Hi Tom,

The 910 is probably different than the 821, but for 821 owners just pull J7 
on the
RXA board.  It is on the top LH rear of the 821.  I cut a small hole in the 
top cover
and now I can easily re-enable the 144 xmit  in seconds, should I desire.

I've been struggling for months now swapping cables to keep from frying my 
converter,
but now my worries are over...Should the need to swap U and V xmit 
frequently, develop, I'm sure
there is a way to interrupt a voltage with an external switch, and do the 
same thing.
Perhaps some Icom 821 owner has already figured this out....

I had to go to ICOM Japan to get the answer, I wouldn't bother with ICOM 
USA, I can never
get an answer from them.

They answered my question the next day...IF, and that's a big IF,  should I 
ever want another
ICOM I'll order it directly from Japan!!
