I've been looking around (for days actually) trying to find an 
inexpensive UHF AM receiver I can build or buy to augment my power 
line tracking capabilities. It has to be very inexpensive and fully 
portable (held in one hand). I wanted to build this:


I was thinking about moving it higher in frequency as the author 
suggests on the last page. But it seems most of the parts are now 
obsolete and impossible to find. Rats!

Any suggestions for something similar that doesn't have that problem?
