locking beacon is main feature for QO 100. Windows has become critical for QO100. Thanks for your reply.

I will try running windows on linux and try my luck

Hi,

I am planning to setup Raspberry PI3 based RX station for QO100. Instead running SDR Console on wine, is there any native linux software?

Thanks

Good one

Here is the partial recording:

This net is started. Net controller is VU3OBR.

I have an obstacle in 30ft from dish. Would that be a problem?

vu3jnm In your default.conf i see a wrong rx frequency (39675000 instead of 739675000). Please check your GQRX settings.

If you set LNB LO frequency in GQRX to 9750000000 your rx frequency has to be set to 10489675000.

Thanks much. will try it. You noticed incorrect rx frequency because I was playing with it and posted incorrect one. Thanks much

Thanks for reply.

RTL SDR Dongle is used to receive local FM. It is fine. I tried measuring voltage at bias-t, I am getting 12.6v.

Hi,

This set up is for QO 100 RX.

my LNB LO is 9750. I am using gqrx on linux mint 19.2. I am using 90cm dia. Using "RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA". I used SatFinder app to setup dish. I set 739.675 MHz to get beacon, but I am not able to receive any signals.

I am using gqrx software. Would you please share configuration? it will be in ~/.config/gqrx.

Also any pointer to check what part is incorrect.

I am supplyng 12V to LNB. Is that fine?
