Hey man,

I'll number these so it's easier to converse about them.

1) Mercury SRS

2) R3 Receivers on 3.24, 16 Ch UDI, Dieect, FS off, 10ms. TX is latest software.

3) I posted to their forum, waiting on response.

4) All other telemetry sensors are perfect and cause no anolomolies in signal quality. Everything works great until I plug the PB tememtry into one of the R3.

5) As far as reception vs telemetry corruption... signal strength in flight looks normal. It's the quality that goes haywire, regardless of strength, so a range test is likely a moot point.

6) The most disturbing thing is that the Q values don't come from the PB, they come from the R3 directly, which is frightening because it means that somehow the PB is jamming up the receiver with noise.

7) Curiosity has me wondering whether the anomaly is telemetry only or actual signal quality, but operationally I don't care... it works 100% or it doesn't. It's in a turbine that I'm not feeling like turning into a Guinea Pig.

8) I called Chief where I bought it and he told me I was the first with an issue, but, others may be chalking up low Q to distance. My clue was that it lasted 100-120s per receiver, and I was not that far away that long. Then I started noticing the phasing of the disturbance was consistent. Then duplicated it on the bench but it require waiting the 11 minutes before it started. I doubt others have gone to this level of analysis, so I can't really take his statement as meaningful.

9) Chief told me his buddy lost 3 turbines in a row on CB200s. Has anyone heard of this? I called ZB and he hasn't. Haven't seen it in the forums at all. But I did find a thread where it seemed PB SRS systems were crashing many turbines. Hmm. More chaff to sort through. I'm calling Chief today and asking his friend to get ahold of ZB.

Thank you for your time!!!

Have you discussed this with Richard at Powerbox?
Just out of curiosity, are any of the other telemetry sensors acting erratically?
I'm not sure if you are saying that this is an actual RF (reception) problem or simply a telemetry display issue. Watching the video it's hard to say which one it is.

A quick test would be to run a range test (10% output power) and see if you lose the link as you walk away from the plane.
