Problems with K3 Calibration

[T Gahagan]

I am currently at the calibration stage of assembly.

1.
In trying to do the reference oscillator calibration(I have the 1ppm TCXO) (using method 3) I can get into the CONFIG:REF CAL menu entry, but when I tap "1" I can't get to REF xxC.  Tapping 1 seems to change the mode from CW to AM, the AGC speed, turns on the VOX, and changes the filter from 1 to 2 but I am not able to get to REF xxC.

2.
When doing transmitter gain all goes well except on 7 Mhz and 10 Mhz where I get no output power and the display says 0 watts and ERR TXG.  All other bands seems to respond as they should.  I see in the error codes that I should look at the service manual??

3.
I also have discovered that toroid L18 on the KBPF3 had a lead broken during shipment.  It seems I've heard of this happening before to someone else.  Can a turn on the toroid be sacrificed to allow enough length of the lead to solder it back in the board?

I pulled the KBPF3 out and disabled it in the configuration setup but I still have the problems mentioned above.

Any ideas?

Thanks,

I'll answer the easy one: this method isn't implemented in the firmware
yet. Just use the method that zero-beats WWV.

thanks Vic,  I suspected that was the case.  Now on to the other problem.

I highly doubt it. You should contact <[hidden email]>. The  
guys at the support desk are usually very quick and always competent,  
imho.
