[Elecraft] RTTY issue (OT?)

[Richard Ferch]

I'm not sure why you are using DATA A instead of AFSK A, but ...

If you don't want MMTTY to transmit on a different frequency from your
receive frequency, turn NET on - in AFSK, that will force the TX to follow
the RX. Also, you should tell MMTTY that your preferred frequency is 1275
Hz. To do this, set your HAM default to 1275.

A general rule for AFSK is: while S&P, turn NET on and AFC off; while
CQing, turn NET off and either turn AFC on or leave AFC off and use RIT
instead for off-frequency callers. Some software will switch the NET and
AfC settings for you automatically between run and S&P modes.

If you do use AFSK A instead of DATA A, you will have to change the K3's
PITCH setting to 1275-170 from the default 2125-170.
