[chirp_users] UV 5R Tone Squelch

[Tom Consodine ND5Y]

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.
