Antenna 136KHz Links →
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

40m Compact 4-Square Antenna Compact 4-Square Antenna – EA5AVL The EA5AVL 40M Compact 4-Square Antenna was designed to provide excellent DX communications on the 40m band
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
