CTCSS detection period settings #698

Open sq8vps opened 3 years ago

sq8vps commented 3 years ago

The CTCSS decoder often detects false signal and turns on the repeater. It is not possible to eliminate this issue neither by setting the threshold high (as the high enough threshold makes the repeater unusable - even strong signals cannot open the repeater), nor by setting the threshold low (as the repeater is almost constantly open). It would be great if there was a functionality where you can set CTCSS detection period to e. g. 200 ms to avoid false repeater activations.

try CTCSSThreshold=150

be careful it overflows after 255. So 300 means 44 only.

sq8vps commented 3 years ago

Tried lots of values of CTCSSThreshold and it didn't help. Seems this is a problem with detection period, not detection threshold.

Threshold is basically time. try it with 150 and tell me the result.
