Cool. I wonder why nobody builds this stuff directly into radio tranceivers. What I really want is a portable PSK31 tranceiver with an alphanumeric keypad, 4 line (or so) LCD text display, AA battery pack, all the PSK31 modulation/demodulation stuff, and all the RF stuff in a single box, no computer needed. I'm imagining something about the size of an FT817 and reasonably rugged. It could be single band, like 20 meters, and it would of course have a computer port for when a computer was available. That would be a way to have fairly reliable DX portable communications without resorting to satellites. I wonder why nobody makes anything like this, or builds the feature into FT817-class radios. I'm sure there'd be demand for it.

For another, the digital modes keep evolving rapidly, so it's a lot easier to use a PC to develop and distribute software than having it in some form that only works in a particular make and model transceiver. Seems like the transceiver makers are just now getting around to having the higher-end models able to decode and display RTTY. That isn't a feature I would pay for, because I do lots of digital modes, and because I would imagine those that run in a PC might do a better job of decoding than something built into the transceiver. The PC software gets lots of user experience and frequent updates until it is more or less optimized. You don't get that with something built into the transceiver. Not to say that you don't have a legitimate wish for a highly portable PSK station. Just that it is unlikely to happen in a commercial product. -- jhhaynes at earthlink dot net
