Let me clarify some issues before leaving this subject.
1) There are apparently multiple versions of the manual that show different
KAT500 power requirements. The current one, Rev C, states on page 2 that the
voltage should be 11 to 15 VDC at a current of 1.0 A max (200 mA typical).
2) A modified K3 will output 1.0 A. See *K312MDKT.
3) *After further digging I see the warning that if the K3 and KAT500 are
interconnected via the AUX bus, the KAT500 must be power before the K3 is or
*the K3* won't initialize properly. (p 14) So there is my integration/timing
issue. Imagine having to have your printer powered up before booting your
computer to avoid latch-up. Does this mean that other peripherals (KRC-2)
hanging on the AUX Bus will have the same effect?
4) On a positive note, it went together nicely (not too pleased with the paint
on the top cover) and seems to work fine using just the K3 without
interconnects, just r-f sensing. The clattering relays are a little frightening
though when my only prior experience with autotuners was the quiet whirring of
the motors in my TS-870SAT.
