Hello to all

I know this is a selling forum and may be asking in the wrong place.
Anybody by chance have an idea why an MT1000 (VHF 99 Channel H43GCJ7190CN)
simply will not "close" its PL when the switch is flipped to close PL? I
have checked and rechecked RSS settings for RX PL and have verified the
switch is fine.

The green light does not blink regardless of whether correct PL is being
received. I tried enabling priority scan with PL/DPL but that hasn't helped
either.

Thanks, Mark W.
