I have a Unication G5 that I use to monitor my local P25 system. It's a great radio, but my biggest complaint about using it is that different users have vastly different volume levels. At a given knob volume level, some users on some talkgroups will be so quiet they are almost unreadable, while other users are almost painfully loud.
Listening comfortably on the G5 requires a lot of manual volume level management to increase volume when quiet users are transmitting and decrease it when a loud user comes across so it's not painfully loud.
Do Motorola APX radios have a feature that normalizes received audio (basically an AGC for the final audio signal), so that transmissions come in at a relatively consistent volume?
I'm not seriously considering getting an APX for NAS, mostly because it will be very expensive and in many ways more limited than my existing G5, but I'm curious to know whether professional P25 radios have such a feature. I imagine it would be critical for a professional public safety radio where properly hearing transmissions is critical, but I did some searching and I've never seen any explicit mention of it.
If they do have such a feature, is it a built-in feature or is it an add-on option added to the codeplug (and if so what is the name of it)?
I am aware that there seem to be some flashport options that improve audio quality on the transmitting end (e.g. QA09006 Adaptive Noise Suppression and what Motorola calls the "Adaptive Audio Engine"), but if these are in use on the radios on my system, they don't seem to be sufficient in normalizing audio levels because there are still big differences when I monitor with both sdrtrunk and my G5. I figure there must be a feature that normalizes audio on the receive end as well otherwise I would assume that the actual public safety users would be complaining about the differences in audio levels and having to manually adjust the volume all the time.
Thanks!
