[NLRS] 1.2 ghx eme

[Doug Reed]

I really liked the link to the 10GHz EME RX setup.
<http://www.pa0ehg.com/dl0shf2.htm> Using a 1M offset dish and LNB for
the RX down converter is quite a cheap option. The 10GHz RX system for
the QO100 satellite is similar and there are LNB mod articles for
higher stability. Add a cheap RTL-SDR dongle (or something better) to
receive around 630MHz to finish the RX system. Would be a cheap path
to SWLing 10GHz EME.

If I remember correctly, the Avenger LNB and similar models of LNB are
linear polarized and changing the operating voltage selects horizontal
or vertical polarization. The common DSS TV LNBs that come with most
small dishes are circular polarized and polarity is selected by
voltage. There are even more expensive LNBs that combine selectable
linear and circular polarization.

This would be a pretty low accuracy local oscillator chain so you'd
probably want to plan on having some sort of 10368 weak signal source
so you could tune your SDR RX to the correct ballpark before looking
for the EME signals....
