[GreenKeys] RTTY QSO

[Nick England]

Just a reminder that those of us running military gear can generally only
put our "carrier" frequency on even kHz.
Our RATT tones are 2000Hz +/- 85 Hz with mark low. Some gear can only run
USB mark low, so that is inverted from normal ham use..So I can run 7084
USB with mark 7085.915 and space 7086.085

Some but not all equipment can run RATT on LSB (or USB with inverted
mark/space) but still only on even kHz +/-85 Hz.
You folks with "modern" radios will have to accommodate us because we can't
transmit/receive on an arbitrary frequency.

Getting into RTTY recently, one of the things I have found most frustrating
is the seemingly random (or perhaps intentionally awful) selection of
mark/space frequencies that has evolved. YMMV.

Cheers,
