Recently, I had my first narrow SSTV contact with WB8ROL. I saw the signal and guessed that was what it was and brought up MMSSTV. I had earlier tried sending some CQ's but finally determined that the mode I needed was the N mode. Need to stress that to those who are planning to use these modes to get the correct one since there is a MP-73 and an MP-73N.
Question: what other modes are there in MMSSTV that will work in the narrow 500 Hz bandwidth? I understand that they are not as fast but may have more detail? I normally don't have much interest in analog digital because of the poor quality images since just one hit can really mess up a picture, but maybe there are only analog narrow modes? Or are there digital ones as well? Now the most confusing thing is how do you handle text data vs the image data? If you call CQ with the image only and you contact another station using the same mode, what do you do after the initial exchange of images? Or is it possible to do it the other way and be text chatting with someone and then be able to send an image? How do you do this gracefully? 73, Rick, KV9U >
