There was loads of FT-8 testing yesterday. People were pushing up with one computer TXing through their 13cms gear and decoding with another computer from the SDR downlink.
The ability of several proven web SDR downlinks is wonderful in enabling you test your uplink. Regular 23/13cms SOTA activator Andrew G4VFL was copying himself using his SG Labs 2W transverter and 12 ele Yagi.
Which I believe was the reasoning behind setting up the WebSDR at Goonhilly, so that people could concentrate on the TXVertor plus antenna.
I wonder how long before we see a firmware upgrade to a 2.4GHz WiFi router so that it can produce a few milliwatts of SSB or CW (created and driven from a PC) DD-WRT-HAM ?? Add amp and antenna and away you go …
(the PC software generating the SSB/CW/Digital modes, also acting as an WebSDR client for receive).
No. That’s really not what I’m talking about.That’s just what it says - an up converter and an LNB. You still have to get the LNB IF down-converted if you want to receive on the same radio that you are using to up-convert.
Left hand side of advert - up-convertor, right hand side of advert - down convertor.
The down-convertor injects a 9GHz signal in, it seems - what IF is that going to be; 10,490-10,500MHz minus 9360MHz = 1130-1140MHz - a little below 23cm. I wonder why that is?
The LNB/Down convertor is already sold out, I can’t find the up-convertor in the price list. So all very new of course.
It’s not in the wrong place, it’s a second payload on a satellite that will provide TV and data services to Europe, the Middle East and Africa. AMSAT-DL were lucky to get the opportunity.
The whole of North America (and a lot of South America) are not in the footprint as well. Once AMSAT-NA get their geostationary Satellite up (when, I don’t know) they will no doubt add NA coverage but I wonder if the future geo-stationary amateur satellites will ever be linked via an earth station to give half the globe coverage? Actually I hope not as it’ll just be like using a cell phone then to make DX contacts.
