I found a LOT of 3 (2 pocket AM Radios and a portable AM Aircraft Band Radio)
on eBay a few years ago and won the bidding for less than $5.00. I made a 4
element beam for 130 mHz and a 4 step attenuator and use the Aircraft Radio for
finding noise, works great.
I suppose it goes without saying FM radios are not good for finding line noise
