[Elecraft] [K3] Using NaP3 in AFSK A mode

[Joe Subich, W4TV]

Pete,

PowerSDR had offset values for DIG_L and DIG_U.  They represented the
MARK frequency (2125 for DIG_L and 2295 for DIG_U).  Are those set
correctly in your installation?

Unlike most rigs - except for Yaesu - which do not allow the dial to
show the true RTTY (RF MARK) frequency in AFSK, the K3 AFSK A shows
the RF MARK for AFSK A (it shows RF SPACE for AFSK A REV).  That means
you may need to do some iteration with the NaP3 DIG_L/DIG_U CAT Offset
and the internal PowerSDR DIG_L and DIG_U offsets.  Unfortunately the
developer of NaP3 folded his tent and disappeared so there is no longer
any authoritative support.

73,

    ... Joe, W4TV
