The Kenwood TH-F6A is quite user-friendly and works as a general 
coverage RX from below the AM BC band to about 1 GHz, but the RX is 
pretty much a block of wood at HF and below.  It's good when you're 
close to the source, but you won't hear weak signals.

Another suggestion, Paul.  If you suspect electronic noise sources, 
something with a panadapter is VERY useful for identifying noise as 
being electronic in origin (or not).  The clue is a spectrum that looks 
like humps of noise that drift around a bit, repeating at intervals 
depending on the switching rates, and with drifty carriers in the middle 
of most humps.
