N4ECW’s HF station consists of an ICOM 7700 transceiver powering an ICOM IC-PW1 amplifier. His back-up transceivers are an ICOM 756ProIII, an ICOM IC-746, and a Yaesu FT-897D. His back-up amplifiers include an additional ICOMPW-1 and anAmeritron AL-1200.
TransWorld Antennas TW2010 5 band vertical dipoles are used for 10, 12, 15, 17, & 20 meter DXing. TransWorld Antennas vertical dipoles TW3030, TW4040, TW6060, and TW8080 are used on 30, 40, 60, and 80 meters. Double bazooka antennas are used as back-up antennas on 40, 60, 75/80, and 160 meters.
K1ECW’s VHF / UHF station includes an ICOM 910H and Yaesu 736R with AG-25 & AG-35 mast mounted preamps, an ICOM v8000 2 meter FM rig, and a Yaesu FT-7800 2 meter 70 cm FM rig. When necessary, these exciters power a TE Systems 1454 2 meter 350 watt amplifier and a TE Systems 4452 70 cm 175 watt amplifier.
The antennas include an array of two Cushcraft 26B2 2 meter FM boomers, a Cushcraft 13B2 for CW/SSB, a phased array of 4 each 2 meter and 70cm horizontal loops, and a Diamond v2000a triband 6/2/440 vertical all mounted on a 70 foot tall Rohn 45 tower. The rotor system is a Yaesu 800DXA and the coax is all 7/8″ Andrew hardline. KU4AB loops provide omnidirectional coverage to locate weak signal stations before the beams are employed.
Note: N4ECW and K1ECW own and serve as control operators for two open repeaters atop Pilot Knob near downtown Cookeville, TN: 145.270 (-) PL 123 Hz and 443.200 (+) PL 107.2 Hz.
