Re: V3.1 Beacon Sync stability issue

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.

V3.1 Beacon Sync stability issue

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 screen...

Re: HL2 - Output/Drive control functions with PA disabled

Hi all, A bit off-topic, just to note that the same issue affects the drive setting with the Adalm Pluto. The drive scale there seems to be roughly 0.4dB per drive unit. Going from drive 100 to drive 0 reduces the output power by ~40dB (the AD9363 attenuator is able to go down to to much lower level...

Re: Issues with Geostationary Satellite Beacon View

Hello Simon, Another interesting observation about the drawing of the line in the graph: By detuning the beacon in the right part of the window, the line immediate appears in the left graph. The drawing/update of the line stops as soon as the displayed beacon frequency does no longer change. Maybe t...

Re: Issues with Geostationary Satellite Beacon View

Hello Simon, I just did some tests with the window being docked. The '+' and '-' buttons seem to work as intended (greyed out when the max/min scale is reached), however, I do not see a line in the graph as well with a docked window. Setting the zoom to max when the window is docked leaves the '+' b...

Issues with Geostationary Satellite Beacon View

Hello Simon, I'm observing a strange and not reproducible behaviour of the Geostationary Satellite Beacon View. The issue is visible with 3.0.26, but I already observed it with previous releases as well. The effect seems to be independent of the beacon sync being activated or not and the view being ...

Re: Spectrum not showing full bandwidth

Hello Charlie,

Glad to help and read that your setup is working as expected. Yes, there are so many adjustments in this beautiful software that it's easy to get one wrong by accident.

Re: Spectrum not showing full bandwidth

Hello Charlie,

Your screenshot shows the "RX-Filter" slider set to 24%. Please try setting this to 100% and you should see the entire 500kHz as selected by your bandwidth setting. (Apart from some inherent dropdown at the bandwidth edges).

Re: Starting and Stopping the Pluto

Ah, I usually use fast attack, nice catch. Thing is, the gain isn't set until the radio is started, so it must be that the gain's being set too soon and the radio needs a while to 'warm up'. Pity the poor programmer :( . Hello Simon, From my observation, I can see that the RX hardwaregain is not co...
