I just received by "repaired" scanner after 4 months at RS service in FL. But I still have the same problem. The scanner decodes digital signals for a few minutes to 1/2 hr after being turned on, then stops. All I hear is the raw digital feed on the APCO 25 channels. It seems like a heat problem, but I was hoping someone else had a similar experience and maybe a fix. Thanks, Gregg, N2UUP
