Motorola XPR4550 analog RX gain settings help

[CFuerst20]

There's been this a little annoying issue with my Motorola XPR4550. On analog mode, it seems to be muting out some stations the station I'm receiving from is a fixed station, so it's not moving. I have a feeling, it's the RX gain settings, but I really don't know what a change in the CPS, could someone please help me?

Is the radio on tight or normal Squelch?

Normal I tried both just to see what would happen.

Ok for the most part you'll want normal squelch I've frankly never used tight. I not knowing the range or your operating conditions, I really can't comment further. I don't know of anything personally in the CPS that will help to bring a station cutting in and out in. If you didn't change the RX settings the defaults should be good.

What band is the 4550 on and what is a little more about the station? (antenna etc). what is the range of the station you're trying to receive, and have you heard him on other radios at the same distance and time or close to it?

Its on 70 CM UHF and the station is around 10 FT away

try getting further away from it could be over loading the front end. Is this on a simplex frequency or?

Simplex it's only some stations that get muted.

Regardless, at 10 feet there could be front end overload. I'll confess. I don't understand the need or possible use case for multiple radios at 10 feet however. I don't know what all the radios are, their power levels and I have not benched them all on a service monitor. At this point anything is only a guess.

Its 10 FT because its an Allstar Link node for ham radio it's putting around 5W of power from the node when I was at the SDR I noticed it happened at the RF dip point it's a little annoying that Motorola have a set your own gain setting but what can you say it's a Motorola.

I hope up get it sorted out. I use Motorola radios a lot on ham usage and honestly they have no problems. I know of at least two cases there being used on an amateur repeater and those are connected to an AllStar node and those two guys aren't having any problems. That being said they're repeaters not a simplex node so that could be a different use case. Again good luck.

Yeah, I was playing around with the radio for my ASL node. A Kenwood TM-V7A and also the configuration of ASL. I did adjust the TX audio, and it made it much better. It still does it a little bit but not as much as before. I do plan on swapping out the Kenwood for something a little better, but who knows?
