[digitalradio] Digital Modes Presentation (Need Help)

[Alan Wilson]

Hello, I just recently got back into digital modes. I last used it in 
the 80's with Packet. Of course I got asked to do a presentation at our 
next club meeting. What I need is some suggestions about where to find 
information that I can pass on to other hams who know little about PSK 
and other modes. Any help would be appreciated very much...73, es 
thanks, Alan
