Bug #11639
openFH8P-Pro Squelch Level Decibels Need Setter
0%
Description
Baofeng radios use squelch settings 0 through 0+n where n is an integer in a range.(Describe what you were doing)
I expected to be able to set via CHIRP, for each available n, which decibel value that corresponded to. (Describe what you expected to happen)
The corresponding left-side-menu item that appears when using other radios was entirely absent. (Describe what actually happened instead)
This works with the UV-5R, on which the F8HP-PRO is fully based. (Has this ever worked before? New radio? Does it work with OEM software?)

Hi, sorry for not being clear. Let me try another way.
BF-F8HP-PRO has six squelch "levels" including zero. But what do they actually mean?
Under the hood, they mean decibel levels. (And with factory settings, those values are quite close to each other.)
Using CHIRP, could it be made be possible to set, per squelch "level" (integer 1-5), where the decibel cutoff for that level actually is? I've done it before with other radios. I took a screenshot of the relevant interface for you, but am not sure how to include it via this tool! Thank you.

In most radios I'm more intimately familiar with, the definitions of those levels are in the calibration data and can be changed. CHIRP doesn't know what the radio's actual squelch levels are, nor does it tell the radio what actual signal level corresponds to, for example, a 3. The radio provides a single index for CHIRP to set (the 0-5 you see) and that's all we know. It's up to the radio to determine that. Also, it's likely the radio has different squelch level settings for each band it supports (which is why it only stores an index for the setting) which means whatever CHIRP were to show you (if it did) would not be universally correct.
Further, the driver that supports the BF-F8HP-PRO supports a number of other very similar models, all of which could have different definitions.

Adding some background to this. I believe CS is referring to this:
https://www.miklor.com/COM/UV_Squelch.php
...which is referenced with some other examples at
https://www.reddit.com/r/gmrs/comments/vvtwfo/preferred_squelch_presets_for_baofengbtech_radios/
I was also disappointed to find the squelch setting won't go quite low enough on my BF-F8HP-PRO. (Some readable but staticky signals do not break squelch at setting '1', and I wish they would.)
I hope this is helpful!

That UV_Squelch page is describing the "calibration settings" I described above. They are effectively changing the definition of what "squelch 1" means in the radio. However, the F8HP-PRO is a totally different radio than the older models (including ones with F8HP in the name). The radio behaves totally differently, and if it has the same sort of calibration settings, they're in a different place and encoded in a totally different way.
If you find how to tweak those in the radio (via OEM software or something else) then it's potentially possible to add them to the chirp driver like other models that have them. But, someone needs to find and decode those before we could do that.
