New Year’s Day
I got on for a bit last night for SKN. I don't know if it was just bad band conditions with the remnants of that CME lingering; or perhaps it was my atrocious bug fist. I made no contacts last night.
During the day today, I did a bit better. I worked five different NPOTA activations (6 QSOs):
N8XX - TR04 - North County National Scenic Trail
W1BXY - NS76 - Weir Farm National Historic Sight
NC8IN - NS55 - Ninety Six National Historic Sight
NR3P - SS01 - Assateague Island National Seashore
KK4ZUU - BP02 - Mnasassas National Battlefield Park
K7UPJ - NS55- Ninety Six National Historic Sight
I just realized now that I worked NS55 twice. Basically, I was dial twiddling, working the ones I could hear decently. There were a few others, but QSB was so bad on 20 Meters at times that I bypassed a few, thinking conditions would get better. They didn't, and going back to try and work those again, I found them to be gone. Sometimes the Propagation Princess is a cruel mistress!
Only N8XX and NR3P were CW, though. I had to break out the microphone and resort to SSB for the others. As Yoda would say, "A disturbing trend in The Force, I sense".
As mentioned in an earlier post, the 2016 NJQRP Skeeter Hunt will be featuring NPOTA - but let that be just a foot note. I would hope that a lot of you who read this blog regularly will step up the plate and activate NPOTA entities using CW (and QRP).
Remember, it doesn't have to be an elaborate set up, with multi ops and crazy antenna installations that last all day. This NPOTA program was tailor made for portable QRP ops! Go to one of the entities, throw a wire into a tree, or perhaps break out the Buddistick, Buddipole, Alex Loop - what have you. Get on the air for a few hours and hand out some contacts!
Also, remember that this is a year long celebration. There were a bumper crop of NPOTA activations on the air today. It seems that everyone wanted to be active on "Day One", but there are 365 days left (this is a Leap Year, don't forget). So get out there and have some fun. That's what this is all about - going outdoors, setting up and having some fun.
This is OUR specialty, guys! Let's show them how it's done!

Stew Perry Topband Challenge
Last night saw another running of the winter Stew Perry Topband Challenge.
This contest is unique in that the usual density of activity on the eastern side of the continent does not necessarily provide an advantage ... contest scores are determined by the distances worked and each QSO will have a different point score, depending on its distance. The exchange is a simple one ... grid locators only ... and from these, the point score for each contact is calculated. From my way of thinking, and many others that I have discussed this with, the 'SP' is one of the fairest contests there is, putting everyone, no matter where they are located, on an even footing.

From here, operating in the 100-watt category, it was a struggle to work the normally easy single-hop stations, with no signs of the central states for several hours after sunset. Several east coast stations were worked towards midnight for the nice 12-point per QSO scores, but truth be told, almost all contacts were a struggle with many stations needing several repeats just to get the call or grid.
My half-sloper antenna and radial system is located right on the edge of the ocean, looking to the east, and its already low takeoff angle is enhanced with ~ 6db of sea (horizon) gain, making it a poor antenna for anything within the first-hop region ... after that it really seems to comes to life.
At 12:15 a.m., I pulled the plug, ending up with just 97 QSO's and 555 claimed points, way down from normal. Other claimed scores can be viewed on the 3830Scores.com website.
My best DX is usually JA but this time was KH6. The SP is always fun, but better conditions would have really made it a blast ... hopefully next year!
Tri-Tet Fun

I spent a few hours yesterday, operating in the 'RAC Winter Contest'.
Originally, this contest began back in 1932, when QST excitedly announced a 'Canada-U.S.A. Contact Contest' to run in mid-January of that year.
The contest turned out to be extremely popular and has been run, in one form or another, ever since ... gradually becoming known as the 'VE-W Contest', sponsored by the Montreal Amateur Radio Club, and eventually by its modern name, with one version in July and a second in December.
As a teen-aged ham, the 'VE-W Contest' was always the highlight of the year as the contest format, much as it is today, made anyone with a 'VE' call as sought-after as AC4YN ... not the one in North Carolina!
Old-timers and DXers will remember the call, as it represented the rarest of all possible contacts at the time and only a very lucky few made contact with the low-powered station, high in the Himalayan mountains at the British mission encampment in Lhasa, Tibet, in the late 30's. Having an 'AC4' QSL on the wall anointed you bragging rights for life.
Another great aspect about the contest back then, as in most, was that stations exchanged real RST's and not the meaningless '599' of today's contest operation. It was always interesting to learn how my little station, nestled in the upstairs attic, was really sounding at the other end.
I decided to set up my homebrew 'Tri-Tet-Ten', 6L6 crystal oscillator, and give the contest a short try. Being unable to conveniently move around the band meant that I would be reliant on stations answering my CQs ... not something that normally happens with the little transmitter in typical contest QRM ... but the magical 'VE' factor would change all of that, I hoped.
I plugged-in the 15/20m plate coil and got out my old homebrew RF-sniffer / wavemeter. It was the first piece of gear that I built, as a new 15 year-old ham, and the poor man's spectrum analyzer has been in constant use ever since. Using the 40m crystal's third harmonic, I have found the wavemeter is the easiest way to avoid mistuning and quickly found myself with just over 5 watts of RF ready to go. A tune-up for 20m later, found the second harmonic producing about 10 watts of pile-up generating madness.
Nowadays, the rules have changed a bit, and 'VE-to-VE' contacts are worth more than 'VE-to-W' QSO's but for 'W's, the goal is still to work as many 'VE's as possible ... and call they did.
Over the period of a few hours, the Tri-tet did not disappoint, generating 206 callers, including PY, PJ and HP ... frequently generating pileups 4 and 5 deep. I didn't try 10m as by the time I got started, it was falling off and the 6L6's 4 1/2 watts of fourth harmonic output on 10m requires really good conditions to be heard very well.
Due to conflicts with other activities, this was the first RAC VE-W Party that I have operated in many years ... it's nice to see that apparently not much has changed since 1932!
Get Ready: Month-long Special Event for SKCC, the 2016 K3Y Celebration
Are you ready for the annual, month-long special event by the Straight Key Century Club (SKCC)? The SKCC Group membership is free, and celebrates the longest tradition of amateur radio: Morse code. But, not just any Morse code. The manual creation of Morse code by “straight” keys means no electronic origin, only mechanical. This is a month-long event, during January 2016, modelled after the ARRL Straight Key Night.
Here’s a video that I made showing my activity as the control operator of the special event station, K3Y/0, during one of the many shifts during January (2015). K3Y is the special event callsign of the Straight Key Century Club (SKCC). The special event operates each January. I’ll be doing this again, this coming month, January of 2016.
K3Y, the Straight Key Century Club’s annual January celebration, commemorates the club’s founding in 2006 following the American Radio Relay League’s Straight Key Night. A small group of participants wanted to extend the fun of SKN throughout the year. The SKCC is the result.
For the first three years, the club’s founders used K1Y, K2A, and K3Y as the celebration’s special-event calls. But someone cleverly noticed that a 3 is nothing more than a backwards, curvaceous E. This “KEY” event has operated under the K3Y call ever since.
The on-air party is open to members and non-members alike. It runs from 0000 UTC Jan. 2 through 2359 UTC Jan. 31. It’s a great time to introduce others to the joys of hand-crafted Morse code using straight keys, bugs, and side swipers.
This year, January 2016, we’ll be fielding K3Y operators in each of the 10 US call areas, plus KH6, KL7 and KP4, along with specially scheduled stations in each of six IARU continental regions. Your QSOs with event operators in all these 19 areas will be tabulated in the Statistics section and can be confirmed with a K3Y QSL card and Sweep Certificate.

’29 BK QSO Party – Night #2
Weekend #2 for the 1929 Bruce Kelley QSO Party found propagation even poorer than the first weekend.
With the 'K' index rising to level 4 along with the arrival of high speed solar winds, it was an uphill battle once again. And as usual, the terrestrial winds were relentless at 60-90km/h here for the entire event ... the worst winds I have experienced during any previous BK's.
The new MOPA did not suffer from the same level of frequency jumping as my previously used Hartley or TNT oscillators but the high winds were still able to cause some melodic pulling of the oscillator. Apparently there is still enough trickle-down coupling from the PA to the oscillator when high winds cause sudden shifts in impedance or resonance of the antenna ... but generally I was much happier with the new BK transmitter.
This year's BK QSO total was the lowest I have had, with just 29 QSO's. A few more were added on Saturday night as well as early Sunday morning, including one QSO on topband.
KK7UV, Steve in Montana, can always be counted on for a clean-sweep and working him on 160m completed that task again this year. Steve's extensive fall antenna work has really payed off as his '29 signal was always impressive up this way. His 160m Hartley signal was a solid 579.
KK7UV - Hull Hartley |
Hats off to Bill, K4JYS in North Carolina, as once again his signal seemed to be the one most consistently heard here, on both 40m and 80m. Bill runs a single-wire off-center fed Hertz at 40', as described in December 1929 QST and it seems to work very well.
K4JYS - 210 Hartley |
George, N3GJ in Pennsylvania was worked along with Larry, W2LB in New York. Larry's 5W Hartley signal was an amazing 559 and solid copy. His breadboard '29 rig is proof that it doesn't have to be pretty to do the job and join the fun!
W2LB - 227 5W Hartley |
Another one of the night's highlights was working Lou, VE3AWA, on 80m, who I had missed the previous weekend. So far, Lou and I have never failed to work each other on 80m but it was looking rather dire until his signal suddenly popped-up shortly before 8PM, keeping our record intact.
VE3AWA - 210 TNT |
These stations were worked on weekend #2 ... Hartley oscillators having the edge once again.

Please do consider putting something together for next year's BK Party as more new activity, particularly from the western side of the continent, is always wonderful to see and adds much more excitement to the party.
You might find the three-part 'Building '29 Style' links on the right sidebar of some interest should you be planning on joining the fun and ... if you are looking for help, you will find many '29 ops willing to do what they can to get you BK-ready on Yahoo's AWAGroup. Everyone would love to work you next year!
’29 BK QSO Party – Night #1
Harold - KB0ROB |
This past Friday night's wonderful propagation during the ARRL 160m CW Contest, pretty much went into the dumper for Saturday night's 1929 Bruce Kelley QSO Party, sponsored by the Antique Wireless Association.
In spite of the auroral-like conditions, with the K-index reaching level '5', the melodic tones from many of the old (and new) clunkers could be heard pounding out their annual 'CQ AWA' invitations.
Among my 19 contacts (8 on 40m and 11 80m), the highlight of the night was working W2ICE/1 in Maine on both 40 and 80m. In reality, this was Paul, N1BUG, operating Bruce Kelley's original 10 watt TNT, which rose to almost S9 levels on 40m, once the sun had set. The Kelley transmitter is moved to various locations each year, a new AWA tradition.
As well, Larry (NE1S), also in Maine, was worked on 40m with his 10W TNT.
A new station for my '29 logbook was George (N3GJ), in Pennsylvania. George was managing 8 watts input to his version of a 1929 TNT.
When I first tuned-in, several years ago, to hear what these 1929 signals sounded like, two of the best sounding signals were coming from KBØROB (Harold), shown at the top, and KBØMM (Burt), both in Minnesota. I could hardly believe they were using era-appropriate rigs as their signals sounded as good as many modern rigs. Thankfully nothing has changed, as these two stations continue to hand out 'MN' using their well-built 'MOPA'-style time machines.
Scott, WA9WFA, the BK score-keeper in charge of logs, faded up briefly with his fine-looking Colpitts.
Here is a list of the '29ers worked so far, along with their rig style and DC power inputs.
40m
KK7UV Hartley 10w MT
W2ICE/1 TNT 10w ME
NE1S TNT 10w ME
VE7BDQ Colpitts 8w BC
K7SF Hartley 10w OR
K4JYS Hartley 10w NC
WB2AWQ Hartley 10w NV
N3GJ TNT 8w PA
80m
KBØMM MOPA 8w MN
KBØROB MOPA 9w MN
W7LNG TNT 7w OR
K4JYS Hartley 10w NC
W2ICE/1 TNT 10w ME
WA9WFA Colpitts 20w MN
KK7UV Hartley 10w MT
W9TFC Hartley 10w WI
N2BE Hartley 10w NJ
KIØDB MOPA 10w MN
WØLGU MOPA 10w MN
As you can see, 'Hartley' construction takes a slight edge. Vintage 'handbooks' and magazine articles from the era, have always promoted the TNT as the best 'beginners' rig but in reality, the Hartley is much easier to build and to get working with a good-sounding signal. The TNT requires some finicky tweaking of the grid coil in order to have an equally stable-sounding note.
I'm happy to report that in spite of the very high winds (as usual), my new MOPA's tone remained virtually unmoving ... for the most part! This was its first real workout and after my first QSO on 80m, my frequency began making large jumps and suddenly sounding very unstable, along with fluctuations in power output. My initial thought was that one of the old original mica caps was starting to breakdown.
After disconnecting one lead of each capacitor (one at a time) and temporarily clipping in a modern substitute, I was no further ahead. I had originally isolated the frequency instability to the amplifier stage and there was only one thing left ... the amplifier's grid-leak resistor. It appeared to be slowly failing, by increasing resistance in jumps. The 12K resistor was now measuring ten times that value and quickly rising. A new 12K, temporarily clipped in place, cured the problem but it had cost me over an hour of operating time ... probably the best prop of the night as by the time I got back on the band, signals were weak and auroral-sounding.
Hopefully the bands will have mended themselves by next Saturday night, allowing some of the smaller eastern stations to make it back to the west coast for some memorable '29 'transcons'.
ARRL 160 CW / ’29 QSO Party
'29 MOPA |
I spent about five hours last night in the ARRL 160 CW contest, working 321 stations in 74 sections. Conditions were excellent, with my 150W sustaining long runs and big pileups. It reminded me very much of the old F2 days on 6m, running huge pileups of JA's. Unfortunately I'll not be able to continue tonight because of the conflict with the '29 QSO Party.
In reality, I may not be in that one either, as right on schedule the winds have picked up once again, with gusts to 83 km/h predicted throughout the day ... I'll be lucky if the power stays on for the QSO Party tonight. As well as doing their best to blow my antennas around and make my already shaky '29 signal sound even worse, these high winds all too often result in long power outages here in the Southern Gulf Islands ... my fingers are crossed, as they are every year at this time.

If I'm lucky enough to still have power, this will be the inauguration of my newly-constructed MOPA '29 rig ... a two-tube, Master Oscillator Power Amplifier. This rig will be much more 'wind-proof' than my previous mainstays, a single-tube TNT or the Hull Hartley. Both of these self-excited oscillators sound overly 'melodic' when directly coupled to an antenna swinging, or more often, blowing like crazy, in the wind.
If you ever wondered what the ham bands may have sounded like back in 1929, have a listen this Saturday as well as next Saturday night. You will hear some amazingly good signals being generated by these '29 state-of-the-art transmitters as well as some pretty awful sounding ones. It was the pretty awful-sounding ones that led to the crackdown for amateur radio in 1929 as hams were forced to clean up their act or suffer the consequences.
Activity will gather around 3550-3580 kHz and 7100-7125 kHz ... the second weekend will see some meet on the very low end of 160m for an hour, probably around 0400z. I hope some of you will be joining the fun as well, with your newly-constructed 'old' rig!
