[Racal] 6793 help needed please

[Paul Wende]

Hi group,

I have just acquired a nice 6793 which has a strange problem. The radio
seems to work fine except when you go to SCAN or SWEEP, it makes a funny
digital noise, the displays flash randomly and the FAULT light comes on.
It passes BITE no problem so I don't know which board to start
troubleshooting. After this occurs, you need to manually enter the freq.,
change the mode and press a few other buttons and it seems to go back to
working fine, except of course, until you press the SCAN button again. I
would really like to get this repaired so I can bolt her into the rack.

PS the battery was shorted, I removed, zapped it and now it holds a charge
but I am still going to replace it.
Also, I read somewhere that pressing the ENTER key while turning on the
power, starts a reset function. Anyone confirm this? What does it do?

Thanks all,

Paul
