Whisper receiption from 2020-12-31 to 2021-01-17 on 137 kHz
|
I am using a Kenwood TS-590S connected to two different antennas joined together in a transformer, Marconi T and a loop, 80 meter long wire surronding a big tree in vertical position.
My recieption setup is placed 10 km away from the transmitter, at my summer QTH. I have tried to use a Miniwhip instead of this setup without success.
