136kHz antenna
It's consists of a 10m fiber pole which is coming out of the window of the attic with 2 * 15m toploads made of 0.32 mm insulated copper wire
136kHz transverter
For use on 136kHz transverts to and from the 10MHz amateur band. This band was chosen primarily because 10MHz computer crystals are cheap and readily available
136 kHz loading coil
27 MHz xtal oscillator, x200 divider, 180 W power amplifier with 1 x 2SK1029 mosfet under construction 400 W power amplifier
136 kHz portable station
During our stay in LX later this year I want to take some equipment for 136kHz with me
