This appears to be a problem associated with the backend code in hamlib
for the K2. I checked on both 1.2.7 and 1.2.8 (most recent) library
souce for the K2 and there is no listing for a RTTYR. That means that
hamlib is still reporting the sideband as LSB for both RTTY and RTTYR.
Perhaps the developer for the K2 backend might help us to sort this out.
You can resolve your problem if you use the rigCAT control method for
the rig. The posted K2.xml CAT definition file for the K2 was written
by one of the fldigi developers, Leigh, WA5ZNU. It provides the proper
sideband relationship for RTTY and RTTYR.
If you really want to revert to 3.03 that is available on the Berlios
archives for fldigi.
This link is available also on the www.w1hkj.com page for the fldigi
Hope this helps to resolve the RTTYR problem.

Confirmed by the developers and test team. A fix will be applied to 3.11.
