Mine tunes with the internal tuner on the carolina windom no problem.
So as john says, it depends on the antenna for sure.
Now weather my windom actually radiates much of anything on 5.3MHZ is 
another matter entirely hi.
The ts2000 tuner will work on any frequency between 1.8 and 29.7MHZ as long 
as the swr is 3 to 1 or less...
I suspect if you have an antenna that works well on 30meters, then you could 
probably tune for 60M due to the harmonics...just like 80M, 40M, 20M and 10M 
etc.

Personally, I've never heard a single voice transmission on the alocated 60M 
channels.
Perhaps now that the regs have been loosened a bit, more hams will give it a 
shot.
