Hi Barry:

Thanks for your comments.  That is quite an accomplishment to hold both those records!

Just a comment about the IM (..--) prosign used to end the RTTY idle.  It is storable in the memories.
You can do it by using your paddle (entry should end right after sending IM).  Of course, the timing is critical; it must be IM not "I" and then an "M"!  Alternatively, you can use the K3 Utility to easily store CW memories (which will also work in Data modes) and there is a special character to store the IM prosign (the vertical line "|" --- I hope that comes out right in the email).

That is a good suggestion for a menu entry for setting the idle-time.  But in the meantime, IM will work.

Thanks again,

73

John - found your post interesting and timely, as I played around with the CW to RTTY mode last night myself in the contest.  I used to operate the CQWW RTTY contest regularly, and still hold the USA records for SOHP and SOLP, after number of years.  I have a feeling I threw off some of the old-time regulars with my new zone and state :.)  Also, my signal is quite a bit weaker now, running barefoot and stealth wires.  The only issue I had with the CW to RTTY mode was trying to send a - (-....-)  As it's a character I never use in real CW, it was difficult to send correctly.  

Appreciate your post, especially the tip about CONFIG: VFO OFS.  That's one setting I'm going to use.  I didn't know it existed.  Regarding your follow-up post, I don't have a P3 and my K3 is new, and I had no problems.  The only "issue" I had was the long idle time at the end of a buffer.  I tried programming IM (..--) into its own buffer, but it wouldn't "take."  I guess it only accepts real CW characters.  I'd like to see a CONFIG setting for an adjustable end-idle time.
