Most VHF/UHF rigs have "9600 baud" capable ports built into them. Without going into a long-winded explanation, the port bypasses the pre-emphasis circuitry of the radio so that 9600 bps operation is possible. Plus, you have to get a 9600 baud TNC, like the Kantronics KPC9612. Looking at a few hundred dollars for that.
So, most of us have grown accustomed to "1200 baud" only on non-9600 baud radios.
Scott KD5NJR and I have experimented with the new "8PSK" modes that were added last fall to the FLDIGI suite of programs. Running 8PSK-1000 is the equivalent to running 3000 baud. Yes, two and a half TIMES faster than a standard TNC. I was sent him a 77K file in less than 5 minutes.
I encourage everyone to try out the super-speedy 8PSK modes on VHF/UHF, especially considering you will have no added cost outside of your soundcard interface to the radio.
