Larry, Why not measure the current. Break the positive 12 volt Power Supply connection and insert your DMM set to measure current. Then short the keying input line on the relay box. You DMM will tell you how much current is being drawn. A new K3 has a 1 amp rating on the 12 volt output.

Re: [Elecraft] K3 digital mode

Actually either can be used. But using AFSK-A gives you the benefit of still using the K3 dual peak filters for RTTY. You will need to make sure your tones (pitch control) on the K3 match what you use for MMTTY or whatever software you use for RTTY. 73 Greg On Tue, Mar 4, 2014 at 8:18 AM, iai

Hi Mike, If you're using external sound for your data modes, you should have the mode set to DATA A, not AFSK A. Having your audio set to Line in DATA A mode is correct, unless you're going through the mic and phones jacks. Most people use the line in/out for external data modes (very handy!).
