Saber 3 help.
I have a saber 3 that is having a problem I've never seen before. Lets say I have the radio on Zone 3 Channel 4 everything works fine. When I turn off the saber and turn it back on it reverts back to Zone 1 Channel 4. Why would this happen? Any thoughts? By the way. This is a saber 3 non secure 460-490. Thanks in advance.

S3 question/problem...
A recent (2 or 3 weeks ago) thread on this board described in
great detail how the channel selector switch on a Saber works.
Instead of being a pole switch it's rather a binary selector, and
if one of the contacts is intermittent the kind of thing you are
describing can happen. The answer in the case that was at
hand was to replace the switch.

With automatic channel reverts, the channel switch is defective as the intermittents cause the BCD outputs to change to a previous state instead of remaining on the last selected channel.
Saber IIIs and the like do not have selectable revert channels like the Systems models have, especially in the emergency options.
I'll take odds that there is a lot of play in the switch, or the switch is extremely easy to rotate from channel to channel, as well as the lack of detectable 'clicks' when rotated, if so, this is a stong indicator the switch is defective and would require replacement.
If you are handy with soldering, you can replace the switch yourself, or remove the controls/button flex as a complete assembly and retrofit that in your radio.
The adhesive used on the button flex is quite stong and if you exert too much pull on it, you run the risk of tearing the flimsy assy.
You can LIGHTLY heat the frame to soften the adhesive as to facilitate an easier removal, but not too much heat.
I have a few complete assemblies if you prefer to replace yours.
I wish you good luck!

Very interesting. I was thinking that maybe there was some sort of battery backup in the radio that memorizes what the last channel was. At least it seems like an easy fix. I would have never thought this would be the problem. I almost immediately assumed it was the front main board. How much waould the entire assembly be? Thanks guys. You are all the best!
Yes I did and it always resets itself back to Zone one. I basically "fixed" the problem by reprogamming all my necesary channels into zone 1 so even if I turn it off and back on again i won't have to go through the hassel of fumbling through the menues. I know that I eventually have to do the actual repair though.
