Greeting from S. Central Washington State!
I enjoy Ham Radio, particularly aspects of antenna performance and radio wave propagation (a science and an art.) Rarely pass-up a Rag-chew via any mode. Background includes HF-UHF communications op, analyst and/or consultant for the USAF & Joint military operations. Also twisted wrenches to service and repair flight/power control systems on jet fighter aircraft, specifically the F-15 A-D.
CURRENT ANTENNAS:
HF:
10m vertical, 5/8th (MAX 2000) Tweaked the coil and added GP elements for 10, 12 & 15 meters. Antenna is roof mounted @ 38' with a fiberglass mast to reduce noise. Good to excellent performance on 10-15m.
80M OFFSET-DIPOLE (WINDOM, Vertical radiator design) @ 40'. Good performer on 80,40,20 & 17M.
VHF/UHF:
2M/440 DIAMOND X510HDN @ 38'. Excellent performance
2M/440 DIAMOND X-50NA @ 25'. A remarkable general ops & test antenna.
2M HOME BREW "Double Copper Cactus" J-Pole" @ 15' Simple design, reliable performance.
Prior calls & ops:
KB7IZE 89' - 93' (Mobile, 10-15m)
KA8ZE (Auxilliary Military Radio station, Misawa AB, JP, USAF, 90' - 93'.) HF DX, AMTOR, PACTOR, RTTY, CW and VHF simplex voice & packet. SATCOM and Moon-bounce.
AFA8TM MARS, (Far East Japan.91'-93')
N3OLO (Ft. Meade, MD 93' - 95') 2m/70cm repeaters, simplex FM & packet. HF DX
KD5LCD (San Antonio, Kelly AFB, TX. USAF, 96' - 04') HF DX
KF7RFK (Yakima, WA, 11' - 12') SATCOM & Simplex VHF. As always, HF.
K7RFK (Vanity call, dropped the low grade "F" for CW brevity hihi)
Hope to QSO!
