Garey,
 
The T-4XC manual indicates that if you use a 21.1 MHz crystal, the =
usable=20
freq is 10.25 - 10.5 MHz. The column that says "Do Not Use Between" is=20
blank.
 
I would like to add 30 meters and possibly 17 also, but it seems to =

few caveats.

  -There is a very good reason for using the 20.8 MHz crystal =
instead of=20
  the 21.1. There are several spurious outputs in and around 10 MHz =
when=20
  using the 21.1. This is specified in the T-4X(any) manual with "do =
not=20
  use" ranges for certain crystals. Keep in mind that the PTO =
operates in=20
  and around 5 MHz.....And yes, you can transceive on any =
crystal you=20
  have in the receiver, but the same problems occur with a 21.1 MHz =
crystal=20
  in the R-4(any). If you just want to listen to 10.1 - 10.150 the =
21.1 MHz=20
  crystal will work in the receiver. But don't transceive using that =

  crystal. Transceive isn't all that satisfactory on CW anyway, =
since the=20
  offset is around 900 Hz and most f! olks like to listen to CW at a =
