Good discussion of using two HF rigs with transverters for satellite comms
All,
Flex has an interesting article on using two rigs for full duplex operations using SATPC32.
http://support.flexradio.com/Downloads.aspx?fr=1
Look for: A Full-Duplex VHF-UHF Satellite System using FLEX radios
While some of the article is specific to Flex radios, there is an excellent discussion of considerations for transverter LO frequencies which is relevant to most rigs.

Let me get this straight:
Flex 1500 $650 Flex 3000 $1700
Plus transverters:
L144-28HP $480
L432-28HP $500
That's $3,330!!!!!
The info and concept might be good, but that's it.
Get a Funcube Dongle Pro+ (wish AMSAT NA would negotiate a deal with Howard and sell them to raise funds) if you want a SDR receiver and an FT847, TS2000, IC9100 and you are miles ahead.

Before you 'tee off' on anyone, Stefan, try reading the article. The first paragraph sets forth the authors goal. He was not so much pushing the Flex line, but rather his goal was to work with specific parameters and equipment. The reality is that there just is not 'one best way' to do this stuff.

You are right!
That's why is said:

Hope that helps,

PS Remember when FLEX made these BIIIGGGG promises at one of the AMSAT meetings, just to discontinue their Vhf/UHF units! I guess we are just not worth it. Hope the AMSAT board remembers that the next time Flex shows up with another promise....
