Petlowany Three-Band Burner Antenna
- The Petlowany Three-Band Burner is a simple, low-cost, trapless short vertical antenna which amazingly works on three HF bands (20, 15 and 10 meters). This web page contains pictures, performance data, and enough construction details so you can homebrew your own.
Corner reflector antenna
- Do you need a high gain antenna? Have you suffered on picking up interference from unwanted direction? You need a directional antenna but a 12 element Yagi will be too attractive!
HB9Z Internet Remote Base
- A controllable TS2000 made available at HB9Z in switzerland. Antennas are Carolina Windom 160 for 160-10m, a 5-Element Beam for 20-15-10m a
G5RV for 80-10m and a V2000-Vertical for 6m, 2m, 70 cm.
ICOM 746 Temperature Measurements
- The ICOM 746-Pro has acquired a history of NEC 1678G (IC-151) MMIC and driver transistor 2SK2975 failures. The failure of IC-151 appears to be a combination of ESD damage from electrostatic charge on the antenna entering IC-151, and perhaps thermal heat.
