I'm sorry to be the Debby Downer here, but I'm not so sure that the 'visual squelch level' is a great idea.
I think the squelch function can only operate well if it is loosely coupled to the pan-adapter signal. For example, changing the pan-adapter averaging slider should not affect squelch operation. However, if the squelch level is set relative to the pan-signal, people will expect squelch to break according to the signal they see on the screen.
It seems to me Flex will save complaints if the squelch control is a simple slider, off to the side with a dBm level.
I never thought about using Squelch to much because I've always been in conversations or dxing. Now that I have more time on my hands and listening to nets that are not heavily attended the white background noise is starting to get to me!! Further up the list here Dave mentions that Tim says it #.....
My question is, "Will this three year old suggestion be implemented in Ver 2 ?"
