Tomasz, things are like this:
1) I have original screen and TX is disapearing normaly but PTT stays ON and there is no modulation going out.
2) I did not happend on SSB, only on digital, in the biginnig only after longer session or contest, but now even after short sessions..
3) When I power down and power up uBITX TX is still ON. It is only going to off if I enter Microphone jack in the socket and push/release PTT button.
No changes in Power Voltage or different antenna or even a different PC? or cable in between makes difference.. Also, it all works fine in first 5-10 minutes an then start akting like this.
?
Is this indicate mostly to these two issues possible? PTT relay or Mic/PTT socket? If it is so, I will concentrate in that way..
