>Hi folks,
>
>An odd problem popped up with the K2/XV station here. I had occasion to change all the assignments of all the TRN channel assignments in both the transverters and of course in the K2 menu. Everything works FB except the TRN 6 channel.
>
>On that channel only, the K2 VFO refuses to tune. When I spin the VFO knob, the front panel indication shows "405900" and refuses to move. If I turn up the audio volume, I can hear noise when I move the VFO knob (except in the Lock mode). The noise is not there when any other band is chosen. All other TRN channels and HF bands tune normally.
>
>If I enter a frequency directly from the keypad, (say 432100.0 for instance) the front panel indicates that the K2 accepted that frequency, but when I try to tune around, the indication returns to "405900". The K2 will keep the keypad entered freq after band changes and on-off cycles.
>
>This problem exists when the serial interface cable is disconnected from the K2.
>
>When I select RIT, the K2 front panel displayed freq changes within the RIT range as expected.
>
>The TRN6 menu settings are: FR = 432, IF = 28, OFS = 0.00, Out = L 1.00, and Adr = trn6
>
>When I had my 432 transverter assigned to TRN 4, the tuning through the K2 VFO worked FB.
>
>FYI, I'm using the KRC2 band decoder for TRN 1 and TRN 2 decoding.(not for TRN 6), and all the decoded functions work well, including VFO tuning..
>
>Anyone have any ideas why my VFO locks up on the TRN 6 channel only??
>
