The transmitter gain of the K2 is definitely not uniform, but different on
every band. This is problematic when trying to run digital modes, where the
audio input needs to be adjusted on every band.
I wonder if you have lower gain on 20m because you have a transmitter alignment

Ed,
Instead of trying different microphones, I suggest you modify the KSB2
option board to reduce the bass response.
Change C34 to a 0.47uF electrolytic capacitor and C32 to something in
the range of .0043uF to .0056uF and you will reduce the bass response
significantly. Those are values re
Search eBay for a NOS Turner JM+2/U hand mic. Do not adjust it to obnoxious
levels and it will sound absolutely wonderful. If the possibility of an old
curmudgeon or two taunting you over using a "CB" mic is of concern, tell
them you're using an Icom HM-36 and have a private laugh at their expense
Steve,
The K2 can be configured to use several different microphones.
You will have to examine the microphone configuration header on the back
of the front panel to determine which microphone that K2 is set up to
use. See the KSB2 manual for how it can be wired for the various
microphones.
Out of the box all pins on the microphone connector are open circuit.
There is an internal jumper block that has bias free microphone audio
and resistor free 5 volts on it. If you are seeing 5 volts on pin one
on the external connector it is because someone has wired 5v to it.

Unfortunately, the mic plug wiring is different than that for the MH2.

If so, replace the adapter with the one used for Kenwood (red band).

Whether you can use those jumpers or not will depend on the wiring of
the microphone plug.
If it has AF on pin 1, PTT on pin 2, and the return paths on pins 7 and
8, then you can use those little computer type jumpers - otherwise you
will have to wire them.
If you need to use wire, one

Look for a junk computer, computer motherboard, or computer plug-in

Yes, that is normal. BUT you can stop it and ground the shell of the

The mic audio in the speaker is definitely not normal. That says you

First question is - did you remove the KSB2 board during the K60XV

Paul,
Do 2 things.
Yes, connect straight across the microphone configuration header to
connect +5V to pin 6, and then solder a 5.6 k resistor between pins 1
and 6 of the mic jack.
Second thing is just a check of the Heil Kenwood adapter - use your
ohmmeter, connect one lead to pin 6 and check

Any of the Heil mics designed for the Icom will work FB with the K2 -

Scott,
Most Icom mics work well with the K2, but you did not specify which ones you

Just follow the mic configuration header wiring shown for your particular

Both HM36 and HM12 work well with my K2. In fact, KSB2 is very
accommodating. It also works well with most Kenwood mics like MC43s. I

Yes, it is going to be hard since you have already cut the cable. It IS

I thought for sure that my K2 came with the mic jack (#370). It's been so
long I can't remember for sure. I did get some plastic hole plugs for the
unused holes on the back panel from a hardware store that snapped in and
worked great until I finished filling them all with accessories.
