Re: Use of BitX40 for WSJT-X


 

Yes.? I bought mine specially for working JT65.?
I have made many contacts using that mode.?

A couple of notes:
  • JT65 runs on USB even on 40 meters - so you need? to use a version of the Raduino software that supports changing sidebands.? A pushbutton has to be added to swap
  • I made a small circuit board with 2? 600/600/ ohm cheap audio transformers to isolate the receive and transmit lines from the computer
  • I also added a VOX circuit on this board - the transmitter is keyed when the software starts sending tones.
  • I limit my output to 2 Watts and have made no changes to the cooling of the BITX final transistor?
