These small handhelds (at least my TH-F6) are not all that sensitive at non
VHF/UHF frequencies.  
Works fine when connected to an external antenna, but the little internal
bar antenna, is a bit deaf.
It doesn't hurt to try though..  might be perfect for the signal you're

I've heard the 2 second beep thing before.  It was coming from me neighbors
car (alarm system maybe).  Luckily, he defaulted on his home loan ; )  The
signal was all over HF and VHF spaced ~maybe 15KHz.  Too long ago to
remember exactly.

I think also most of the Yaesu VX-series handhelds, the Kenwood TH-F6A, and
others include AM receive on HF.

I think the TH-F6A may also include CW/SSB rx on HF.

Also, I believe that the new yaesu FT1DR handheld covers
504 kHz - 999.900 MHz (AM) plus 108 MHz - 580 MHz (FM) and digital mode.

Lots of choices out there for a daily use 2/440 handheld also good for
