Thank You very much, I use at cabin and the Scout does work well. I will let
you know it works out and thanks again for the info. 73

Subject: Re: [TenTec] Adapting a Kenwood mic to Ten Tec Scout
OK, Jim,
Best for you to make two columns of pin numbers. Make first col. the MC
50 kenwood list of 1 to 4. Then the next column are the pins to use on
the Ten Tec Scout connector. What I did for a similar case was to buy
an inline female connector, and cross wire it with Scout mail connector.
That way, you keep the Scout standard Ten Tec Scout. you can use
short hookup wire of a couple of inches or even a four conductor
shielded cable if you have it. The shield won't connect anywhere in
this adapter.
MC 50 Scout
1 mic hi goes to 1 mic hi
2 PTT goes to 2 (gnd)
3 PTT hi to 3 PPT Scout
4 mic lo goes to 2 (gnd.)
This scheme keeps like pins together as much as possible.
It appears that the MC 50 has floating pins for separate mic and PTT
lines, but Ten Tec Scout only uses 3 wires as above, ground is shared
with low side of mike and one side of the PTT line.
The mike I have adapted is at home, and I will have to check this with
it. But, this is they way it would be done if your pin numbers and
functions are in agreement with my Scout manual.
It is good to make a drawing of the above chart connections to help you
visualize. Also, be aware the numbering of the connectors may be
clockwise on one and counterclockwise on the other. There are small
numbers molded next to the pins on the solder side, as I recall the
Scout four pin connector. (four pins only because they bring out
voltage for other uses).
If the MC 50 is that desk mike with PTT base buttons; be aware it is a
dual impedance mike. The plug at the back of the base is NOT keyed.
It must be plugged in so as to align one of tow color dots with a silver
raised bar, to select either low impedance or high impedance. Otherwise
your audio will be down 6 dB.
I have run high impedance high output mics like the unamplified D104
crystal mike on my Scout. But, I forget if the Scout was rated as
taking a high or low impedance mike, but the hand mike used with it from
another Ten Tec is probably low impedance.
