Toroidal Helical Antenna CTHA
This new design of the System-G uses a Contrawound Toroidal Helical Antenna (CTHA) as a source of EM waves
Tasto elettrocio per la telegrafia
a coloro che si dedicano anche al CW, presentando un simpatico circuitino
TRX Sequencer
Questo semplice circuito e' rivolto a coloro che desiderano gestire direttamente tutto il processo di rice-trasmissione della propria stazione, avendo costruito preamplificatori d'antenna, amplificatori lineari
The MFJ tuner with the motor drive attached
MFJ doesn't seem to sell the tuner I've got anymore, but this setup can be used on any tuner that has either an inductor switch where the spring detent system can be defeated or a roller inductor
