Life member: ARRL, RSO and others
Member: Central Dakota Amateur Radio Club
Past member of many Ham radio clubs across the USA and around the world, including the JARL while stationed in Japan.
I've held every elected and appointed office in many of these clubs, including the office of President of the Radio Society of Okinawa (RSO) several times during my 6 years there. I'm also the founding President of several Amateur Radio (HAM) clubs in the United States.

  • ARRL and W5YI Volunteer Examiner.
  • HF 160 - 6 meters: CW, AM, SSB and FM. Fixed, Mobile and Portable.
  • Various digital modes on 160 - 6 meters and sometimes on VHF and above.

    Webmaster for this web site, the afmars-msn.org and afmars.us web sites.

    We are looking for new AF MARS members. Contact me for information and click on the MARS menu tab for an application.

  • SHARES SHAred RESources Net Control Station. SHARES is a high frequency (HF) program, administered by the Department of Homeland Security's (DHS) National Coordinating Center for Communications (NCC), allowing certain agencies access to various government radio frequencies and networks. This allows them to pass traffic during times of emergency and when other means of communications are down, or unavailable.
  • HAM and MARS ALE (Automatic Link Establishment).
  • PropNet. You can sometimes find me on PSK-31 on 10/17/30 meters as a PropNET automatically controlled digital station (only operational when I'm in the shack). That means that I'm transmitting 4-6 times per hour and listening for other PropNET stations, but will respond to a QSO request if I'm not doing something else in the shack. We are doing propagation studies. Go to propnet.org for additional information, or to join.
  • WSPRnet (Weak Signal Propagation Reporter network) running 5 watts, or less. Visit their web site wsprnet.org for additional information, or to join. WSPR is featured in the November 2010 issue of QST.

    Due to my move to Bismarck North Dakota (beginning of October 2015), most of my antennas are still packed in boxes, or on the ground. I planned to install the tower and the rest of my antennas during the summer of 2016, but other projects like insulating the walls and building an insulated floor in the shack (loft of the barn), power company installing 200 amp electric service in the barn (meter separate from the house), wiring the shack (4 240 v outlets with more planned, 28 120 v outlets with more planned - never have enough outlets), installing the heater/AC and a lot more took priority. Separating from the house power reduced my line noise from S9 - 20 dB over, to almost nothing! The radio noise level is so quite now (most of the time), I have to check to see if the coax is still attached and the antenna is still in the air.

    Since I was unable to plant my tower and install the rest of my antennas in 2016, the plan was to do it during the summer of 2017. Well, I had both of my knees replaced (right in May and left in August), so between surgeries and recovery time, the summer was wasted for antenna work and fishing. Hopefully I'll get everything in the air this summer (2018) AND, go fishing!

    Summer 2018 looks like it might be a bust for putting up my tower and the rest of my antennas. I had surgery on my left foot on 4 May 2018 and I'm not allowed to put weight on it for 5 weeks, then gradually increase the weight on it over the next two months (three total). When that is healed, I'll need surgery on my right foot (if the doctor allows it this year), but it shouldn't be as bad (hopefully). Darn! Another summer wasted for antenna work and I still can't go fishin'!

    There just isn't enough time, or money to get everything done, that I want to do. And, due to my disability, I'll need assistance installing the tower(s) and antennas. I have 60 feet of Rohn 25G (had 100 feet, but someone made me an offer on 40 feet that I could not turn down) and I can't decide if I want to have one 60 footer, or two 30 footers (there would be a ten foot pipe sticking out of the top making it 70 feet, or 40 feet). I would like a tower close to, or next to the shack for V/UHF (shorter coax for less line loss) and a tower a short distance away from the shack (50 to 100 feet) to prevent RFI to the computers and other equipment.

    Antennas currently in the air:

  • Tennadyne TD-SS120, 120 foot long stainless steel 160-10 meter Broadband Folded Dipole. The feed point is about 35 feet and each end at approximately 11 feet, with the wires running NE/SW. This antenna works very well, but I would like to get it higher in the air.

    My Tennadyne TD-160HP1000 160 foot long, 160-10 meter Broadband Folded suffered hail hail damage to the BALUN, which let rain water inside. Due to the water, the BALUN fried. This antenna was replaced by the TD-SS120. When the BALUN is replaced, it will be put back into the air.

  • Comet 144, 440 MHz and 1.2 GHz vertical at 20 feet.
  • Being forced to retire due to physical disability (2014); money is now on the short side, so it will take much longer than I planned to install my tower and the rest of the HF, VHF and UHF antennas. My Hy-Gain TH-6DX HF beam antenna is so old; it's falling apart and needs to be replaced. I acquired the equipment I have over many years and no, I don't want to sell anything. It would cost too much to replace and I use everything for my MARS and SHARES participation (operate multiple frequencies simultaneously - or will again, when I get the rest of the antennas in the air).

    This web site shall be updated as things change.
