XPR Motorola XPR 7550

[btritch]

I have a Motorola XPR 7550. It will work just fine with transmitting and receiving DMR traffic if it's short. however, I have noticed (because I use it for amateur bands as well) that if someone goes on rather long, it drops out in the middle of the conversation and won't pick back up until they unkey and someone else starts or until I turn it off and back on. It shows the channel is busy and the LED blinking but there's no audio.
How do I fix this ? Is it a programming issue, setting or something totally different?

Thanks for the help and any suggestions. .

Could be default 60 second Timeout timer for talking, will drop someone when they hit that 60 second mark. Then, Channel Free for transmit setting in the channel specific settings, allowing others to talk radio to radio......someone else de-keys, so now someone else can finally talk. Must some long winded rag chewers.

I use a XPR7550e for both commercial and amateur use.

Hmm I'll have to find those settings and check. Nets are what I mainly do.

I too have experienced this with my 7550, 6530 and SL7550 .But I believe only when using my PiStar hotspots. I just chalked it up to frequency drift on those cheap Chinese MMDVM boards.

But that wouldn't affect OP's rx right? TOT should only affect the txing radio I'd assume.

I was also thinking this is a hotspot issue. My 7550e does this with my ZumSpot, and I still do not have a fix. I heard it was an issue with the e model specifically, and that standard 7550s work fine.

Too add to this, I only experience the same random dropouts on longer replies on the hotspots, but not on my local repeaters.
And if I have multiple of my Motos monitoring my hotspots, one will drop while the other either picks up where the other left off or keeps rx'ing.

Sorry I'm late to this thread. Has any solution been found?
If not, I would like to add some info.

I have a 7550 that drops RX audio on about 10% of calls, usually longer ones, >30 seconds. It's not an issue with my 6550s or new R7.
I found this tidbit awhile ago but haven't followed up. FYI, I am using a simplex pi-star MMDVM hotspot on BrandMeister.

"Motorola radios on repeaters with TA or in-call gps enabled could experience dropouts in the audio this is due to incompatibility with the ETSI specifications. Please update to M2021.01 release or later for full TA compatibility."

My 7550 is on R02.09.00.0001 & I am considering updating to whatever is the last FW for this unit as a hopeful solution. Since we now have to pay for FW updates, does anyone know what the last update version is for the 7550, not e, and also, what the cheapest, easiest process is to obtain it? I don't see anywhere to order/request it from Motorola.

Thanx......Len
