A lot about what you mention is probably a level set issue between the cards/modules in play.
I would suspect the main reason for the dual squelch layout is how the micor, msr and various other similar circuits were used for more than just voice audio. The Squelch Gate Module is probably much better at picking a signal out of the noise, where with the case of voice audio we probably can't or don't want to listen to that level of signal "into the noise". But it's hard to knock the good performance of the micor squelch chip. cheers, s. > --- In [email protected], [EMAIL PROTECTED] wrote: > Yes, but I've found no use for the latter, as all repeater > controllers made today couple the audio gating & TX keying, > IOW you can't have a situation where the repeater will drop > even though audio from the weak station is still passing, or > the repeater hangs on a weak signal that isn't quite "breaking > the squelch".
