Do you have any error messages when running the Synthesizer calibration? (Owner's manual, Calibration Procedures, Synthesizer)
If the synthesizer is out of lock, the receiver will still produce some noise and possibly what sounds like signals. But it'll be way off frequency, which would explain the inability to transmit. Ron AC7AC -----Original Message----- Thanks to those people who replied to me off list with regard to the ERR TXG problem Having checked out my dummy load and all connections to the K3 I could find no problem. Trying to set the TX config for the PA was OK on all bands apart from 10MHz When going back to receive the 10Mhz band sounded odd, no cw sations heard that were there prior to testing, changing bands down to 7Mhz and then back to 10Mhz restorednormal recieve with CW staions audible. Again trying to check for 50W out the rig would then show a varying output and the SWR varying. Recieve again was odd. The main tuning seemed to vary the frequency but what that frequency was I dont know. I should have checked with the signal generator in retrospect. I decided to re do Cal Syn and since doing this the rig seems to be working as described with no problems on 10Mhz receive or transmit. Thanks to those who replied to my request for help.
