The default 'HF-Fax' is what you want.
OK I shall take your word that you are not a total dunce and lazy... not that it matters
So.... some questions....
Where are you? do you have a boat? do you have a radio
, if not - why not??
Why do you want to know this stuff? Do you have security
clearance.... can't just share this knowledge with anyone you know...
Do you plan to get a radio
You will find life easier if you have a radio although I did get that us.archive file working here on the Mac.
shots.... Cocoamodem on the left ( using 'line out' from the radio), JVComm on the dark side of my Mac simply using the mic. First one is after the event...second one during next transmission
OK so I'm just showing off but you should be able to get results like this....maybe with a bit more noise...depending on where you are.
