Jorge,

I suggest that you try to find a portable (or mobile) RX that tunes 80M, 
then walk or drive around to try to hear it. Such products are often the 
result of rectification by some non-linear junction, and are 
re-radiated. The Tecsun PL-660 is an excellent consumer all-band RX that 
sells for about $130 in the US. It can detect AM, SSB, and CW on the HF 
bands, and covers from long wave (~ 250 kHz) up to 30 MHz, plus FM 
broadcast and the AM Aircraft band (~ 118 MHz to 132 MHz). Sensitivity 
is pretty good.

Many ham FM talkies have the additional RX capability from the AM 
broadcast band up to 800 MHz. I use my Kenwood TH-F6A for that fairly 
often. Sensitivity falls off a LOT outside the VHF/UHF ham bands, but it 
will hear stuff if you're really close. There are also ICOM and Yaesu 
talkies with this capability.
