I'm using a few UV 5 R's on a commercial UHF repeater. The frequency is a bit congested. Here's the problem - The UV 5R seems to hold the squelch open for about 2 seconds after the repeater (and thus the tone) drops. Is there a timer that anyone has found that determines the time that the squelch is held open after the tone drops? This is most annoying to hear snippets of other companies transmissions - especially one digital repeater.
Thanks for any input.

What happens if you turn of menu 35, 36 and 37?

35, 36, 37 all off already. No help there

Menus 35-37 will have no effect.
If the UV-5R is programmed to receive PL tone or DCS code (Menu 10 or 11 set) and the transmitting station drops the PL tone or DCS code with out making a 55 Hz PL STE tone or 134.4 Hz DCS turnoff code then the squelch on the UV-5R will remain open for about 2 seconds.
On most real radios when this happens the squelch closes within 1/2 second or less.
There is nothing you can do to change that.
It is either a poor engineering design or due to limitations in the RDA1846 SDR transceiver chip.

Exactly what I'm seeing.
That's why I asked if anyone has found that timer, and can it be changed? or is it a firmware/chip shortfall...

If you can't get it corrected, perhaps you found a fault in a $40.00 radio that can't be corrected.You might need a 'real' radio that fits your application. Skip KS5KIP
