Technically, it is a contest, but I have the feeling that most participants think of it as just a lot of fun and a nice opportunity to hear and work some of the great old 'classics' of the past -- rigs that were used when they were teenage Novices or rigs that they could only drool about owning, back in those formative years when they each discovered the magic of radio.


Once again the bands will be alive with the sounds of Heath AT-1s, DX-20s, DX-35s, DX-40s and DX-60s, Johnson Adventurers, Eico 720s, Drake 2NTs, Knight T-50s and T-60s, Ameco AC-1s and of course, an endless variety of lovingly-constructed homebrew delights and ... a full 9 days to celebrate the 'good old radio days' of their teen years, as many of us remember them.

The dates to remember are 0000 UTC March 2 to 2359 UTC March 10 and this multi-day opportunity is, for me, what makes the NRR so enjoyable. With a nice diversion from the usual 'contest frenzy' associated with standard weekend operating events, the NRR can be enjoyed throughout the week, whenever you choose to participate. If last year's operating patterns continue, you should find activity at any time of the day ... and even more as sunset arrives.

With the fast-approaching solar minimum, we will be hard-pressed to relive the glory days of worldwide 15m propagation, as even last year's event proved to be tough on this band. With a little luck and, hopefully, a well-timed solar flare, we may get lucky! If you operate during the daylight hours, please get on 15m and give it a shot ... and be sure to announce your activity on the NRR's sked and chat page here, so that others will know where to find you, especially if you are rock bound in true Novice fashion. With our present spotty conditions, we need all the help we can get and the sked page proved a very valuable asset during last year's affair.

Although technically not required, if you plan to participate it's best to obtain your own NRR number, which is an easy 30-second process.

Additionally, there is an online logger where participants can post their daily log. The nifty logger also keeps track and figures out your score as it goes and no 'after contest' log needs to be submitted. If you plan on submitting a log, the logger is a requirement. The logger will also require you to set up a 'log-in' and once again, a simple 30-second process will take care of that from here. If you used the logger last year, you will have to set it up again for this year as the old system has been changed.




Stations may run either crystal-control or VFO or can switch between either method ... the online logger will keep track and score things appropriately.


All of the rules and information can be found on the NRR's excellent website. As well, the soapbox comments and station pictures from last year's NRR may provide the inspiration that you need to spark-up your own activity in this year's event ... from what I can tell, this year will be bigger and busier than ever!


There is also a dedicated NRR Yahoo Group, often the source of much valuable discussion but there is a now HUGE group of great NRR chat and activity now on Facebook's NRR Group here. I avoided Facebook for many years and have now discovered that it is an excellent forum for real time chat and information exchange ... one can still choose to maintain a very low profile and avoid unwanted interaction if set up correctly.

In 2017 I ran my homebrew Longfeller in the (now eliminated) QRP category, and had a ton of fun. You can read about it here. Last year, I refurbished a nice Drake 2NT that had been gathering dust in the basement for over 25 years and ran it during the 2018 NRR. You can read about my activity and some of the rigs encountered during last year's fun here.

If you have access to the web while operating, be sure to bookmark and check into the NRR's realtime chat page. Many ops that are crystal controlled will announce their operating frequencies, making it easier for you to find them ... sometimes way up or down from the normal NRR watering holes of ~  3550 - 3650 kHz7100 -7125 kHz, 21.100 - 21.150 MHz and 28.114, 28.120 MHz ... and don't forget to check the colorburst crystal frequency of 3579!

'CQ'ers should always remember to tune up and down the watering hole for replies from other NRR stations that may be crystal controlled and not able to answer you on your own frequency!! This is extremely important and a real reminder of what was common practice back in the Novice days.

Harry's homebrew 6AQ5 crystal oscillator (Feb '55 Popular Electronics) and Hallicrafters S-53, pictured above, allowed him to work the world back in the amazing radio days of Cycle 19. Let's relive some of that excitement in the closing days of Cycle 24 ... in the NRR!


You still have time to get that old clunker on the air but if that's not possible, you can join the fun with your modern rig as well ... all are welcome to jump in and have a great week of radio-fun. I think you will be surprised, just as I was last year, how good some of these old classics can sound ... and you'll hear some great bug-fists as well.

As indicated on the NRR website, this is "more of an EVENT than just a typical contest ... once again taking our OLD ham radios off the shelf and putting them to use again! "

See you in the 2019 NRR!

The 2019 Winter "Classic Exchange"

W7OS - Radio Club of Tacoma working the CX
This winter's running of the CW "Classic Exchange" will take place on Sunday, January 13 and on Tuesday, January 15. The following month will see the Phone "Classic Exchange", on Sunday, February 24 and on Tuesday, February 26.


The "CX" encourages participants to use older vintage gear including any homebrew equipment, both receivers and transmitters. A unique scoring system provides bonus points for various equipment and combinations as well as encouraging 'repeat contacts' when you switch to different equipment.


W8KM and his wonderful vintage station

No vintage gear? ... no problem! All amateurs are invited to participate and get in on the fun no matter what they are using and submit their scores.


K3MD's Heathkit AT-1 and Hallicrafters HT-37 ready for the CX

The CX is a low-key relaxing affair and the 'extra' Tuesday operating period should encourage a lot of midweek activity from the vast numbers of retired operators who cherish and run older gear.


Lots of combos ready at W4BOH's CX setup


























K6ZI, Las Vegas - WWII ARC-5s ready to go

A summary of the Fall 2018 CX and soapbox comments, along with some wonderful vintage-station eye candy, may be found here.

For complete details of the upcoming event, see the web site announcement here.

If you've never entered the Classic Exchange, why not give it a try this year as it truly is a case of 'the more the merrier' ... and eastern operators, make sure to keep the porch light on for those out west!

Hunting Foxes With QRP






For those of us that enjoy CW as well as QRP operating, the Winter QRP Fox Hunt nights make for an exciting combination of both interests.




The QRP Fox Hunt is an operating event during which low power (QRP) stations or "Hounds", attempt to make contact with specific QRP stations designated as "The Fox".

Spanning a twenty week period from November to April, each week sees two Fox Hunt events ... one on Tuesday evening and another on Thursday evening. The Tuesday night event sees the Hounds go hunting on 40m, while on Thursdays, the move to 80m, for an even greater challenge.

For each evening, there are two assigned 'Fox stations', usually one in the east and one in the west. The object of the hunt is for the hounds (you and I) to find and work the fox ... both foxes if you can, as bagging both is the ultimate goal. This all sounds pretty easy except for the fact that all foxes and all hounds are limited to 5W output or less, and therein lies the fun! If you have never heard a pileup of QRP stations, it is worth tuning in just to listen ... a multi-station cacophony of QRP signals, all around 559 or weaker ... it's not your typical kilowatt-laden ear crushing pileup!

The 40m foxes will be found between 7030 and 7050, while the ones on 80m will be between 3550 and 3570 kHz. Most foxes make a habit of working split, usually listening 'up 1', so once you find the pileup, the fox is easier to locate.

The hunts begin at 0200Z and run until 0329Z ... early evening here on the west coast and mid-evening out east.

Complete rules and a 'Fox Hunt Primer' may be found on the QRP Fox Hunt home page here. For discussion of the individual events and soapbox comments, join the QFox ioGroup site here or join the chat in Facebook's QFox QRP Foxhunt Group.

If you're in search of some challenging week-night operating fun, you may just find what you are looking for with the bi-weekly QRP Fox Hunts. Working both foxes is not as easy as it might sound and is an excellent test for your antenna system and of your CW operating skills. Come and join the fun this coming Tuesday ... no special hunting permits required!

Drake 2NT And The Novice Rig Roundup (NRR)


One of this summer's radio workbench projects was to refurbish my Drake 2NT transmitter for this winter's NRR event. The 2NT was introduced in 1966 with the 'novice' ticket-holder in mind, selling for $129. It was the first and only CW-only transmitter produced by R.L. Drake.


As novice transmitters go, the 2NT was a cut above some of the others out there, boasting interesting features such as a built-in antenna changeover relay, sidetone oscillator, grid-block keying and built-in low pass filter.


The tune-up procedure was simplified as well and with Drake's reputation for quality construction, the 2NT became a popular choice for Novices and Generals alike.





My own 2NT was purchased, along with the matching 2C receiver and speaker/Q-multiplier combo over 25 years ago at a Washington state ham fleamarket. Ever since then they have been patiently sitting on the shelf, trying to catch my attention.

The motivation and much-deserved attention finally arrived this year after enjoying last winter's NRR and hearing several great-sounding 2NT's on 80, 40 and 15m CW. I operated the week-long Roundup with my homebrew 'Longfeller' at 5W output, in order to qualify for the QRP category.

6AG7 - 6V6 'Longfeller'
I have to admit, the Novice Rig Roundup, was one of the most enjoyable contests I have entered in many years! Hearing many rigs from the 50's and 60's sounding so good was just a bonus. It was particularly gratifying to be able to work the midweek daytime activity on 15m ... a luxury that we may not enjoy now for several years if most of the long term solar forecasts are correct.

I eventually ended up with 68 contacts, but at 5W, it was a challenge ... most of my many 'CQ NRR' offerings were unanswered, so it was mostly a 'search and pounce' operation. With this in mind, I soon decided that next time, I'll get the 2NT ready to go and hopefully, with a little more oomph, can attract some callers.

Each entrant received an NRR certificate - a nice touch

Rather than hunt down and purchase the individual replacement electrolytics, especially the multi-unit can capacitor which was impossible to source, I ordered the '2NT re-cap kit' from Hayseed Electronics. They supply replacement kits for several boatanchors and are able to make and stuff multi-section can capacitors to match the original size and specs ... and all at affordable prices.

After cleaning the chassis and all of the switches, re-tubing with new tubes and removing / replacing all of the electrolytics, the 2NT was ready to go. Using a crystal for excitation, the following results were obtained:

         80m 103W input 75W output efficiency = 73%
          40m  92W input 65W output efficiency = 71%
          20m  92W input 65W output efficiency = 71%
          15m  92W input 55W output efficiency = 58%
          10m  92W input 50W output efficiency = 54%

Keydown voltages averaged ~520V while plate current ranged from 170-200ma. All-in-all, right on target and not bad for a 51 year old transmitter!

The 6EA8 modified Pierce oscillator in the 2NT seems particularly 'crystal-friendly', as every old style FT-243 style crystal that I tried sounded great. Even the newer ones from AF4K using a modern HC-49 crystal slab mounted inside a vintage FT-243 holder sounded great and worked perfectly.

My newly refurbished 2NT - ready to go

A couple of days later, I returned to the bench to take some blog photos of the rig delivering power into the wattmeter. When I turned the 'stby' switch to 'transmit', the plate current suddenly shot up (with no keying) and the meter on my Variac supply indicated over an amp being drawn by the power transformer ... all with zero output and no crystal plugged-in!

A look at the schematic diagram revealed that with the grid-block keying system, the final amplifier's cathode is always grounded and a low voltage negative bias applied to the grid keeps the plate current cut-off until being keyed ... with cut-off bias missing, plate current will soar, along with transformer primary current. I suspected that something had gone haywire with the bias supply.


A quick check of the 2NT's printed circuit board containing the bias system components among others, indicated a discolored silicon rectifier (D5) in the bias supply. An in-circuit measurement revealed that it was indeed shorted, basically supplying raw AC across the filter capacitor and shorting out the transformer winding, quickly elevating the transformer's temperature in the bargain ... not good.

Although the diode only has to handle a small amount of current, it was mounted with a heat-producing 2W resistor straddling its top surface. As well, the phenolic circuit board was noticeably discoloured from the heat. I suspect this was the main reason that D5 eventually failed.

My 2NT was an early one, serial #670, so perhaps this parts-arrangement was re-engineered in later models. Once the diode was replaced with a much smaller modern one, of twice the rating, everything returned to normal. The last thing I would want to do at this stage is to burn out the transmitter's unique power transformer, undoubtedly impossible to replace nowadays.

The next bench project will be to refurbish and improve the stability of my Heathkit VF-1 VFO and to mate it with the 2NT.

'55 QST VF-1 ad
There are several things that can be done to a stock VF-1 to improve its performance. Its wonderful backlit green dial will bring back a lot of memories from my teenage operating days with the VF-1 ... most, but not all of them, warm and fuzzy.



Another small quirk noticed on my 2NT is the meter mount. My early model has the meter mounted so low that the silk-screened 'PLATE CURRENT MA.' label is not clearly visible when looking straight-on.

My #670
Later models show that this was changed by moving the meter a little higher so that the label can be easily seen without having to look down inside. Nothing major, but something apparently missed during the initial panel design.

Later models
I'll have more to say about the 2018 NRR later, but if it's something that you may be interested in trying and you don't yet have a suitable novice-style rig, it's not too late to start looking, building or refurbishing.

You can read many interesting soapbox comments and see some nice NRR station photos from the previous two events here and here, but read with caution as you could easily get hooked. I find pages like this very inspiring and they remind me of the days when QST would publish photos, soapbox comments and exacting equipment descriptions used by each section winner in the annual November Sweepstakes contest.

Winner's gear in '55 CW SS - remember these?
NRR activity really skyrocketed last winter and I expect that it will be an even busier event next time. There are several CW contests that I'm looking forward to this winter and the NRR is right near the top of the list. I hope to see many of you in the 2018 NRR!

My Favorite Contest



A few blogs back, I briefly touched upon my favorite contest of the year ... the 160m Stew Perry Contest, or more affectionately noted as the 'Stew' or 'SP'.



The contest is named in honor of W1BB, one of the earliest and most dedicated proponents of 160m in its earlier days, as well as being the first amateur to earn 160m DXCC #1, in 1976.

courtesy: http://www.k1zm.com/w1bb
Stew published a regular '160m News' bulletin, lovingly cranked out on his old Gestetner (remember those messy things?), which was mailed free of charge upon request.

These bulletins were chalk-full of DX reports, station information, and antenna-building hints. It was hard not to get excited about the Topband after reading one of Stew's bulletins!


This was largely back in the day when very few commercial transmitters had a 160m position on the bandswitch. If it did, it was most likely a hernia-making DX-100 or a similar E.F. Johnson biggy ... seems most 160m ops were he-men back in the early days.

Heathkit DX-100
To make things even messier, the band was covered with horrendous Loran QRM, much more devastating then anything the Russian 'Woodpeckers' could throw at us ... working anyone on 160, let alone DXCC, was a challenge and probably the main reason why so many found the band fascinating.

The 'Stew' is just a short 24 hour affair but often packs the CW band from end to end with a ton of activity, including lots of DX. It seems that most 160m diehards will jump at any opportunity to get on their favorite band, especially when conditions are as good as they have been of late.

The 'SP' is somewhat unique in that its system of scoring is probably the fairest of any contest around. The number of points earned for any QSO is determined by the distance between the two stations, with your computer contesting software dutifully making the needed calculations automatically from the exchange of Grid Square information, rather than the ubiquitous  '599'.

Such a system gives stations in the western half of North America a chance to compete, on equal grounds, with the much higher activity levels found back east. With most contests awarding fixed points per QSO, it is much easier for eastern stations to rack-up big scores by working the multitude of other easterners ... this is just not possible out west where activity levels, and population densities, are so much smaller.

Contest PR-man ... Lew, W7EW, on behalf of the Boring (Oregon) Amateur Radio Club sponsorship, has sent a heads-up via the Topband reflector, which is reproduced below in case you wish to learn more.

Greetings Radio Ruffians with a TopBand Bent,
The anticipation is palpable as time draws near for the
start of the 21st Running of The Stew Perry TopBand DX

out as some prior plaque proposals were too obtuse, couldn't be performed
by any one of our species or just a tad obscene.
There will be one or two more postings of the categories and sponsors
right up until and through the start of The Stew so don't delay! Also those
who haven't sent off their check or PayPals for their plaque sponsorship yet should not delay either.

Also follow Stalwart's VK6VZ's example and go fire up your system
tonight so you won't be modally morose when the only thing that happens
when you call CQ is that you open and close the neighbor's garage door
with a distinctive cadence.

73 and I remain,

If you have a few hours of free time this Saturday night, why not give the 'Stew' a look, especially if you've never operated on the Topband. If you can load-up that old longwire on 160, I'll guarantee you'll have fun as well as be surprised at what you can work ... hopefully I'll see many of you this weekend in the best contest of the year!

ARRL 160 / 630m DX

courtesy: http://www.arrl.org/

This weekend's ARRL 160m CW was a ton of fun.

Conditions were unusually good, which always makes things more interesting.




I ended up with 412 contacts in 78 out of 83 ARRL sections. If I was attempting a WAS on Topband, I would have made it to 48, missing just Nebraska and Rhode Island. Oddly enough, RI was my 50th state when I completed my original 160m WAS, back in 1984, which was certificate #225.

That was done from my tiny 33' wide suburban lot, using the same antenna that I have now, a half-sloper. My radials were strung around all four edges of the property line and just lay on the ground or were stapled to the fenceposts. The power came from a pair of 6146's and was just a little less than I used in the contest this weekend as I entered in the Low Power (150W) category ... however, back then it took me several winters to finish my Topband WAS as there was a lot less activity than there is nowadays it seems. The only other sections missed during the contest were Puerto Rico, Newfoundland and North New York.

With a fairly dormant Sun and the 'almost-quiet' geomagnetic conditions of late, good propagation continued into the week ... in fact, Sunday night was the best I have ever observed on 630m!

Such stable conditions here on the west coast always favor the east-west and polar paths and Sunday proved that in spades. Overall, 53 different stations reported reception of my 630m signal, more than any previous overnight period.

The highlight however, was the reception of my signal in Europe, with five decodes from LA2XPA on Kalvoya  Island off the southwest coast of Norway. Rolf has an exceptional location and nice beverage antennas so most of the heavy-lifting was being done on his end. However, without the co-operation of the propagation gods, none of this would be possible. To make things even better, John, VE7BDQ, also made it across to Norway as his small station continues to perform amazingly well. As I mentioned in an e-mail earlier today, his is the textbook example of what can be done on 630m with a small suburban backyard, some homebrewing skills and a small antenna system.

The WSPRnet map shown here illustrates just how many folks are tuning in every night to this part of the spectrum ... with many getting instantly hooked. Hopefully this great propagation is just a small taste of what lies ahead for us over the next several years of low solar activity.

Mailbox, Coffee And The 'Stew'




Recent mail has brought two nice surprises. As I am preparing for this weekend's ARRL 160m CW affair, a certificate from the ARRL arrived ... from last year's 160m CW Contest!






It seemed that I had somehow stumbled into top score from VE7 land for the single-op, low power division and since I haven't seen a QST in decades, this came as a complete surprise.


Over the years I've always tried to test the 160m waters at contest time just in case conditions are amazingly good ... which they haven't particularly been for the past few years of solar angst. Even piddly Cycle 24, for most of its lifespan, has proven powerful enough to mess up the Topband.

The 160 contest I enjoy the most is the December Stew Perry. It's the only one that's scored fairly and QSO points are determined by distance. Compared to working something close, any of the east coast grids from out west will get you a sack-load of points ... anything off continent earns you a boat-load. My strategy in the Stew has always been to 'search & pounce' the FN and FM grids for their high value point reward. If I had more late-night staying power in any of these affairs I could probably do a better job but I've found my fondness for the warm fleece-sheeted bed beckoning earlier each year. I'm sure it has nothing to do with getting older ... right?

I honestly don't know how some guys, much older than myself, can hang in there 'til dawn. Maybe it's coffee, which would certainly do it for me. If I even look at a coffee after the noon hour, I'm still counting sheep past midnight. A late night contest-coffee for me would guarantee no sleep until the following night unfortunately.

The second surprise was a nice QSL from Mark, WA9ETW in Wisconsin, confirming our recent crossband QSO ... 630m to 80m CW. Notice Mark's receiving antenna used on 630m, just a 100' wire about 15' off the ground! It doesn't take much to hear domestic signals on 630m so if you already have the WSPR software installed and are familiar with its operation, why not set your receiver to 474.200 in USB mode and see what you can hear. There are stations from coast to coast beaconing every night on this band. Be sure to set your software to upload your decodes to the WSPRnet site so that everyone, especially the beacon operators, can see who you are hearing.

If we worked in the recent 630m crossband event and you'd like a card, please let me know ... I'll be happy to put one in the mail for you.



How I do wish that the FCC would get on with it and legalize the 630m band in the U.S.A. Hopefully the turnovers in Washington will not translate into further delays as is often the case when big governmental changes are in the works. In the meantime, hopefully we can at least work each other in the ARRL CW 160 this weekend!

CQ 160m CW Weekend




This past weekend's CQ 160m CW Contest saw the normally quiet band bursting to life with signals stacked up, one atop the other, from 1800 -1870 kHz.


At times it was very difficult to find a clear frequency to send 'CQ' and much of the contest was spent in the 'search and pounce' (S&P) mode. When a clear frequency was found I was able to have several short runs but running for any length of time while in the low power category is not realistic. I think my best hourly rate peaked at '60' for a short time as propagation would improve momentarily ... often, ten or more CQ's would go unanswered and then the next one would have two or three responses, continuing on for several minutes until the propagation would shift. These sudden 'holes' in the D-layer absorption seem to occur when conditions are marginal and it's as if the propagation switch is suddenly thrown from 'poor' to 'really good' for a few short minutes.

Overall, conditions from western B.C. were poor on Friday night and much improved on Saturday night. Although several DX stations were heard and called on Friday night, none were worked. These same stations came right back when called, on Saturday evening.

My 160m antenna is very simple, consisting of a 'half-sloper' and about fifty in-ground radials. Since the tower and antenna are mounted right at the ocean's edge, this year I threw two extra radials into the ocean ... whether or not these made any difference is difficult to say but they certainly wouldn't make things worse.


Because of the proximity to the ocean and the half-sloper producing vertical polarization, my antenna always seems to favor stations at the ends of the single-hop F2 distance ... those along the east coast and into the Caribbean as opposed to mid-continent signals. I often find myself sending several repeats to stations in the central states while those on the far coast will reply on the first call ... even stations that I can barely copy, will often come right back, which seems puzzling.

Overall, about 10 hours were spent in the contest ... ending up with 223 contacts in 51 sections and 9 DX entities. Some of the DX stations worked were PJ2, HK1, ZF2, C6, KP2 and 4V1. Checking my 160m DXCC list after the contest, I was surprised to see that 4V1TL in Haiti was a new country for me, making the contest time well worth it. Claimed scores for this, and any contest, can be viewed on the 3830 Scores website.

As the solar cycle continues to decline, 160m conditions should only get better and better, with the next few years hopefully producing a few Europeans in the 160m log once again.
