XPR Had an interesting experience with my 7550e echoing my transmission today

[Tank67]

So, I said something over my radio (analog channel that has a repeater), then I overheard the latter portion of what I said echoing over and over on the radio of the person next to me (we were outdoors and I wasn't close enough to their speaker that there would be an echo). Looked at my radio and saw it was rebooting but heard that transmission still coming over the air over the other person's radio. I then took the battery out and it killed the problem.

Anyone ever have something like this happen and know why it did? I did notice after that my speaker mic wasn't tightened into the radio all the way even though I was able to hear audio and transmit fine before this happened.

Was the voice portion looping over and over?

Yes, that was exactly what was happening.

The analog repeater apparently has some digital delay in the system. This could be the repeater controller itself, or if over a voted system with JPS SNV-12 voter, a delay in audio processing. The fact that your radio remained transmitting and apparently rebooting is probably coincidence unless you had VOX set on.

Edit: I will add that the radio you and the other party had, could also have delay in signal processing, especially if they have a digital capability.

It was probably a Yaesu DR-1X repeater. I will usually hear a bit of the last of my traffic after I unkey in analog. I have never had it go into continuous repeat though.

The other party had a regular 7550 but I heard other people who were using VX-261s say they heard the same thing. Did not have VOX on.

I’m 99% sure we actually have a VXR-7000 over there.

Is there an MMDVM on it? The ones that I've heard do it have one.

It does not to my knowledge.
