A Diary of Technology Pursuits
After using some DXDUSB prototypes with DX Doubler SO2R boxes for several months, I finally got around to completing the PC Board layout for the next version. This one will add some power conditioning and choice of operation from +5 or +12 VDC. It also should be able to survive use in a Mobile environment... Continue Reading →
DXDUSB Development Status I have had some requests to provide DXDUSB prototypes to couple people. The latest prototype (Protot3) is still very rough. I have a couple in ongoing testing and they seem to be working well. However, these are very rough - assembly is hand soldered wires attached to the Arduino board. While I... Continue Reading →
I went mobile again for the 2016 Virginia QSO Party, using the callsign KT4KA. I use that callsign so as not to confuse everyone when calling CQ (with my normal "3"call). The goal this year was to beat last year, and hopefully win the Mobile all-Band category. No matter what happens, this is always enjoyable.... Continue Reading →
As I try to continually improve my Station, I keep coming back to the antennas. I have a couple very nice Radios, but I am still not very competitive in Contests, especially DX contests. I have always used mainly wire antennas and generally if I can hear them, I can work them. Now I know... Continue Reading →
I recently completed testing of the first prototype of the USB interface for DX Doubler using N1MM+ software. This was a rough prototype, so it isn't pretty but it does seem to work fine. It currently handles RX and TX Focus, and STEREO for listening to both radios at once. There is an FTDI chip-based... Continue Reading →
I have the opportunity this year, for the first time, to sponsor an award plaque for the 2015 VA QSO Party. The plaque I will be sponsoring is for the Single Operator Station that works the most VA Counties and Cities. This award is available to any station. I am especially happy to sponsor this...

I enjoyed working the ARRL Sweepstakes again this year. I operated in both CW and Phone this year. My major effort was in CW, where I managed a personal high score, finally breaking the 100K point barrier. For several years I have been wishing I was involved with a Club that could use my scores...

Here we go again. Time for ARRL Sweepstakes CW (SSCW) 2014. Same plan as always - main objective is to get a personal high score. Secondary objective is to get that elusive "clean sweep" - all US and Canada Sections in one weekend. I have been within 1 or 2 sections the last several years,... Continue Reading →
I have been operating in the ARRL CW November Sweepstakes for several years. It is the ultimate contest - long exchange, many stations active, and a fast pace. If you like contesting, there are many enjoyable contests, but this one is special in my book. One thing that continues to elude me in ARRL CWSS... Continue Reading →
Well I kept up the time-honored tradition of missing 1 or 2 Sections in the CW SS contest this year. Had about 575 QSOs (a personal best) and all but 2 Sections - MB and NNY. I never had trouble with a New York section before. I guess the monster storm Sandy may have been... Continue Reading →
