With my current license, I have privileges for 30 MHz and up (10 metres and shorter) - it'll take some further studying and testing before I'm allowed on 15 metres. But if I can, I'd still like to start with digital before then. If anyone would care to suggest transceivers that function on 30+MHz, I'm interested in your recommendations. (Or if My existing handheld is a Kenwood TH-D7AG; it has built-in APRS, though of course with its rubber-duck antenna, range is questionable. I have a Win98 laptop able to run MultiPSK, though I don't have any cables to connect it to the handheld (or anything else). (If you happen to know how I might get my hands on such a cable, it would be appreciated...) What I'm currently most interested in, are the fundamentals defining the various digital modes, and figuring out how to figure out which ones are most useful in various conditions, and from there, figuring out what features in a digital mode help or hinder. Once I have my digital-radio feet under me, I'm also interested, to an extent, in setting up some sort of packet BBS, given my fond memories of dial-up BBSes twenty-odd years ago.
