[chirp_users] Baofeng UV-9R Pro - flashing causes severe squelch problem

[d at deutrino.net]

Hello again,

I obtained a pair of brand new Baofeng UV-9R Pro units a few months ago and promptly flashed one with CHIRP.

Unfortunately it seems that flashing the unit causes some kind of strange problem with squelch. I've seen this referenced a few times elsewhere when searching the problem, forum posts, Amazon reviews etc, though I don't know if this happens with all units or just some (and would love to hear info from anyone who's flashed them).

Observations, hopefully somewhat accurate:

1. After flashing the radio with CHIRP, when it is tuned to a continuous channel such as NOAA weather radio, the squelch cuts in and out so badly that the radio is more or less unusable.

2. The radio, before flashing, and after factory reset, reliably receives the same channel without squelch problems when placed in the same location, which indicates that the problem is not one of low signal or interference.

3. Setting the squelch to 0 in the menu does not have a positive effect on the problem.

4. The squelch problem can be temporarily "cured" by pressing one of the buttons, e.g. the menu button. At this point, the squelch will perform normally for several seconds before going back to the broken behavior, in the case of the menu button, possibly when the button press "times out".

Has anyone else noticed this or know of a fix or workaround?

I am happy to assist debugging if desired. Just trying to see if there is anything I've missed before opening an issue.

Thanks-
