It's all about the Software

Hello,

I am using SDR Console to receive NB signals from Es-Hail 2.
To compensate for the LNB LO drift I use geostationary beacon feature.
Unfortunately spectrum plot of the plugin is freezed to the frequency range which does not always allow me to set the correct offset.
The attached image depict the issue I have: the beacon is off the frequency over +350[kHz] and its signal is not visible in the geostationary beacon window.

My question is: is possible and how to setup geostationary beacon feature to have its spectrum somewhat wider than 10.48965-10.48985[GHz]?

Thank you!

If it is consistently off to the same side correct your definition to use the actual offset.

Sigi can probably be induced to rhapsodize about how he has stabilized his down-converter if you are interested. He has posted many times about what he has done on the groups.io list. One thing he did is replaced the down-converter's crystal oscillator with a much more stable TCXO. After that keeping the unit out of drafts helps a lot, too. Oscillator replacement should bring your error range down to something usable. At the very least keep your down-converter's oscillator temperature as constant as you can manage. The more accurate the oscillator the more likely that your transmitted signal will appear to be on the desired frequency out of the satellite. With a big drift you might drive yourself out of band.

@jdow I plan to inject reference signal to make LNB operation correct. For now I want to use geostationary beacon feature. The issue is that its waterfall frequency range is to narrow.
Is there a way to make it wider?

Nope - at least not that I know of.
