V3.1 Beacon Sync stability issue

#1

Unread post by Jean »

Hello Simon,

With V3.1, the stability of the QO-100 Beacon Synchronization seems to be noticeably lower than it has been with V3.0.28. While V3.0.28 (and before) showed a sync stability in the order of 1-2Hz, the stabilization is jumping around by up to 10Hz and more with V3.1 build 2319.
The screenshots below show some Spectrum Lab AF waterfalls of a weak – but stable - beacon-spurious at 10.489.562.500. With V3.0.28, the signal jitter is around 1Hz, regardless of the Console Beacon Sync being active or not. With V3.1, the jitter visibly increases when the Beacon Sync is engaged. (Sreenshots taken with 3.0.28 and 3.1 within some minutes)
The instablity is also visible in the Geostationary Satellite Beacon view. The issue is reproducible and there were no signs of someone disturbing the beacon while I observed the issue.

i also see instability on the beacon lock
main reason seems to be when the beacon sends "idle" signal

Simon apparently fixed the stability issue with V3.1 build 2320.
With build 2320 the sync is as stable as it used to be with V3.0.28.

PS: Interesting to see that the discussion was done in groups.io mailing list. Assumed we should use the forum for posting issues.
