That's a fantastic price. I'm using a 600/600 ohm audio transformer to
isolate an earth-loop problem between the rig and the PC (extracting the
audio to feed into the sound card so I can get SSTV and DRM pictures
using MMSTV and Easypal).

I intend to try transmitting DVB-T on 438 Mhz but from what I have
read doing such will result in extra bandwidth due to sidebands.
