A Ten Gallon Loading Coil - Variometer for MF/LF


Just about anything I plan to use as an antenna will require a serious loading coil. I decided to construct an experimental

Build a 136kHz TX
I have been using power-mosfets to produce several hundred Watts for some years now so it seemed a good idea to employ them on 136kHz

Come trasmettere a 137 KHz
Un finale di potenza per onde lunghe a mosfet che ho provato a realizzare

Compact ferrite loading coil for LW antennas
What I am using for LF antenna matching is a relatively small ferrite pot-core instead of big coupled air coils

Constructing a LowFER Antenna
Getting on the air with a LowFER station is more complicated than getting on the ham bands since commercial equipment isn't available and construction is involved

Convertitore OL HF 136KHz 4 MHz
La possibilita'di ascoltare le onde lunghe, occorre autocostruirsi almeno un convertitore, se non un ricevitore ad hoc
