| Hi, Garry.
|
| The microphone connector pinout is shown on page 13 of the K3 Owner's
| manual. The index topic is "Front Panel Connectors".  Here is the
| description from the owner's manual:
|
| 1 Mic audio, low-Z (~600 ohms)
| 2 PTT
| 3 DOWN button*
| 4 UP button*
| 5 FUNCTION button*
| 6 8V (10 mA max)
| 7, 8 Ground
|
| I don't own the microphone you mention, but some of the pins appear to 
be
| connected as expected, but I'm not sure about pin 6, which is "Rev 
Audio" on
| the MC-60 microphone connection layout I found.
|
| The MC-60 is a "dynamic" microphone, and you probably want bias off for 
that
| sort of microphone.
|
| As for amplifier switching, it depends on what kind of amplifier you 
have.
| The K3's Key Out line is described on page 17 of the owner's manual. The 
Key
| Out line is specified to switch up to 200V DC at up to 5 Amps, so maybe 
your
| AmpKeyer isn't required if your amp's T/R relay switching line is within
| these limits.

| Ordered Dec 23 received June 4.
|
| I very much enjoyed the build and really like the rig but I am having
| some issues with the setup.  I cannot even find a mic pinout in the
| manual.  Wow, that would seem to be pretty basic information to be
| included.  I do have an MC-60 which is supposed to be pin for pin
| compatable with the K3 but I cannot get much output swing on the
| meter.  I know the PA is working because I have tried it in CW and
| lots of output on CW but the out put is low on SSB
|
| I know others have had issues with this but I don't seem to find any
| solutions in the archhives.  I wonder if someone with an MC-60 that
| has successfully set the rig up could please email me and perhaps
| compare notes? I would sure appreciate it.  My emails should show up
| at the beginning of this post.  If not I can post it on here.
|
| Also.  I'm wondering what to use to key the amp.  I have an Ampkeyer
| for interface.  Does a guy just use the switchable 12 volts for that?
|
| Thanks in advance.
