[amsat-bb] What on earth (or in space...) is going on?

If you can find a local source for the Optima OTLSO model, that works very well.
The really important choice is to make sure it uses PLL technology for the 9.5 GHz local oscillator
The older Dielectric resonant oscillators are too noisy for narrow band modes like SSB

If you want to hear a 10GHz signal on one of these LNBs, then you can listen to a local beacon just south of London via this SDR receiver.

Even so, you need to let them warm up for a good 10 minutes to get the temperature (and frequency) nice and stable.

I would certainly be interested in learning how to utilize the higher frequencies without spending a fortune.

In that spirit, sure would appreciate it if the mentions of known-good hardware from Amazon & eBay could include links to the particular items.

  Hi Tom,

  I have a GPS locked 10 GHz beacon on Mt Mansfield here in Vermont and I 
  use the exact setup to monitor it.

  I use an old DSS dish and a $7 LNB plus a FunCube. IF frequency is about 
  617 MHz for the 10,368.320 beacon.

  I just looked on eBay and the LNB I use is there for $6.95 plus free
