It has worked for me.  When AO-51 is in  V/S mode, I have to use a 
seperate radio for the downlink.  In my case, the K5GNA converter is set 
for 2 meter IF and that is fed to either a handheld or an ICOM 706MKIIG. 
  I let my IC-910H perform the uplink duties.  That may be overkill but 
that is my primary satellite rig when operating at home.

I probably am the only one it affected since I have a different down converter set up than most. I use one of K5GNA converters with the original LO crystal. I convert the 123.2 Mhz IF to 29.2 Mhz. I have examined all the obvious harmonic/image/IF combinations but haven't hit on anything I think should be a problem.
