Today I discovered the FLdigi program which is a swiss army knife of digital modes. Formerly I was resigned to running ham software only on Windows which was a depressing prospect. Now I look forward to using this along with Klog or Xlog to do some digital contesting!

I have a RigBlaster Plug and Play for keying and ptt control on my Icom IC-735 rig as well as a simple looking USB rig control cable that works perfectly well with hamlib.

I have so far managed to tune CW and watch Fldigi decode it successfully, and Fldigi can activate PTT on my rig but it seems it is designed to send an audio signal directly to the sound input on the rig rather than through a keyer like the RigBlaster. What I need to get it to do is to activate RTS for PTT and use DTR for keying CW instead. While a few searches on the related Yahoo groups for this software indicated that such support may exist I have not been able to find out how to activate it as yet.
