One general note for those starting out with PSK and digital modes: never
run any ALC - as soon as you do the signal starts to get very wide and can
actually be more difficult to copy. I write this as a developer of PSK31 and
other non-released digital mode software.
The IMD gets worse and the software has more problems copying the signal. A
cleaner signal is much easier to decode than a slightly bad strong one.
If you want to see bad signals just look for guys who are over-driving and /
or not using isolating transformers. I've seen really bad signals from
over-driven FT-817's. If you see a PSK31 signal repeated every 50Hz or 60Hz
it's due to lack of isolating transformers.
Old hands will know this.
