Hi all
Back when I had just assembled my K3 (that was in January, has it been that
long? Time sure flies when you're having fun, hi) I had my Proset Plus
connected to the K3 using a standard Kenwood adapter (the one with a red
marking). Only after a few minutes did I realize that I had forgotten to
turn off the bias voltage. No harm was done however and everything is still
working FB to this day.
Hope this helps

This only a guess but I wonder if Heil pulled a trick with the short red
adaptor destined for use on the K2/K3. Maybe they did a wiring switch in
the adaptor to make it compatible. I remember, the "standard" mike wiring
for the K2 is the Kenwood standard, although, other configurations could be
chosen when the mike connector was wired during construction. I remember
wiring my K2/100 for the Kenwood standard and everything worked. I used
the
Elecraft supplied Heil hand mike which is an electret.
Heil told me that their dynamic mikes would work fine with the K3 and
Kenwood cable. They also said that it made no difference whether the rig
bias was on or off because they used a resistor to block the unneeded bias
which would also protect the rig. I intend to try my Gold line and PR 40
mikes in the future with the K3 using a Kenwood cable but with no bias just
to be sure! However, electret mikes such as the Proset are another kettle
of fish. All I really know is the red adaptor which came with the Elecraft
supplied Proset works fine with the K3. Perhaps it would be worthwhile to
give Heil a call for a better explanation.
The Red banded mike cords from Heil are for Kenwood rigs. I've used the
Pro-Set
Plus! and GoldLine both with KWD and Yaesu rigs. The Yaesu cords are Yellow
banded.
