Hello, I am a new ham and I am wanting to branch out into digital modes. I am not really interested in FT8/FT4 as much as I am RTTY and PSK31. I have made several hundred voice contacts with my current setup. I have an FT757GX1, manual tuner, and G5RV in the air. What would be the cheapest and easiest way to get into these modes? Would love to try CW as well but do not want to invest 100 or more for a key. Call me cheap if you want but I have mouths to feed still lol.
