Wayne,
Very good! For the record the K3 ACC output be mapped to the
Yaesu "Band data" Jack as follows:
Function K3 Yaesu
DB15HD DIN8/262
------------------------------------------------------
+13 n/a 1
TX Gnd 10 2
Ground 5,12 3
Band A 13 4
Band B 3 5
Band C 9 6
Band D 14 7
Inhibit/~Enable 7 8 (low to tx)
Note: unless the pin 7 of the K3 ACC connector includes an internal
pull-up, it will be necessary to provide an external pull-up (10K
to +5V (max) source).
This should be useful for the large number of accessories (both
commercial and home built) that are compatible with the Yaesu
"Band Data" interface.
Any progress on an input that places the K3 into low power transmit
(programmable level) for setting a RF activated remote tuner or
amplifier/tuner like the Quadra, PW1, etc.?
73,
... Joe, W4TV
