KPA500-KAT500 tuning settings

[ANDY DURBIN]

"Kenwood rigs have master/slave menu options designed to enable one Kenwood
rig to follow the frequency of another.  The KAT500 manual recommends
enabling these options, but I cannot confirm if they affect the frequency
reported by the FA; command.  If you have a null modem cable, can you
please connect it to the TS-590 COM port when these options are enabled,
and report what gets output when SPLIT is ON?"

Bob,

My TS-590S COM port is connected to my controller which has the ability to output a comprehensive set of frequency data to the diagnostic log.  E.g.

125:50:02.165  Log all frequency data
IF00018100000      004000004020010000;FA00018100000;FB00018100500;
VFO A = 18100000
VFO B = 18100500
RIT/XIT =  0040
IF_P4 = 0 (1=RIT active)
IF_P5 = 0 (1=XIT active)
IF_P8 = 0 (1=transmitting)
IF_P10 = 0 (0 = VFO A, 1 = VFO B, 2 = MEM)
IF_P12 = 1 ( 0 = Simplex, 1 = Split)
RX freq = 18100000
TX freq = 18100500
Expected KAT f; = F 18100;

If that data would be useful to you I can run a TS-590S test for the 4 possible combinations of Menu 58 and 59.  I'd prefer not to change my station configuration.  The example shown above is for 58 off and 59 on.  This is the configuration I normally use.

73,
Andy, k3wyc

Why is it obvious?  Actually, I don't. I have a tri-band Yagi that I also tune
for 12 and 17.  So each band has a different tuning solution, which has nothing
to do with a different antenna spigot.  And note I said, "for instance", i.e.
for example.

K3WYC has pointed out the pitfall of relying on r-f switching.
