My Plan
Posted: Tue Apr 23, 2019 3:38 pm
Hi Folks
I'm completely new to Amateur Satellite, and I just wanted to write down my current plan for those who are interested, and hopefully get some feedback.
Right now, I have an RTL-SDR connected to my Sky Dish (still pointing at 28.2). My LNB is powered by a satellite receiving using a splitter (the other output going to the RTL-SDR with a DC-block F connector)
I have the following things on order:
90cm offset dish, with an Octagon Green Single LNB
Dmyco V8 satellite finder
MiniTiouner-Express
25m of RG-6 (twin feed)
Next steps:
1) Try and improve my SNR on NB SSB RX. Hopefully this should be pretty easy compared with my 60cm Sky dish pointing the wrong way
2) Try and receive the DATV signals from OSCAR-100. Using the above equipment, should I be able to receive the DATV signals from OSCAR-100 ? Or is my dish too small?
Once I get good RX, I'll then try to TX SSB ....
3) Purchase a LimeSDR-Mini and get it going with SSB RX (with SDRSharp on Windows)
4) Try and get SSB TX on 13cm working with the LimeSDR-Mini, probably using SDRAngel. I don't really know how to test this though - can the LimeSDR RX at the same time as TX?
5) Purchase an ebay 2.4Ghz 8W PA and build a 2.5 LHCP antenna that can fit infront of my Octagon LNB, and try to talk via Oscar-100!
Once all that works, I'll then try to TX DATV ....
6) Try and get DATV TX across the shack from the LimeSDR-Mini to my MiniTiouner (on 13cm). Probably use DATV-Express for this
7) Try and use my 8W PA + 90cm dish to send DATV to Oscar-100. Could this work with a really low bandwidth?
Any comments or suggestions welcome, thanks!
