Floyd -- I'd have added this to my earlier post if I'd known you had an 850 to key. The simplest way I know is just plain transistors. Works well. Go to this website for the exact details and pictures. Dick Stevens, N1RCT got this together, and I find it does very well with my 850 and 570DG both. http://www.w5bbr.com/pttfsk.html 73, Jon K1US ----- Original Message ----- From: "Floyd Sense" <sentek@sprintmail.com> To: <writelog@contesting.com> Sent: Friday, October 27, 2000 9:55 PM Subject: [WriteLog] TS-850 FSK connection? >> I've looked at the generic interface for FSK at the writelog.com site.
