Life member ARRL, RSO and others. Past member of many Ham radio clubs in 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've also been the founding President of several Amateur Radio (HAM) clubs in the United States.

Please QSL via eQSL.cc. My card is "Authenticity Guaranteed"
(AG), which means they have a copy of my HAM license on file.
I'm active in the following radio activities:
HF and 6 meters: CW, AM, USB, LSB and FM. Fixed, Mobile and Portable.
Various digital modes (mostly PSK-31) on 160 - 6 meters and sometimes on VHF and above.
2 m and 70 cm: AM and SSB with very little FM repeater or simplex activity.
.23 cm: AM, FM and SSB.
HAM satellites: FM and SSB.
APRS. I turn my APRS on from time to time, but not as much as I used to.
U.S.A.F. Military Auxiliary Radio System (MARS). National Mission Support Network Manager and Master Net Control Station (NCS) on both Voice and Digital nets. Prior to accepting the National Network Manager position, I was the South West Area MARS Region 9 (NV, CA and AZ) Voice Net Manager and Public Information Officer.
We are looking for new members. Contact me for information, or click on the MARS menu tab for an application.
SHARES – SHAred RESources Net Control Station. SHARES allows government agencies access to various radio frequencies and networks which allows them to pass emergency traffic.
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. That means that I am 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. Visit their web site http://wsprnet.org for additional information, or to join. WSPR is featured in the November 2010 issue of QST.
ARRL and W5YI Volunteer Examiner.
ARRL volunteer for other HAM radio related activities and services.

Fldigi software for most HAM and MARS digital modes. I have several others on the computer, but Fldigi seems to work the best. M110A DMT software for MARS MIL-STD 110A digital. HF Antennas: Other Antennas: Butternut HF9V Ground mounted 80-6 meter 9 band vertical. The feed point is 24 inches above the ground with 24 radials and 100 feet of coax. Additional ground radials will be added as time and finances permit.
20 meter vertical dipole sloping to the North East.
B&W BWDS-90N 160-10 meters Broadband Folded Dipole 90 feet overall configured as a semi-inverted V, hanging on the end of a wooden dowel 3 feet away from the side of a 30 foot Rohn 25G tower at the 29 foot level with the North end at 20 feet and the South end at 14 feet.
End-fed, 245 foot long wire ten feet above the ground. Slight problem with this antenna - It's four feet directly above a six foot chain link fence and only seems to work on 80 meters and close by MARS frequencies with excellent results. However, it tunes very well with a roller inductor tuner on the higher bands, but seems to attenuate both receive signals and transmit power.
80 meter dipole currently configured as a horizontal/sloping V, open to the South. The feed point is at 23 feet on the tower which is low, but due to other antennas in the way, it's a high as I can go for now. The end of the East leg is at 12 feet and the West leg is at 14 feet which can't be lowered due to a 13'6" clearance requirement as it goes over the driveway. This antenna works very well as a general coverage receiving antenna below 30 meters and on the higher harmonics. It also worked very well with a tuner on 40 meters and most of the MARS frequencies I tried. I was really surprised that it receives especially well on the VLF frequencies down to 30 KHz which is as low as my receiver will tune. I have never heard much of anything down that low and never WWVB on 60 KHz until I installed this antenna! There are some really interesting signals down there.
60 meter NVIS dipole. The feed point is 15 feet above the ground with the North end at 20 feet and the South end at 10 feet.
20 meter beam. A home brew 20 meter, three element mono-band yagi will be constructed soon and mounted on a 10 foot mast between 32 to 35 feet on the 30 foot tower.
Wire antennas for additional amateur bands, MARS and SHARES frequencies will be constructed soon. Tri-band vertical on 2m, 70cm and 23cm.
It's either a Diamond or Comet, but I forgot which.
Currently at about 15 feet, but will be mounted on the tower at about 40 feet.
Satellite antennas: M2 Egg-beaters. EB-44 on 2 m and EB-432 on 70 cm.
Both at 15 feet above the ground with about 50 feet horizontal separation.
Six meter Ringo Ranger vertical.
Will be mounted at 20 feet on two tower sections in the North East corner of the property.
10 element dual band 2 m and 70 cm beam horizontally polarized. Will be mounted on the tower at about 38 feet
