[Elecraft] RTTY issue (OT?)

Rich, Jamie,

Many thanks, all good now.
It was AFSK A, just got confused as after exiting the menu it says DATA 
on the screen.

Of course it was (insert favourite name of some obscure person from 
history) law that I found out about NET shortly after posting. I guess I 
never needed that in the past as I had always used FSK. Will look into 
doing that with the K3 in future I think.

I now have it set at 915Hz as that sounds even better when trying to 
tune by ear. I'm not sure if there are any downsides to using lower 
tones but it does seem easier on the ears and to tune by.

Is there a way to set it to default to that? Honestly I've never dug 
that far into MMTTY. I'd like to set that up as part of my profile if it 
can be made to work that way.

Thanks
Martin, HS0ZED
