Dogs. Clip a long wire onto their tail, and adjust the ears for perfect
reception. Dogs with long floppy ears are preferred for ease of adjustment.
Back in the '60s you could get them to bark in Morse code. Now they just
tweedle. Poodles are useless because they have RF chokes in their tails.

Lacking a canine radio, the three most popular approaches are:

1. Boat anchor receivers that tune down there.

2. LF converters used with HF receivers (that's what I use -- the converter
is hombrew).

3. Graft an antenna onto a sound card input and use something in software to
visually or aurally tune in the signal.
