Correct - I didn’t see your earlier post mentioning local telemetry
also being affected. Makes me believe, even more, it’s a hardware
issue.
Do you have another/different computer you can load up?

I only mentioned it because it was mentioned to me from one of the people that helped work on the code. I wasn't try to start a war against the two giants. With that said, I will sit back and watch the thread...

It never fails to amaze me how AMD CPU's get blamed for various issues--and the actual CPU's are almost never at fault! And, yes, AMD and Intel have both had an occasional "oops" impacting a specific CPU series.
In my experience, most of these "blame" issues arise from really poorly designed/buggy motherboards. Unfortunately, in practice, more of these bad boards seem to be found in low-end AMD boxes, where system builders are cutting every cost corner.
With a good quality MB, AMD and Intel CPU's both work great and exhibit similar reliability/stability....And, in case you're wondering, I run a Co-Lo center and have a few racks full of AMD boards! I measure up-times in years.

10-4, figured that out long time ago, but all the interest in using DSP in this and I thought it would work. It might on a different platform. I opened a Mantis ticket on it a few years ago. But it really is a reason to stick with PL decode and squelch as done by Motorola and GE, why re-invent the wheel? I have one remote “private” node using a HT10 and DSP. Works fine for what it is.

DSP takes a significant amount of horsepower. Ya don’t get something for nothing; reading a hardware status bit or two is a lot less intensive at the expense of additional wiring and configuration statements in the config files than decoding the stream, deriving the signals, etc. any overhead in doing so is bound to have an effect on other streams going on at that time.
and we humans don’t process breaks in audio as we do with visual perceptions.

When you run the top command, is it using swap memory? If so, that’s bad…and you need more RAM.

Mine would do it on local as well as remote and repeat. Heck, even radio tune txaudio tone had it, pl tone had it, etc.

George, Bryan,
the problem I have is not limited to a repeat. it does happen when on simple time announcements. At the time when it happens the system is at less than 35% CPU, so I kind of doubt this is a problem in the CPU being too slow.

Meanwhile on my nodes, here we’re running full DSP with URIs on 3 GHz P4’s with 2GB (IBM Think Center SFF) of memory with no problems.

it is more a function, i think, and this is based on my experiments, of how well the USB was executed on the motherboard, or whether it was done just 'good enough' to handle the predicted keyboard and mouse and probably not much else.
i had the same problems when i migrated my 3 nodes off a toshiba laptop (!) onto an HP mini-tower, strangely enough. ran fine on the laptop. stuttering and drop outs on the HP, which was 4 years newer.
put in a USB card on the bus rather than using the motherboard USB ports. has been working fine for the last 2 years. has to do with the priorities on the motherboard, speed at which the packets can be processed, bios to handle the device routines, etc. Add in the psychoacoustic effects...it's not as clear cut as to why or where the issue lies.
but, consider that USB is a compromise design...you want real time industrial strength audio and control, i think Duuude may have some PRI boards still available which will do the trick...
