You can use a lot less gas by using a directional antenna DF work. Then use 
the savings to buy a 3 element yagi and attenuator, like the ARROW beam.

Or build a hand held beam. http://home.att.net/~jleggio/projects/rdf/tape_bm.htm

Then you can also use it to talk/hear the LEO sats with a hand held.

To the original question - Perhaps he has an echolink type node on that 
frequency?
