Ham Member Lookups: 6643


Hi Folks,

I've been enjoying this great hobby since I was first licensed in high school as KA7HGY in 1980. Before becoming a ham, I was an avid MW & SW listener as a kid and still enjoy logging long-distance AM broadcast stations on winter evenings. My Elmer was Jim Kennedy, W7MID (SK), who was also my high school electronics teacher. He gave me my novice exam and I had a station setup before my ticket even arrived - a Heathkit DX-40 transmitter & Comanche receiver. I was active a couple years but eventually other teenage activities take precidence as we all know!

By early 1990, I was back on the air as KB7FZC then finally as KG7RS around 1992. Obtained Amateur Extra in 1994 - on a bet with a buddy who was going for his 20WPM exam. Thanks to lots of QRP CW, it was a breeze.

I'm very active in Portable Ops and frequently QRV from some remote desert site or mountaintop with an FT-817ND and MFJ-1661 portable vertical antenna. In addition to QRP, I also enjoy homebrewing, operating vintage/antique equipment and SKCC ops, especially in the old novice segment of 40 meters around 7.114 Mhz.

Also trying to attain DXCC after over 30 years (some DX'er eh!)

My home QTH antenna is a Tarheel Model 40A "screwdriver" mobile antenna ground mounted with 30 untuned radials. 8.5' whip for 15-40 meters or 4.5' whip for 10/12 meters. DC power for the antenna motor is conveyed through the RF coax using a pair of MFJ bias T's. Motor control is through a homebrew up/down switchbox which features an LED to indicate motor stall (end of travel). This is an excellent performing stealth antenna and a pleasure to use.

NEW! February 27, 2016 NPOTA Operation from Organ Pipe Cactus National Monument (MN-58)

Portable station at Organ Pipe Cactus National Monument Arizona for National Parks on the Air 2-27-2016. Yaesu FT-817ND, K5OOR HF Packer Amplifer, 12A/hr Lithium Iron Phosphate battery pack. Station was setup at the picnic area adjecent to the Kris Eggle Visitor Center at the Monument. 136 QSO's were made during the 3-hour operation from among 38 states & 3 Canadian provinces. Heavy pileups at times! This was a very enjoyable operation and my thanks to all for the QSO's.

MFJ-1661 portable vertical antenna used at the 2-27-2016 National Parks on the Air operation from MN-58, Organ Pipe Cactus National Monument Arizona.


Home QTH Station: Yaesu FT-450D & Oak Hills Research OHR-100A QRP transceiver for 40 Meter CW with OHR Digital Dial & WM-2 QRP wattmeter. Tokyo Hy-Power HL-50B for use with the OHR-100A when condx warrant. Separate Astron RS-20A power supplies for the FT-450D & HL-50B. Sony external speaker. Homebrew screwdriver antenna controller with motor stall indicator LED. Straight Key is an original E.F. Johnson Speed-X.


Vintage Station with Heathkit HW-16 & HG-10B VFO Circa 1970. 50 Watts on 40 & 15 Meters. This old rig had not been used in over 35 years and was lots of fun to resurrect including new electrolytic capacitors, troubleshooting & replacement of a blown driver coil and lots of clean-up to return it to the air. It performs surprisingly well and is a pleasure on the air.
