First off, check http://www.qsl.net/ke4mob
for some goodies. This should help out some.
Now, tune to 20 meters around 14085, LSB and tune a strong RTTY signal. At the "cmd" prompt type "mode hb, 45" hit enter, then a "k" and enter again. You should be copying RTTY. If not, then read the above pages.
I have been running a 1278 for 7 years. It has its limitations, I'll admit. It needs work to get it up and running correctly. But last night, I worked KX5JF in Austin, TX on Pactor---at an S0 signal level.
I can usually be found on 20 meters most evenings running Pactor or RTTY.
Hope this helps,
