I feel the need to bring this problem to the top again: is Sam ever
going to change that terrible channel selector?

I'm not going to buy another S-series until he does.

I really really really want to get the S9-175 when it comes out, but
as bad as I want it, that channel selector is enough of a deterrent to
stop me from buying it.

it 'feels' different then most channel selectors because it is different. it is not fully mechanical in the way most are, but partly electronic. theoretically, changing channels could be done with a push-button.

yes Pat is correct. Change the 4 pin mic jack to 6 pin. The wiring is available online.
Get yourself a mic from a 2950 or simular.
Now you can change channels from the mic.

Well, Pat and Wankle, you are right, Here is a response that I just got from Sam Lewis:
----------------------------
Good afternoon
The radios are MCU controlled and the frequency selector is call a "shafted encoder". Encoders are not switches, you can actually rock the encoder back and forth without changing position and change the frequency. A pulse of energy actually sends a message to the computer and commands the frequency change.

The detent on an encoder is not as "stiff" as a detent on a mechanical switch, that is a fact of life.

There is an alternative if you are interested. For between $75.00 and $90 the addition of a scanning mike can be implemented. In fact, Chris Holland who is our lead technician on the S-9 175, advises he could install the scan feature on an RK 56 or similar aftermarket mike.

Thank you
Sam Lewis

Oh yeah! I agree. The next Magnum I get will DEFINATELY have that feature added to an RK-56 :-) The bumpety-bump in the ol' KW won't be a problem any more!

Hey Guys, you can actually do this one yourself.
Its only 3 wires.
SW200 is what you are looking for, the board the channel selector is mounted to.
Get yourself an RCI microphone and matching mic jack.
The 3 wires for channel UP DOWN and Ground.
Porkchop there is no reason to do the Mosfet swap if your 2sc1969's are working find.
The Mosfets work in a very small window between destruction and linear operation.
