In my experience, CPU load during transmitting is usually equal to, or some moderate amount less than the load during receiving. I don't recall ever having seen the CPU demand of transmitting be higher. > Perhaps 'PSK31', 'MFSK', or 'gMFSK' implies ,MT63'. > However I do not recall them being mentioned in the original message > or attachment. In my experience, PSK31 and MFSK have CPU demands similar to MT63. I just tested MT63 specifically on my P233 laptop, using the version built into the gMFSK program. Both transmission and reception seem to use 20-25% of the CPU horsepower (apparently split between the audio processing and the UI). I'd guess that even a Pentium 100 might handle this modulation without overloading, although that'd be running a bit close to the limits. > I am still missing software requirements; > kernel version, gcc, utilities, tools, ... For one example: I'm running Debian Linux ("testing" distribution), gcc 3.3.4, on a 2.4.20 kernel. >From what I've seen, a good percentage of the ham-radio-related software packages for Linux make use of GNU autoconf, and seem to be quite adaptable and forgiving about compiler versions, library versions, and so forth. You have to meet the prerequisites of any given project, of course (e.g. you may need a standard FFT library, or a UI toolkit, or etc). > Is 'MT63' a development project or is it really ready for > 'user' deployment? i.e. Is it 'alpha', 'beta', or > stable release? Can't speak for the author on that one, sorry. The MT63 code compiled into gMFSK seems to work, although I haven't tried to make any QSOs with it yet.
