APX APX 7000 Audio Question

[jnasium21]

Hi all,
I recently purchased an APX 7000 from a friend who upgraded to an 8000, and noticed that when I receive a conventional P25 transmission, there is a slight "pop" sound when the radio begins the audio. On my XTS/XTL radios, on the same P25 channel, I do not get that "pop" sound. Am I just overlooking a simple setting in CPS?

Any help is appreciated!

My 12 year old 7000 pops as well.

Been a problem since Day 1. Both my 7k and 7kXE pop when the audio opens.

It's a hardware design problem with no fix in CPS.

It's the audio amp kicking on, well known quirk. If it really annoys you that much, buy a cheap speaker mic and connect it to the radio, that gets rid of the issue. Bonus...if it's a dual display model, you can position the speaker mic facing you while also having the display facing you.

I agree with the others, it got to the point where I never even notice it anymore.

I can remember somebody sending it in for repair because it bothered them so much and they got it back and it was still there.

I was sooo glad to upgrade from my 7000 to my 8000XE as I need to keep my radio on while on call and that audio amp kicking in annoyed me to no end. Still have the 7000 but don't use it much because of that damn popping noise.

I'm guessing the audio amp isn't biased on all the time to save power, and thus, when it is activated, it makes a pop. Every 7K/7KXE we have does this. Annoying, but it's also a long discontinued radio so it is what it is.

Interestingly I was sent 2 from Plantation around 2012 or so (no tags, S/N or escutcheon) for some testing and neither of those did it.

Anybody try filtering it out, like a cap in series? I've got a CCR that pops I think as the squelch closes that I've been meaning to try to mod.

Not as if it matters but, the apx 7000 is no longer supported. You have what you have.

That's not entirely accurate. The VHF and 7/800 7000/7000XE models are supported until December 2023. It was the UHF models that were no longer supported as of 2021.

New news to me, I have, 7 - 800 MHz and uhf 2. Appreciate the accurate update.

It's largely a moot point, as Joe Blow citizen won't be sending their hacked third-hand eBay special off to MSI's Depot for a $600 flat rate repair.

I actually get that.😀 Very little has changed in my monitoring life, everything is pretty much the same and most of it is encrypted.
