35-Watt 1710 kHz AM Transmitter
A former ham transmitter mfg circa 1960 converted for AM operation on 1710 kHz
80m/160m rx loop
I used to live in an apartment complex with 980 units, all of which were outputting some electrical noise
A lowfer Receiver using a software
a software receiver that uses a simple, low cost hardware downconverter in conjunction with sound-card software such as DL4YHF's Spectrum Lab
A Portable shortwave rx loop antenna
A simple portable antenna is described that gives good radio reception on the main shortwave bands
