With my own brand of receive program the diddles on the air became characters on my screen. It was like learning morse for the first time. What a thrill to finally make sense out of what was previously thought of as 'interference'. I got so hooked on rtty that I could hardly pull myself away from the shack. In fact I worked so late getting the system working, that I couldn't find any rtty stations to receive when I'd make a change in the program. Very frustrating! Now you know the beginnings of my rtty career. Now I'm working on the transmit part of the program. Now to the questions: 1. What I'd like to know is what rtty modulation techniques are being used, what are the 'usual' freqs and where on the bands that type of operation can be found. 2. Any tips for a neophyte rtty operator? 3. What rtty stuff is happening in the SF bay area. TNX es 73 de KA6SFV (Rob) sk
