[Elecraft] KX3 2m transverter

[Steve Bunting]

Hi everyone,
 
The transverter in my KX3 no longer works and I would like some advice.
 
1) The menu settings have been verified as correct
2) The internal cables are correctly connected
3) The radio moves to 144MHz when I press the band button
4) There is band noise, but no signals are received from my HT nearby
5) I transmit on the KX3 and I get a "Band end" error.
 
Any suggestions?
