The answer is no. I’ll be on Es’Hail 2 myself, so will look at the LNB issue once I have a dish and LNB organised. There will be some Doppler even though Es’Hail 2 is a GEO satellite.


As soon as Es’Hail 2 has been commissioned I’ll get a dish ordered and look at this issue.

Hello OMs,

it is possible with SDR Radio to lock on a signal (like AFC with FM) and receive with an second VFO another signal in USB which follows the lock on the first signal?

The problem is that the used LNBs for reception of EsHail2 Sat often drift several 100Hz in a few minutes.

On the narrow band HAM transponder two frequency-stable beacons are planned on the lower and upper band edge.

If you can lock to one of these beacons und demodulate any SSB signal between those following the drift of the beacons you won't have to retune every few seconds.

Anyone an idea?
