Racal RA6790/GM BITE Error Code #15

[MARK R PECKHAM]

Does anyone know what error code 15 means for the Racal RA6790/GM receiver.
I have lost all reception as of this afternoon.

Thanks,

Mark.........Didn't it reanalyze and get by that after turning it off, then
back on? You know when it goes through the test deal at turn on?

I don't have a 6790 these days or a manual, but I found the answer in the archives of premium RX:

Either no filters are installed in the system, or the synthesizer
signal strength is out of range prescribed for BITE.

Probable fault A2

I think I'd start by pushing down on the rom chips to make sure they're seated properly, and then rerun bite.

Next, I'd pull one filter at a time, and try bite after each one.

Then I'd try disconnecting and reconnecting the all the connectors involved with the A2 board in case one of them isn't making
good contact.

If these ideas don't work, you'll probably need a service manual and test equipment. The 6790 service manual wasn't nearly as
detailed or helpful as the ones I have for my Harris and WJ's.

The 6790 doesn't do a bite test every time it turns on - just if the memory back up battery is dead or has just been changed, or
if you manually start it.

Replacement batteries are hard to find but it's easy enough to solder in a battery holder and use a couple of size N or AAA
nicad batteries.

Good luck!

When BITE shows error 15 and receiver is nonfunctioning, press "LOCK"
button and while continuing to press it , press and release"CW" button, then
release "LOCK" button. Receiver will complete its self test and come alive.
If reseating filters doesn't eliminate error 15 on next BITE test, turn
circuit board A4 IF gain control (R39?)ccw to decrease gain somewhat and see
if cures problem.
