Station details:
Antenna: 160 meter windom, and 80 meter dipole in " X " configuration
connected to one coax feedline. In the shack, feedline is shorted, and
the antenna is used as a very short vertical with top-hat loading.
The antenna is run thru about 2 Milli-Henries Inductance, with an air
variable connected from the feedline to ground, forming a simple LC
tuning network.
Receiver: A Kenwood TS450S using dual 500Hz filters, audio output into
a Vectronics Active audio filter with 80Hz bandwidth. The audio filter
feeds the PC soundcard. I use software DSP filtering at 20Hz bandwidth
for very weak signals. No LF pre-amps
73 to all, and good radio-ing to you :::
