Now then he is wrong this time ;-)
The input is a ANALOG input. Therefore you can feed what ever you want.
Attache a bigger coil to get higher sensitivity in magnetic fields or
simply just add a AUDIO signal from your radio and the Spectran will
show it up to 1 MHz, its just as easy as that. The internal AD
converter can handle all possible signals it works like the soundcard
on the PC.

Thats totaly wrong! have a look at the NF series. It covers 1Hz to 1MHz
and has a input for external signals (audio) too. Therefore ist a very
cheap and portable spectrum analyzer for Audio ;-)

I saw something about audio output, and audio demodulation (so you can
listen to the radio signal that it's picking up) but nothing about an
audio input. Do you have a picture or more detailed spec sheet to
confirm that there's actually an audio input? When it talks about E-
and H-field sensitivity and earth's magnetic field sensors, I get the
impression that David knows what he's talking about (he usually does).
