July 2019

I moved to Penrose Colorado in the middle of April 2019 to build my new 80 acre cattle ranch. Currently, the ranch is under construction and with the exception of a dual band 2/70 HT, I'm off-the-air until I'm able to put the antennas up (hopefully very soon). Check out my Rebel Ranch web site for information on the cattle ranch. I'll update this page as things change.

I'm active in the following radio activities and modes:

  • ARRL and W5YI Volunteer Examiner.
  • Former ARRL Official Observer (while living in several different states) untill the program ended.
  • Former ARRL North Dakota Official Observer Coordinator until the program ended.
  • 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.
  • 2 m, 70 cm and .23 cm: AM, SSB, FM simplex and repeaters.
  • HAM satellites: FM and SSB.
  • APRS. I turn my APRS on from time to time, but not as much as I used to.
  • Fox hunting (hidden transmitters).
  • U.S.A.F. Military Auxiliary Radio System (MARS)
  • On 11 January 2019, I've been in MARS for 45 years!

    Current Billets:

    AF MARS 8th Communications Wing Commander (CO, MT, ND, SD, UT, WY - renamed from Region 8 due to MARS restructuring)
    83rd Communications Group Commander (Renamed from ND State MARS Director due to MARS restructuring)

    I've also held and performed duties in the following AF MARS Billets:

    Military Support Network Manager, 2011 - 2019 (name changed from Mission Support Network).

    The NW Division consisted of two AF MARS Regions: 8 (CO, MT, ND, SD, WY, UT,) and 10 (AK, ID, OR, WA).
    Due to AF MARS restructuring in 2015, the Divisions were deleted, but the Regions remain unchanged.

  • 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 (my station is 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 for additional information, or to join.
  • WSPRnet (Weak Signal Propagation Reporter network) running 5 watts, or less. Visit their web site for additional information, or to join. WSPR is featured in the November 2010 issue of QST.
