Sure. That's fine but they are not mutually-exclusive requirements. Once you have automatic configuration you can always manually configure to limit the number of modes you want to report. Heck, right now I am only interested in two modes, Olivia and Thor, so I know what you mean. And I would like to do that over a very wide swath of spectrum. There was a time when amateur radio depended on the skill of operators. Heck, there was a time when computer networking depended on the skill of the operators. Those of us working on building networks discovered that, with just a little effort, we could automate the configuration process thus bringing huge advances in reliability and usability. Much of amateur radio seems mired in the need to demonstrate arcane skill. Unfortunately it is what has made amateur radio become mostly irrelevant. Think back on the history of amateur radio. Up until the 1960's amateur radio was still at the forefront of RF communications development. Since then, not so much. By the end of the 1980's nothing new was coming out of amateur radio except where a few people were doing research on their own and moving that to the commercial sector. (Parts of the Internet are examples of this.) However, there is a place where amateur radio has the potential to lead the industry. HF communications has been largely ignored by industry as a result of high-bandwidth terrestrial and satellite links. These depend on infrastructure. There are some real advantages to communications systems that are completely independent of established infrastructure. Highly-reliable, self-configuring digital HF links seem to fill that bill. The trick now is to eliminate the arcane skill required to make it work. We actually have a pretty good example of something that works surprisingly well -- PACTOR. If you have used the WinLink or SailMail systems you know what I mean. But there is a LOT of room for improvement in PACTOR and the layers above it. Fldigi represents a springboard for developing something newer, better, and more automatic. Just thinking aloud. -- 73 de Brian, WB6RQN/J79BPL
