Hi all. I have A couple of problems on analog mode. Radio opens squelch, with white noise, when no transmission is being received. Does it worst on VHF, constantly opening, no carrier. Other radio on same antenna does not do it. Very annoying when trying to scan other band in display. I've checked with waterfall frequency analyser and found no signal to open squelch.
Other problem is really the opposite, and has been reported before, that squelch does not open and you miss the first few words of the transmission. Also on VHF.
Thank you, Shane.

I experience exactly the same problems as yourself. Yesterday I was on UHF and the squelch would not re-open unless I changed down a channel and back up again! FM mode is rubbish.

Привет всем, у меня тоже такая же проблема в увч на 2 метровом диапазоне, эта проблема решается выбрав узкую полосу пропускания. Подозреваю кварцевые фильтр.
Hello everyone, I also have the same problem in UHF on 2 meter band, this problem is solved by choosing a narrow bandwidth. I suspect a quartz filter.

OK cool Drkrek. Do you set up the channels as A narrowband, like 12.5 kh, instead of the 25 kh tat is shold be ?
Thank you.

The only fix i have found for this is not having a decode pl tone ie tsq, with just the tone setup on transmit it works flawless for me
