[1000mp] IM due to tuner in MkV

[Mike Schatzberg]

Unless the tuner has been modified, it is not in the signal path for the 
receiver, only in the RF output path for the transmitter.

There really isn't enough information here to say more, but you might want 
to try a reset to see if things work a bit better.  There might have been 
some changes from the factory defaults.

73 and Happy DXing,
