Sorry Dick,
my posting was not exact enough. The radio is able to correct the mark
frequency offset only if you operate FSK (mode selector = RTTY)!!
73 + 55

I think you are correct that the FT-1000MP has a built-in offset;
however,
the Kenwood TS-570 does not. I have a TS-570S(G) and I have have
subtract
2125 Hz from the display reading to get the MARK freq when operating in
AFSK
mode.
