[Amps] TRANS WORLD TW500A-RM

[Steve Thompson]

I'm sure that somewhere I have the user manual for the TW500 
mobile version. If I can find it and get any spare time over the 
holiday I'll run it through the scanner.

In answer to Emile's original question - I imagine the main part 
of the 'FSK option' is a LOT of extra cooling.
