Hi Noel

Apologies if this should be obvious, but in the SDR setup you mention for picking up the beacon is anything other than a bias tee needed at 12v for the LNB?

I think I am picking up the Arabic channel ok on the STB

Nothing else required - the 10706MHz beacon is Vertical polarised so only needs 12v feed to the LNB and then it can be found at 956MHz plus / minus your LNB frequency error but you should see it on an RTL dongle in SDR# with a 2MHz span.

Typical reports indicate it is 25 - 30 dB above the noise .

Useful note forwarded by Graham G3VZV that beacon frequencies are not exclusive to a satellite:
To assure you're receiving Es'hail-2 the following may give guidance. Es'hail-2 has two TT&C beacons on 10706 and 11205 MHz.

When you receive BOTH beacons (without having to turn the dish) with similar signal strenghts (+/- 5 dB) then you aimed your dish correctly at the 25.8°East Es'hail-2 slot.

When you only receive (a) 10706 beacon(s) and NOT the 11205 beacon you are pointing to ArabSat 5A 30.5° East.

When you only receive a 11205 beacon and NOT the 10706 beacon, you are pointing to Astra 1KR 19.2° East.

I thank the gods of house purchase from 25 years ago. I have a ground level accessible brick wall with this line of sight over my single story spam/garage extension.

I have an old Bob Platts LNB with a 0.6 NF and a 9.0GHz dro, along with a 65cm Maspro solid offset dish, also an Octagon PLL dual output to try. This gives an nice short run of coax/cables to the shack and also the opportunity to mount a bigger dish for uplink some day. I have a 40 element Loop-yagi gifted from a friend who used to use it for the Oscars. Will that better a 1M dish I wonder?
