Not much left
Phased verticals for 80m CW, one permanent, one (135 degrees shift) during winter.
Activity from 472 kHz to 432 MHz, all modes.
Set-up for 472 kHz
Overview: TS480 (RX), HEXFET TX and power supplies
HEXFET TX. Low pass filter on the rearside, toroid under the fan. Oscillator is a DDS unit from China (30 Euro, ebay) working on 944-958 kHz, followed by a (keyed) divider ic 4013 providing two outputs with 180 degrees shift, and driving two driver ic's ICL7667. FETS are IRFP360LC. Tx runs maximal 600 Watts. Efficiency 85%. Overrated power supply 50 Volts (25A) is a surplus telecom unit from a fleamarket ($30). TX/RX relay and CW-VOX on the right side of the board.
Tuner for tuning the 160m inverted L to 472 kHz. Estimated efficiency of the antenna: 5%
Antenna connection floating.....
Transceivers: Kenwood TS480, Yeasu FT100, Elecraft K3, KX1.
Home made transverters and transmitters for 500 kHz, 70 MHz.
Linear: home made with 3x813, Expert 2K-FA.
Steppir 3 elements for 7-50 MHz with 1 extra director for 50 MHz and 3 extra elements for 70 MHz (thanks G4EZT)
I use no longer the ''trombone" for 30/40m but a 5 m long dipole parallel with the boom and the director/reflector as a top load. Impedance about 12 Ohm (QST june 2007).
Inverted L for 1,8 MHz.
(Phased) vertical(s) for 3,5 MHz.
Sloping dipole for 7/10,1 MHz with traps.
Beverages in 4 directions; DHDL loops
DXCC: nr 1 Honor roll (340) mixed and SSB, 339 CW
160m: dxcc 305 cfmd, WAS and WAZ(40 zones)
DXCC challange: around 3130 band points
50 MHz: WAC, WAZ 30 zones, DXCC 169 countries worked
Winter: house, beam (still with trombone) and inverted L
