The SCS PTCIIPro is truly the best
radio modem money can buy. It employs
proprietary Pactor II modulation for
speeds up to 1200 baud with data
compression, 800 baud without., and now
PactorIII is an available option that
increases that 3 - 5 times faster. The
digital signal processing increases
receive sensitivity by 18 dB - that
like increasing the transmitter output
of the distant station from 100 watts
to over 6000 watts!
