I have had a number of automatic Antenna Tuners in recent years.I have had MFJ tuners, LDG tuners and the built-in tuners in my TS-930s, Elecraft K2, ICOM IC-7600, and Yaesu FTDX-3000. They have all worked pretty well. The first LDG tuner, the IT-1100 has been a real survivor. I put it in my mobile... Continue Reading →
Using N1MM+ OTRSP Data for Antenna Switching – 2020 Update
I have been looking at antenna switches for using two radios with a number of antennas. The common switches I have found are referred to as "Six packs" or 2X6 antenna switches, which establish connections for 2 radios to any of 6 antennas. N1MM+ provides antenna selection information in a serial data stream via the... Continue Reading →
DXDUSB Update – Now Available
I have completed all the development I plan to do on the DXDUSB interface which allows using any USB Port to interface to a DX Doubler SO2R controller. I now have a stable version and will make available DXDUSB units to anyone that wants them. With the end-of-life announcement of the DX Doubler, I do... Continue Reading →
R.I.P DX Doubler (Updated 8 Aug 2018)
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 →
MFJ-1924 Mobile Screwdriver Antenna Controller Settings
I have been using an MFJ-1924 Controller on my HiQ 4/80 mobile antenna for a number of years. The Controller started having an issue when it was very cold outside (very cold here in VA is < 30 F.). It seemed like an intermittent connection, causing me to fail to get pulse counts from the... Continue Reading →
Raspberry PI 3
I am getting a chance to do some embedded programming with the latest Raspberry PI micro computer and a 7" touchscreen display. The pair can be purchased locally (at Frys electronics here on the West Coast) for under $ 150. If you do some online shopping, you can probably get closer to $ 100. I... Continue Reading →
WINDOWS 10 – More Garbage you Can’t Live Without
I just got a new laptop computer. Had little choice, as the old one is 5-6 years old and it has gotten to the point that it takes several minutes to bootup. I tried all the normal cleanup tricks, but that along with all the major components being badly outdated, made the choice an easy... Continue Reading →
New Blog Look – Comments??
Happy New Year I went to a new layout Theme for this blog in the past couple days. The idea was to allow more articles on the Front Page at once, so you can easily scroll around and pick something, then expand it if you are interested. Also, this new Theme has more capability for... Continue Reading →
Rig Expert Antenna Analyzer
Got a new Antenna Analyzer to use in my continuing attempts to improve the antenna situation at KG3V. I have had a great run with my old MFJ analyzer but I needed to get something that could save measurements to a PC. I got a Rig Expert Unit that covers up to 230 MHz. Here... Continue Reading →
CQWW CW 2016 – A Contest and a Beverage
As I have become more interested in Contesting, I have met some top contest operators in my Local Contest Club, and have been looking for some antenna improvements for my modest Station at KG3V in White Stone, VA. My current antennas include an 80m half-wave dipole on all Bands (with an external Tuner), and a... Continue Reading →
