[Elecraft] K3 - AFSK A

[Lyle Johnson]

Hello Stewart!

Be sure you use the PITCH control to select the tone pair you desire to 
use. The K3 will then display the RF frequency corresponding to the RTTY 
Mark tone.  As you change pitches, the frequency display won't alter but 
the offset of the radios suppressed carrier will move in accordance with 
the selected PITCH.

If you engage the dual tone RTTY filter, it will be set up for the 
selected PITCH.

Be sure the RTTY program is set to the same pitch.  Some programmes are 
waterfall-based and change the Tx tones to match the Rx tones.  If you 
are using such a program, you may be better off with DATA A, and if you 
want LSB then hold ALT to change sidebands for DATA A so that you see 
the LSB icon. IN thie case of using DATA A, the radio will display the 
suppressed carrier frequency rather than the MARK frequency.
