[ICOM] IC-775DSP

[Paul Playford]

Scratching the memory:

Check the diodes in the tuner control module, or maybe even just replace 
them.

If that does not cure the tuner check the variable capacitor drive motors. 
I had two 775's that the bobbins that secure the armateur to the drive shaft 
in the motors had broken.  Repaired them with epoxy cement and they work 
fine now.
