[MRCA] WTB BC-459-A *Update*

Of course no one in their right mind would "want" to have to replace any of 
the trimmers.  But if you find that you must, I have I think some of all of 
them, NOS.  ID'ing them isn't simple so if you find that you must replace 
one or more, contact me first before you start removing a stick from the 
transmitter.

One other thing about the subject transmitter.  Most hams seem to think 
that the conversion from whatever to T-412 consists of just unplugging the 
blanking panel or LFO and plugging in the Gables Engineering CDA-T module.  That 
isn't the half of it.  The simple check to confirm that it is actually a 
T-412 is to remove the transmitter top cover and confirm that the LOCAL-REMOTE 
switch has two switch wafers instead of the original one.  I would do this 
even if the rig has a T-412/ART-13B nameplate.
