Of course it makes a difference.  If your AFSK is LSB, SPACE should be
170 Hz *higher* than MARK.  If your AFSK is USB, SPACE should be 170 Hz
*lower* than MARK.

With a MARK of 915 Hz, it sounds as if you are using a K3 in AFSK A
mode.  The normal sideband for the K3 in AFSK is LSB so your SPACE
would be 1085 Hz.

Hi Guys,


I'm setting up 2Tone for the first time.  It appears to be working
though I haven't made any Qso's yet.


In MMTTY I set the Mark to 915 as I like listening to the lower pitch
tones.  When using 2Tone, if I set the Mark down to 915, then what
setting should I use for Space?  (or doesn't it make a difference)


If my visitors leave before the NA Sprint is over tonight, I hope to
get on for awhile pass out some points and try out 2Tone for the
first time.


Please contact me off the list so I get your message faster!


Thanks & 73,


Dick- K9OM
