What to do if my GRE PSR-500 will not scan when SCAN key is pressed?
- EElizabeth GrayJul 31, 2025
If your GRE Receiver isn't scanning when you press the SCAN key, first, try tightening the squelch, applying an attenuator, or locking out any 'birdie' frequencies. Another reason might be that the squelch control isn't properly adjusted, so turn it clockwise until scanning resumes. Ensure that you have more than one channel programmed and enabled for scanning. Finally, the scanner may need to be reset or initialized, so follow the steps to do that.
