The amplifier port on the Y-BOX v.2.1 (labeled "To AMP AUX") normally has
no connection on pins 1, 4, 6, 7, and 8.  The AUX port on the Amplifier
uses these pins for special purposes not related to the K3, as documented
in amplifier manuals.  For example, pin 1 and pin 6 on the amp. are used
with Icom radios to get Band Data.  Pin 7 can be connected to an audio
alarm (drives low for fault).

Using a standalone Y-BOX connected to the amplifier AUX with a 15-pin M/F
cable, you can "break out" these special pins to any of the four RCA ports,
making it easier to connect non-Elecraft devices to an Elecraft amp.

The four "unmodified" jacks on the Y-BOX v1.3 could be used with:

   1. KPAK3AUX cable (to an amp)
   2. Remote Rig cable
   3. microHAM MK2R+ SO2R box
   4. Top Ten Band Decoder / Antenna switch

(Since none of these cables wire all 15 pins; connecting them all in
parallel works fine).
