3puttbob, hello and welcome to Radio Reference!
Are you new to scanners or an old timer in this hobby? When you say:
"All functions are good except no receive."
Was that a thorough test of every function of a Uniden BCD996XT that does not have to do with the receiver receiving clear audio? When you say:
"Gets static on all known active frequencies."
If you are on a frequency that has no known signal activity, is the receiver squelched? In other words, if the receiver is scanning the seven NOAA VHF Weather channels and receiving a signal on at least one of the frequencies and breaking squelch, is the received audio just static instead of NOAA Weather? If you stop the scan on a NOAA VHF Weather channel that is not local to you, does the receiver stay squelched and no noise (static) is heard from the speaker? Trying to determine if you have a RF circuit issue or an audio circuit issue...
As for sending it in for possible repair after a review of the problem for $79... That is one of life's gambles. Fortunately in this case based on comments that have been reported here on Radio Reference, the relative risk involved appears to be less versus more. Good luck to you!
Cheers! Dave K4EET
