[Icom] 746 squelch or whatever

[tom johnson]

Lately, when tuned into a strong signal, my standard IC 746 will go
completely silent for a second or so when the signal stops. It is almost
like the squelch engages for a second or so, and then it lets off and begins
to act normally, until next time. The squelch setting has no effect on this.
Obviously, I have pushed, twisted, poked or twiddled something to cause
this. Does anyone know what it might have been? I am still learning this
thing, and really appreciate any help you may give. Thanks in advance.
