Hunting For NDBs In CLE 229

YPM - 274 courtesy: VE3GOP

This coming weekend will see another monthly CLE challenge. The hunting grounds will be the 50 kHz swath from 270 - 319.9 kHz, with much of this is being shared by DGPS signals here in North America.



The last time this range was covered was in CLE 212, back in October 2016. Conditions were particularly disturbed back then, as described in my CLE 216 Results blog at the time. Propagation should be much better this time, I hope!

For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

A nice challenge in this one is to hear the Pikangikum (ON) NDB, 'YPM', on 274 kHz. Although just a 25-watter, thanks to its large vertical, YPM is well-heard throughout North America. Will you log it as well?
Look for 'YPM's upper-sideband CW identifier, repeated every 10.5 seconds, on 274.352 kHz with your receiver in the CW mode.

If you are interested in building a system for the new (U.S.) 630m band, the CLE will give you the chance to test out your MF receiving capabilities and compare against what others in your area might be hearing. You will soon know how well your system is hearing.

When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.

For example, 'AA' in Fargo transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz. Its USB tone is actually 1025 Hz while its LSB tone is 1054 Hz.

Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

Canadian NDBs normally have an USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

Here are the final details from CLE organizer Brian Keyte, G3SIA:

Hello all

Our 229th co-ordinated listening event is this weekend, covering a 50 kHz
frequency range - about three times wider than usual.

Days: Friday 23 February - Monday 26 February
Times: Start and end at midday, your LOCAL time
Range: 270.0 - 319.9 kHz
Targets: NDBs (NOT the DGPS beacons)

We can expect very good propagation, but in part of the frequency range
it might be quite a challenge to tease out the NDB signals from among
the DGPS ones.
Any first-time CLE logs will be very welcome, as always.

Please log the normal NDBs you can identify that are listed in the range
(it includes 270 kHz but not 320 kHz).
Please send your CLE log to NDB List, if possible as a plain text email
and not in an attachment, with 'CLE229 FINAL' at the start of its title.
Show on EVERY line of your log:

# The Date (e.g. '2018-02-23' or just '23', etc.)
# UTC (the day changes at 00:00 UTC).
# kHz - the beacon's nominal published frequency if you know it.
# The Call Ident.

Those main items can be in any order within themselves, but BEFORE any
other optional details (Location, Distance, etc.) later in the same line.

As always, give details in your log of your own location and the receiver,
aerial(s), etc. that you were using.
If you send any interim logs, be sure to send a FINAL (complete) one.

You can find anything else to help you, including seeklists for your part
of the World, from the CLE page, http://www.ndblist.info/cle.htm

Joachim or I will send the usual 'Any More Logs?' email at about 18:00 UTC
on Tuesday so that you can check that your CLE log has been found OK.
Do make sure that your log has arrived at the very latest by 09:00 UTC
next Wednesday, 28th February.
We are hoping to make all the combined results on that day.

Enjoy your listening
Brian

(Reminder: You could use any one remote receiver for your loggings,
stating its location and owner - with their permission if required.
A remote listener may NOT also use another receiver, whether local
or remote, to obtain further loggings for the same CLE).

These listening events serve several purposes. They:

• determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date

• determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range

• will indicate the state of propagation conditions at the various participant locations

• will give you an indication of how well your LF/MF receiving system is working

• give participants a fun yet challenging activity to keep their listening skills honed

Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted there a few days after the event. If you are a member of the ndblist Group, results will also be e-mailed and posted there.

The very active Yahoo ndblist Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.

You need not be an ndblist member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

'First-time' logs are always VERY welcome!

Reports may be sent to the ndblist or e-mailed to either myself or CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above.

Please ... give the CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.

Have fun and good hunting!

The 2018 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.

WN4HQW's '62 Novice station (now N4CF)

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 3  - 2359 UTC March 11  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.






Stations may run either crystal-control or VFO or can switch between either method ... the online logger will keep track and score things appropriately. Stations running in both Novice 1 and Novice 2 categories (probably most common), will be eligible for prizes in both modes if they make at least ten contacts using a Novice 1 station or if they work ten Novice 1 category stations.




 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.

Last year I ran my homebrew Longfeller in the (now eliminated) QRP category, and had a ton of fun. You can read about it here. This year, I have refurbished a nice Drake 2NT that had been gathering dust in the basement for over 25 years ... it's all ready to go now, but a problem with the VF-1 VFO has arisen. The combination works well on 40m and above but on 80 it's a different story. The VFO runs on 160m and it seems that the 2NT balks at the idea of doubling in the buffer stage to 80m. Unless I solve the problem, I'll be rockbound on 3579, 3550 or 3560kc. ... it was 'kilocycles' back then, which always seemed to make more sense to me than 'kilohertz'.

If you have access to the web while operating, be sure to bookmark and check-in to 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 kHz,  7100 -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!

Of course with the large number of rockbound stations (on crystals), be sure to look above and below these frequencies. It's good practice to listen well above and below your own frequency as well, for anyone answering your CQ who may be up or down the band on crystal control. Unlike today, this was very 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 2018 NRR!

FCC's Noise Floor 'Study'?

It seems like the FCC's recent interest in doing an in depth study of the growing RF spectrum noise floor has taken a new twist.



The FCC's apparent lack of real action in gathering the data needed to make serious inroads into RF noise pollution has drawn the attention of the ARRL, which voiced their concerns in a recent ARRL Letter as well as in their formal response to the FCC.

In response to the FCC's Public Notice (ET Docket No. 17-340) Spectrum Management proposals, the ARRL "took the opportunity to strongly urge the FCC to reinstate a 2016 TAC noise floor study, which, ARRL asserted, apparently was terminated before it even got started." It would seem that the proposed in-depth study never even happened and the term 'noise' has morphed into an 'interference' issue!

The FCC's paper proposed a number of guiding 'principles' in going forward with spectrum management policies, loosely based on the concept that more emphasis on eliminating 'interference' should be placed on receivers along with continued development of transmitter spectral purity and that with increased spectrum crowding, users will simply have to expect and accept certain, as yet unspecified, levels of interference!

It sounds suspiciously as if the FCC has decided that the source of any noise / interference problems have become too large to control and have passed the buck to equipment manufacturers in order to solve the growing problem for users!

“Indeed, it is difficult to imagine how the Commission can now…suggest the adoption of specific spectrum management principles, incorporating such concepts as receiver immunity, HCTs [harm claim thresholds], and interference temperature determinations without having…a firm grasp on ambient noise levels in basic RF environments and geographical areas,” the League told the FCC.

In their series of guiding principles relating to 'interference realities', the FCC has issued a number of broad, somewhat ambiguous statements, that might be interpreted in any number of odd ways ...

"Principle #1 -- Harmful interference is affected by the characteristics of both a transmitting service and a nearby receiving service in frequency, space or time;

Principle #2 – All [radio] services should plan for non-harmful interference from signals that are nearby in frequency, space or time, both now and for any changes that occur in the future;

Principle #3 – Even under ideal conditions, the electromagnetic environment is unpredictable. Operators should expect and plan for occasional service degradation or interruption. The Commission should not base its rules on exceptional events;

Principle #4 – Receivers are responsible for mitigating interference outside their assigned channels;

Principle #5 – Systems are expected to use techniques at all layers of the stack to mitigate degradation from interference;

Principle #6 – Transmitters are responsible for minimizing the amount of their transmitted energy that appears outside their assigned frequencies and licensed areas;

Principle #7 – Services under FCC jurisdiction are expected to disclose the relevant standards, guidelines and operating characteristics of their systems to the Commission if they expect protection from harmful interference;"

The ARRL response argued that:

“Requiring better performance from receivers or RF-susceptible devices is a valid, reasonable, and long overdue requirement,” ARRL said, “but the major goal of doing so should be to prevent instances of interference ..."

Specifically they argue that amateurs are unique users and able to recognize harmful interference beyond their control and should not be subjected to the same restrictions (ie. get ready to accept new levels of yet undefined interference levels) as commercial users.

"ARRL argued, however, that the Amateur Service should not be subject to receiver immunity standards, because licensees employ a wide range of propagation, emissions, bandwidths, power levels, receivers, and antennas, making any receiver performance standards arbitrary and compromising the Service’s experimental nature. They also are able to differentiate between interference from nearby spurious or out-of-band signals and that caused by receiver deficiencies. The HCT concept does not fit the Amateur Service particularly well, either, the League said; any interference hams suffer from each other is resolved cooperatively. Brute-force overload also occurs occasionally but is resolved by licensees without FCC intervention."

The ARRL seems somewhat forgetful when it comes to several long-standing complaints of inappropriate amateur-generated interference and bad behaviours which have been ignored for far too long ... problems well beyond 'cooperative resolution' by affected amateurs.

Although the ARRL does agree with many of the FCC's proposals, they doggedly insist that the FCC's apparent quashing of their original noise data investigations is critical to going forward:

“That, in ARRL’s view, is a big mistake,” the League contended. “No system of spectrum management incorporating [harm claim thresholds] and receiver immunity levels can be accurately implemented” without the noise study data.

“That study is more important now than ever before,” ARRL concluded, “and it is increasingly urgent as a prerequisite for any new spectrum management policies.”

With Washington's drastic cutbacks in FCC field-office investigators and overall budget trimming, it seems that the FCC is still relentlessly driven to eradicate all forms of illegal (pirate) broadcasting. It's a pity that they don't display the same zeal for dealing with the illegal imports and distribution of the offshore equipment that is quickly killing our ability to hear anything on the ham bands ... without selling-off and moving to several acres in the country.
