Here Comes The Spring 'BR' (Bug Roundup)



The upcoming ‘BR’ will be upon us shortly (more details later), but the pending activity brought back some of my early ‘bug memories’ and the good times as a young ham.


I first learned CW in Boy Scouts at age 12 and was pretty excited since I had been shortwave listening by then for about three years ... finally I was going to know what all those dots and dashes I had been hearing were all about!


Unfortunately, to no fault of our well-meaning Scoutmaster, we all learned it the wrong way ... from ‘flashcards’. This made the learning curve a lot harder but in a few months I was copying code off the air and discovering the exciting new world of amateur radio.

By the time I was old enough to legally get my licence (age 15), I could comfortably copy 40wpm and had no trouble with the required 13wpm test.

Having taken the test day off school for the exam and to travel to downtown Vancouver on the bus, there was nobody in the city happier than me when I walked out of the almost five hour exam as ‘VE7ANP’!

Back then, in ‘63, the exam consisted of five parts and a ‘pass’ was required for all of them or you were sent packing for 30 days. The CW receiving test required 100% copy at 13wpm, with the same speed for the sending test. I think it was for three minutes. Next was a multiple choice test on regulations that consisted of about 50 questions. The fourth section required the (unaided) drawing, in schematic form, of a crystal controlled two-stage transmitter, a simple superhetrodyne receiver, an A.M. modulator, a full-wave power supply, some form of over- modulation indicator and a key-click-filter. The final section was an oral exam, as the examiner made you explain your circuit drawings while he probed with questions that were designed to trip up innocent kids that had foolishly ventured downtown.                                                                                                                                                                
There were two radio inspectors in the office back then, but getting one of them in particular, was the equivalent of drawing the proverbial short-straw ... ‘old man Baxter’.

He was a giant of a man, standing well over six feet tall, suspender-laden with a jowly face and saggy pants ... along with the growl of a drill sergeant. I quickly realized that I may have been better off staying in school that morning, as OM Baxter was sitting behind the desk, waiting for me, when I shakily opened the door marked ‘RADIO EXAMINATIONS’.

As it turned out, the OM loved CW and when I breezed through the CW tests with no glitches and speed to spare, his rough edges vanished as he seemed to warm up to me. I learned later that almost all prospective examinees failed the CW test miserably on their first go and were given a 30 day time-out ... it seemed that my Boy Scout days were paying-off in spite of the numerous mid-winter rain-soaked Scouting equivalents of the Bataan Death March, that put me off of camping for the rest of my life.

For the first several months on the air, I used my venerable old brass handkey that I was very comfortable with. I only wish that my hand-sent CW was as good today as it was back then ... something I should really work on again. Although I could send at a fairly good clip, it wasn’t long before I was working a lot of guys that were sending even faster, with their bugs. Back then, electronic keyers were just starting to dribble onto the scene and most CW diehards were using a Vibroplex, and boy did they sound great!

One of the popular radio-joints of the era was ‘R-P’ (Rendell-Parret Electronics) on 4th Avenue, started by Hedley Rendell, VE7XW and Bill Parett, VE7AM, who lived above the store. For many years on Tuesday nights, Hedley hosted the Vancouver Amateur Radio Club’s ‘Code and Theory’ class in his basement rec-room. The class was taught by a very kind and gifted teacher, Al Erdman, VE7AQW, the radio engineer for local AM powerhouse, CJOR, in Vancouver. Over the years, between Al and Hedley, dozens of new hams realized their dreams thanks to their their weekly commitment for which I will be forever grateful.

Now Saturday mornings at ‘R-P’ was a ‘whose-who’ of local hams, all dropping by to see what gear had popped-up in the trade-in section of the store, usually adorned with various Hallicrafters, Hammarlunds or Collins rigs ... stuff I could never afford but could at least touch and turn the dials before they found new homes. There were usually a few guys from the, ‘by invitation only’, Vancouver DX Club. To their credit, most were gracious enough to treat a new 16 year-old ham like one of their own and it didn’t take them long to convince me that I really should get a ‘bug’ if I was going to climb the DX-ladder and get into the pileups ... hmmm, pileups with my DX-20?

It seemed clear that a bug was in my future and the most affordable for a 16 year old was this one coming from Japan.





Although they were all likely manufactured in the same factory, the ‘BK-100’ was sold throughout North America under several different names. Back then, most of the affordable radio toys in Vancouver were coming from Japan ... and for a 16 year old radio nut, their stuff was a lot cheaper to buy than anything from the states.

RP imported a pile of these nice inexpensive BK-100s so I doled out some of my hard-earned cash to get my foot precariously planted on the DX-ladder’s bottom rung. I soon became fairly adept with it and after putting up a full size 40m groundplane on the roof of my parent’s very high house, I was actually able to work Don, W9WNV, at one of his exotics South Pacific stops ... with the bug ... in a pileup ... with the DX-20!




Eventually I had enough saved to buy a real Vibroplex, costing twice as much as the BK-100 ... which unfortunately saw very little use thereafter.

For the upcoming 'BR', I’ve decided to use the BK-100 along with my crystal-controlled 20 watt 'RK-39' power oscillator on both 80 and 40m, but in the  meantime  I’ll be practicing as much as possible on 7050 with the bug.





Here are all the details for the spring 'BR':


The Samuel F. Morse Amateur Radio Club, a Sacramento, California based CW enthusiast club wanted a special time to bring bug operators together on the air. In the same spirit as ARRL's Straight Key Night, participants are encouraged to make simple, conversational, “chewing-the-fat”, "Rag Chew" QSOs using their bug type key. This is an opportunity to exercise, share and exhibit your personalized fist. This is NOT a contest. Simply Call "CQ BR" so folks know you are a Bug Roundup Participant. Grab that bug, clean those contacts, and let’er fly! Let’s hear that “Banana Boat / Lake Erie Swing" or that commercial KPH/WCC quality fist.

Reserve the day! Friday May 15th - Sunday May 17th, 2020
5 PM  PDST (LOCAL) Friday - 5 PM PDST Sunday or May 16-18 UTC (0000 - 0000 UTC)
 

For more information, to register your station and key for participation, and to help assist in spotting, potentially increasing QSOs, an On-line chat window link can be found near the bottom of Bug Roundup home page located at https://w6sfm.com/bug-roundup/ We hope to hear you all on the air!


It looks like a fun event and might make another good opportunity to spark-up your old boatanchor on CW once again. As well, it seems you can keep track of activity and possibly set up skeds via their chat-window page during the BR. I'll be watching for you with my BK-100!

Hunting For NDBs In CLE255



It's another CLE weekend!

During these stressful times, the CLE might hopefully provide some peaceful relief for you.




'CLE's are 'Co-ordinated Listening Events, and NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

This time the hunting ground is the 15kHz slice from 385.0 - 399.9 kHz. kHz

A good target for this one is little 'OO' (391kHz) in Oshawa, Ontario, shown above. 'OO-391' has a measured output of just over 7 watts yet is heard consistently all over North America including the west coast as well as in Europe! Hearing 'OO' is a very good test for your receiving system!

Listen for 'OO's' upper sideband on 391.402kHz with your receiver in the CW mode.

From CLE coordinator Brian Keyte (G3SIA), comes the following CLE info:

Hello all,

Have you tried one of our Co-ordinated Listening Events yet?
Whether short logs or long ones, making them is enjoyed by
beginners and experts alike - and reading them is enjoyed by all.

Our 255th Coordinated Listening Event starts this Friday.  We
should have plenty of NDBs to find in this 15 kHz frequency range.
Even the Pacific region (Oceania) is quite well supplied this time.

     Days:    Friday 24 April - Monday 27 April 2020
     Times:   Start and end at midday your LOCAL time
     Range:   385 - 399.9 kHz

Please log all the NDBs that you can identify with nominal (listed)
frequencies in the range - it includes 385 kHz, but not 400 kHz
 - plus any UNIDs that you come across there.

Send your final log to the List (no attachments please and ideally
in a plain text email) with 'FINAL CLE255' in its title (important).

Show on each line:
    #   The Date (e.g.  '2020-04-24', etc.,  or just '24' )
    #   The Time in UTC (the day changes at 00:00 UTC).
    #   kHz  - the nominal published frequency, if known.
    #   The Call Ident.

Please show those main items FIRST.  Other optional details
such as Location and Distance go LATER in the same line.
As always, of course, tell us your own location and give brief
details of the equipment that you were using during the Event.

We will send the usual 'Any More Logs?' email at about
19:00 UTC on Tuesday so you can check that your log has
been found OK.
Do make sure that your log has arrived on the List by
08:00 UTC on Wednesday 29 April at the very latest.
We hope to complete making the combined results within
a day or two.

You can find full details about current and past CLEs from the
CLE page http://www.ndblist.info/cle.htm   It includes access
to the CLE255 seeklists for your part of the World, prepared
from all the previous loggings in Rxx.

Good listening
- enjoy the CLE and take care.

------------------------------------------------------------------

  (If you would like to listen remotely you could use any one remote
  receiver for your loggings, stating its location and owner and with
  their permission if required.  A remote listener may NOT also use
  another receiver, local or remote, to make 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.


The NDB List 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 NDB List member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

Remember - 'First-time' logs are always VERY welcome!

Reports may be sent to the NDB List Group or e-mailed to CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above. If you are a member of the group, all final results will also be e-mailed and posted there.

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!

World Amateur Radio Day 630m Activity!

 
 
 
 
 
 
The IARU has designated April 18 UTC as "World Amateur Radio Day". 
 
Radio Amateurs of Canada (RAC) is participating with a special event. 
 
 
 
 
 
 
There will also be two 630m stations operating! Both will use the call VE7RAC, one on JT-9 (VE7VV) and one on CW (VA7MM). 
 
The operation schedule is:
 
 JT-9 transmit on about 475.2 kHz: 0300 to 0600 hours and 1100 to 1300 hours UTC
 
CW transmit on 473 kHz and receive 473 kHz plus cross band 3528 kHz and 7028 kHz: 0300 to 0600 hours UTC.
 
If you have been interested in 630m but can't transmit on the band, then PLEASE try and work VE7RAC via crossband. This means that you can call VE7RAC (who will be CQing on 630m) on either 80 or 40m CW and he will respond if he hears you. Working crossband can actually be great fun!
 
RAC will provide a certificate for stations working either of the VE7RAC stations.

LED Lights In The Shack

The following blog was originally published in 2016 but is still relevant today.

Utilitech Pro Soft White LED Bulb

A recent posting by Phil, KO6BB, to Yahoo Group's ndblist, described his recent search for some LED lamps to replace the CFL's in his shack / radio workbench area. If you have been wondering how much RFI that LED lamps might be producing, you may find Phil's findings of some value.








"Recap  

I had a 60W equivalent CFL in the floor lamp directly over my operating position. I'd tried a 100W equiv one but it was extremely noisy! Also a couple CFLs in the ceiling lamp.

This is a floor lamp with a crookneck at the top and a triangular metal
shade reminiscent of the old style desk lamps, bulb is horiz to the
floor. I've used it for years and like it because it places the light
directly over the operating position work area (keyboard, radios etc).
The actual bulb was about 4.5 inches from the front of the Softrock SDR
receiver (in a plastic case), with the base of the lamp (where the
electronics are) about 7.5 inches (somebody asked about the distances).

This coupled a LOT of RFI directly into the SDR, visible on the
waterfall. For best results when recording and having the light on I'd
slip a 60W incandescent lamp in place of the CFL. The lamp is also
about 16 inches above the operating table, and when listening to ANY
portable radio on the table, if it was in the AM or Longwave band and
using the built in loopstick antenna, got a LOT of RFI from the lamp
(unless the lamp was off ;-)

So today I went down to Lowes (we have a Costco, but I don't have a
card) and looked at their LED lamp offerings. As I expected they had a
large variety of them, from a low cost 3 pack for ~$9.00 for 60W units
to about $18.00 or so each (Sylvania). From what I read here I wanted
to avoid the REALLY cheap ones as some reported them to be 'noisy'.
Also, I wanted to put a 75W equivalent unit in the one over the
operating position, and a pair of 100W equivalent units in the ceiling
lamp. All three had CFLs, and if I walked around the radio room with a
portable radio and the ceiling lamp on I could hear it's 'hash' anywhere
in the room. . .

The ones I settled on were a brand I'd never heard of, "UtiliTech Pro"
soft white, 75W for the bench and 2 100W ones for the ceiling. They
were what I'd call "mid-priced", $8.98 for the 75W and $9.98 for the
100W ones.

Specs:

75 W one draws 12W and gives 1100 Lumens.
100W one draws 16.5W and gives 1600 Lumens (the pair in the ceiling
should then be 3200 Lumens if I calculated right).

How low is the RFI to my Radios?

75W one over the bench:
NO trace from the lamp electronics visible in the SDR waterfall at
all. With a portable radio on the bench-top, NO audible RFI. Put a
portable radio up to the "bulb" part (light area) and with no station
tuned in can't hear ANY RFI. Move the portable to the base area of the
lamps there is SOME RFI, but I won't be putting the radio that close to
the lamp, move it a couple inches away and the noise disappears.

100W ones in the ceiling lamp, NO audible RFI in the portable when
walking around the room, RFI just barely perceptible right next to the
light wall switch that turns the lamp on, again, audible IF I put the
radio right up to the base of the lamps, not a likely real-world scenario!

Upshot? 

Based on the sample of three that I bought and the almost
non-existent RFI from them I'd consider the UtiliTech Pro lamps to be a
good product and suitable for use in the radio room. I consider them
good value for the ~$30.00 I spent for three."

If you have tested anything similar (other brands / models), please let me know and I will add it to Phil's helpful information.

KO6BB's website can be found here, along with some of his homebrew equipment.

Hunting For NDBs In CLE254




Once again it's a CLE weekend.

During these stressful times, the CLE might hopefully provide some peaceful relief for you.






'CLE's are 'Co-ordinated Listening Events, and NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

This time the hunting ground is the 20 slice from 400.0 - 419.9 kHz. kHz

A good target for this one is MOG (404kHz) in Montague, California, up near the border with Oregon. It gets out very well and has been logged from Finland to Hawaii. Its been on-and-off of late so maybe you can catch it while it's on again!

Listen for MOG's upper sideband on 405.027kHz with your receiver in the CW mode.

From CLE coordinator Brian Keyte (G3SIA), comes the following CLE info:

Hello all,

Our 254th Coordinated Listening Event starts on Friday.
This frequency range is not packed with signals for any of us, but if conditions are OK there should be some nice surprises.

Do join in, whether you have days to spare, or only an hour or so over the weekend.  Staying at home seems to be essential advice for most of us at present - this could be a great way of spending time there!

    Days:    Friday 27 March - Monday 30 March 2020
    Times:   Start and end at midday your LOCAL time
             (Many of us will be changing our home clocks this weekend -
               however UTC time continues unaffected)
    Range:   400 - 419.9 kHz

Please log all the NDBs that you can identify with nominal (listed) frequencies in the range - it includes 400 kHz, but not 420 kHz - plus any UNIDs that you come across there.

Send your final log to the List (no attachments please and ideally in a plain text email) with ‘FINAL CLE254’ in its title.

Show on each line:
    #   The Date (e.g.  '2020-03-27', etc.,  or just '27' )
    #   The Time in UTC (the day changes at 00:00 UTC).
    #   kHz  - the nominal published frequency, if known.
    #   The Call Ident.
