As a lot, I would think adding computer control to handle full doppler would not be that big a deal nowadays as most of the programs support it. I am not telling you how to spend your money though. The big test will be at Field Day when I am using full doppler and listening to everyone do the doppler-shuffle. :)\n\nSee you on the air as W4TA from Field Day but NEVER on an FM bird. \n\n73,\n\n\nTom Schaefer, NY4I\[email protected]\nEL88pb \nMonitoring EchoLink node KJ4FEC-L 489389\nDSTAR Capable APRS: NY4I-15\n\n\n\nOn Jun 9, 2011, at 1:19 PM, David Palmer KB5WIA wrote:\n\n> Jerry's correct.
