[Elecraft] [K3] RTTY digital setup issue

[Keith Heimbold]

Recently I switched to a new MicroHam microkeyer 2 from the USB 3 product and have had some issues with DM780 transmitting solid RTTY signals with accuracy from my K3. 

It appears that when in Data A mode on the K3 my RTTY transmission is putting erroneous characters in place of the ones I want transmitted. For example, a recent RTTY contact on 20m with PT0S had them copying me as AC6ZZ instead of AK6ZZ. I tried continuing to transmit my correct callsign but they read it incorrectly a few time after initial contact and now I have this error permanently in their log (good thing I have another verified contact with them).  This issue with RTTY has now happened on multiple occasions with other stations and I am perplexed.  

I am not sure if this is a MicroHam issue with the microkeyer 2 or a K3 issue or a Dm780 issue though with the USB 3 I had zero issue with RTTY and DM780 so I am wondering if I have a configuration issue with the MicroHam MK2 setup or have my K3 in wrong digital mode.

Any help from this group would be very welcome.
