I recently heard that the DX Doubler (DXD) SO2R Controller by TopTen Devices, has been discontinued. Looking at their Web Site, it has completely vanished, along with the Radio-specific cables, User Manuals, etc. This controller was a great addition to my shack a few years ago. It is a very simple design, with no Microprocessors... Continue Reading →
DXDUSB Next Version with Custom PC Board – UPDATED
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 – DX Doubler USB Interface Update
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 →
VA QSO Party 2016 – Two for the Road
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 →
It Really is all About Antennas
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 →
USB For DX Doubler First Prototype
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 →

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...

2014 ARRL Sweepsatakes – Much Fun but no Sweeps
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...

ARRL Sweepstakes CW (SSCW) 2014
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 →
November Sweepstakes: Is this the year?
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 →
