My 736 after a few minutes running starts scanning. Does it on 2 and 432. Any ideas? Thanks Mike

Can you stop it? Could it be some incorrect setting? The information is really insufficient to say much. I'd try checking the switches first.

It will stop if you use the CHANNEL setting. It is not a setting problem. Something is telling the CPU to SCAN.

Could this come from the mic up/dwn switch? What happens if you remove the mic?

There is no mike connected. This starst after 10 minutes or so. If you turn the radio off and back on real fast it is ok for the next 10 minutes or so. If you put the radio in the ssb or fm channel position it will not scan. I doubt if some thing is heating up be cause of the way it works if you un power it.

Scanning is started by the up/dwn buttons either on the microphone or at the rig. So I would start there checking for a bad contact.

It starts scanning after 25 minutes. I REALLY doubt that after that amount of time a short appears. Once it starts scanning a push on the microphone PTT stops the scan but then the VFO will not tune the radio.

I did not just consider a short. However, a dieing capacitor could lose its voltage. A contact could be marginal and thus all of a sudden be interrupted.
