[Premium-Rx] Receiver Selection

[w3jn]

The Collins 95S would be an ideal receiver for this application.  Small, 
easy on the power, and good stability/freq resolution.  I believe you can 
buy them in a VXI package as well if you're planning on installing 8 of them 
at one location.

I don;'t know how much they cost now, but 10 years ago they were about $4K 
each - a steal back then.
