The South Plainfield Amateur Radio Club ran a station for the ARRL Rookie Roundup today. While we ourselves were ineligible to operate, we did put out an invitation to all the newly licensed Technicians from our Fall and Winter classes to come out and get their feet wet in HF. The idea, of course, was to show them that there's a whole other world out there in Amateur Radio beyond what they hear on VHF/UHF.

Club member Dave KD2FSI, who qualifies as a Rookie by time, volunteered to set up the station. I say Dave qualifies as a Rookie by time, because by the rules of the contest, he does - he was licensed less than three years ago. However, he is certainly not a Rookie by experience. He has already upgraded to General and is a very busy Ham, diving headfirst into many different facets of the hobby, portable operations being one of his favorite. I wish I could take credit for steering him in that direction, but Dave discovered that joy on his own, without my help.


We had agreed to meet at Putnam Park in town at Noon, in order to set up for the 2:00 PM start. By the time I got there, Dave already had things quite well in hand.

Marv K2VHW and Drew W2OU served with distinction in the coaching perspective. Marv is quite the instructor. He has a gift and a natural talent for teaching and was able to make our Rookies feel like Old Pros in no time.


Here's a picture of Marv explaining to Mario the ins and outs of making a SSB Contest QSO. Mario made his very first HF QSO today, and the process was amazing to watch. The first few QSOs were halting and tentative, but due to Marv's excellent guidance, Mario was having a blast within short order.


Within a short amount of time, our Rookies were able to handle QSO and logging chores while we stood in the background as control operators for NJ2SP.

The opportunity seemed golden. HF operating under portable ops conditions. With QRPTTF next weekend, how could I not bring the QRP gear along? It's always good to perform a test run, no?

I bungeed my 31' Jackite pole to a nearby post and set up the EARCHI antenna as a sloper.In between my stints as an HF coach, I went to town working stations on 20, 17, 15 and 10 Meters. A lot of the contacts were MM contest QSOs, but there was one ragchew in there, also. I worked

9A7R
ZW8T
OX3XR
CO8EH
WD4MSM - ragchew
KP2F
TM9B
EG8TRV - Special Event Station
HA8VK

Not bad for the time I had, in between helping with QSO procedures, serving as a helping set of ears, and talking with some of our other newly licensed Techs about equipment, making recommendations, etc.

The Rookies had a blast as well. 10 Meters was open to Texas and the West Coast and our newbies were amazed that "talking to a guy in Idaho" was as easy as talking to a guy on the local 2 Meter repeater - and that the guy in Idaho sounded better than the guy on the 2 Meter repeater!

In all it was a fun day. I'm not sure who had more fun - our new Techs in getting their feet wet in HF, or us veterans watching their fun and excitement. It was definitely rewarding, and I hope we pushed some people a little more deeper into this fine hobby.

Today I adjusted the turns ratio on my 8.976kHz VLF QRSS3 and 10wpm CW 5W beacon to better match my earth electrodes. At this QTH they look much greater than 50 ohms, which I measured at the “old” QTH and optimised for.

On the way I managed to blow up a TDA2003 IC, which I had to replace. The whole exercise was far more exhausting than I was expecting. It seems that after about 10-15 minutes of physical or mental effort I am done in. Before my cerebellum brain bleed everything today would have been trivial. Now trivial tasks feel like climbing mountains! Although I can see progress in my recovery there is still a long way to go. One of my aims (among many) is to be able to resume field tests as before, but time will tell if I am really up to this: it is quite hard when your brain is still foggy a lot of the time. Oddly, when sitting down at home or when driving things are fine. It is when I do something requiring real physical or mental effort that I get tired. I guess the radio work today was hard as I had not done this sort of thing for some time.

Anyway, the good news is that I hope to do a VLF field test tomorrow.  Everything is ready and tested. It will not be until late afternoon as both my wife and I are busy before then. The XYL will be there at the test site if I get really tired.  Setting up the gear will be especially tiring in my current state. The test site is not too far from home. I have soak tested the TX and it should be fine on QRSS3 using my loop and Spectran at the RX end. I shall report results tomorrow. This will be my first VLF field test in over 18 months. How I have looked forward to this. If the loop is successful I may try the E-field probe.

These days, with dirt cheap kits from China often with free airmail, it is sometimes a wonder that any USA or UK kit companies exit at all. One of these I have mentioned before is Hendrick Kits, which always has a good selection on their website. These are best value if you live in the USA. Several kits are shown as “retired” which I guess means they did not sell well or they had problems with reproducibility. One favourite is the derivative of the BitX SSB design from Ashlan Farhan in India. This uses easily obtainable parts and has been a well proven design. Hendricks sell versions for 20m or 17m.

See http://www.qrpkits.com/bitx20a.html .

It looks like they have just moved so there might we a little delay until early May.

The power out, around 10W, should ensure plenty of contacts. These 2 bands are usually good even when the sun is quiet, so make a good choice. You have to choose either 20m or 17m SSB. I am sure Western kit companies would really value our business. “Use it or lose it”, is a phrase often used about bands. In this case it apples to amateur radio kit suppliers. If we don’t buy from them they will close their doors and cease trading. I am as guilty as anyone having recently bought a 40m Pixie kit from China.

From the Hendricks Kit website:

“The BitX20A and BitX17A are complete SSB kits with board, all parts, digital display and custom powder coated and punched case that is based on the BitX20 that was designed by Ashlan Farhan. The original version was built ugly construction, and you had to source all the parts. I discovered the BitX20 site on Yahoo in 2007, and decided that the BitX20 would be a neat kit for Hendricks QRP Kits. The problem was that it did not have a pcb. A team of Dan Tayloe, Jim Kortge and Arv Evans have worked countless hours making sure that the pcb version was stable and would meet United States F.C.C. Specs. We had to go through several revisions to get it right, and we are happy with the result, even though it took a long time. Some things just take time. The kit includes a commercial quality plated through, silkscreened, solder masked board, and all board mounted parts, plus the polyvaricon tuning capacitor, digital dial, custom powder coated and punched case, knobs and controls. Everything you need to build the kit is provided.
I encourage you to check out the BitX20 users group on Yahoo. They have agreed to provide support for the kits. There are hundreds of messages on there about the history and development of this kit. Our kit puts out about 10 watts, features dual IRF510’s as finals in a push-pull arrangement. The schematic is available at the Bitx20 site on Yahoo. Cost of the kit is $180.00 plus shipping and handling.“

The BitX looks a nice, useful radio. For a beginner it is just about all you need to get started.

If you've wondered why the bands have been so volatile of late, it's because Cycle 24 just won't go away quietly. It seems that for the past several months, our planet has been besieged by one solar bombardment after another. Most of it seems to be coming via Coronal Hole Streams.

This UV image from NASA's Solar Dynamics Observatory satellite clearly shows the large coronal hole presently facing earth. The arrowed vectors represent material spewing from the hole, with much of it earth-bound. The material from this hole is expected to arrive between April 21-22, possibly causing more auroral activity.

Our Sun's latest rotation is showing several new large sunspot groupings, all very capable of unleashing a new round of solar flares and associated disruption ... if nothing else, Cycle 24 is persistent!

Peeks at the geomagnetic activity for April 16th illustrate just how active things have been of late ... making the high HF bands sound like the middle of the night as well as making LF and MW propagation depressing.

The software gurus at NOAA have been busy once again, this time revamping several of their visual models to an 'animated' mode. The Ovation Auroral map is particularly interesting when run in this mode as it shows the auroral field's activity visually over the past 24 hours. The display gives one a new appreciation for the dynamics of such large scale events:

An auroral event on Thursday evening gave 6m conditions a bit of a kick in the backside on Friday afternoon with signals from southern South America making it into various regions of the U.S. including the PNW, usually left out of such affairs. At one point, CE2AWW was hearing / working both the west coast (W7's) and the east coast (VO1's). Sporadic-e was definitely involved on the west coast end as the band was open to California / Nevada for most of the day.

No one can be certain of what lies ahead for Cycle 24 but it's certainly not going away with a whimper!

Having an EchoIRLP node here at home allows me the option of communicating with the XYL (who holds a Tech license) when I am on the road. I found this very useful when I was stationed in Korea. With the time difference, the end of my day was the beginning of hers. I could check APRS to see when she started her morning commute and then connect to my home node. This allowed me to check in with her as well as saying “Hi” to the kids.

With the Summer Trip, the XYL will not be with us the whole time. Therefore, IRLP may well offer a solution.

Time change will not be a significant factor – which means the best times to schedule IRLP QSOs with the XYL would be during the commute times. That should work fairly well because I do not plan to be on the road either too early in the morning or much past the late afternoon.

What is the availability of IRLP nodes along the route I am taking and will they be near our overnight stops? Enter the ARRL’s Repeater Directory. I remember my dad almost always having the shirt-pocket version of this directory by his easy chair along with his HT and a mechanical pencil that he used to make notes. I have consistently followed his lead, although I usually keep a copy in my truck as I am not too much of an HT guy. Another difference is my excitement about the Desktop Edition of the Repeater Directory. I find the shirt pocket edition way too tiny and difficult to use. The Desktop Edition is the Business Class of directories…. spacious, roomy, and comfortable.

I took advantage of ARRL’s birthday coupon to purchase the 2015-2016 directory and am using that to start my IRLP node research. Without digging up my maps and looking too much at the surrounding areas, here is what I found:

Sioux Falls, SD, IRLP Node #7346, 444.2, 82.5
Gillette, WY, IRLP Node #3307, 449.75, 123
Cody, WY, IRLP Node #7194, 146.85, 103.5
Great Falls, MT, IRLP #7908, 147.3
Great Falls, MT, IRLP #5670, 147.36, 100
Bozeman, MT, IRLP #3692, 448.35, 100
Billings, MT, IRLP #3398, 449.75, 100

What I will probably do is use my home node to connect to these nodes to see if they are in operation and get an idea as to what their coverage areas are.
