Hi All,
I'm a new K3 owner so please be gentle.
I'm not a great SSB user so I want to use my cheap PC gaming/Skype
headset on the odd occasions I use sideband. It has separate 3.5mm plugs
for headphones and microphone so the K3's rear panel jacks seem the
obvious place for connection.
The
The MIC SEL menu item chooses between the front panel and rear panel mic jacks.
I'd review the settings for that.

Just don't worry about it. It'll work just fine. Follow direction in manual
to set levels and be sure 'rPL bias' is selected for mic. I have used the
Yamaha CM500 as well as a common Creative Labs 'desk' mic with my K3. All work
well.

Alan,
The rear mic jack is a mono, not stereo, jack. It will short the ring and
sleeve together. Audio is on the tip, as is the voltage. The mic should
have a blocking capacitor to isolate the audio from the voltage.
This is standard for every radio I have owned. If a stereo jack is
Alan,
In most cases, the tip and ring of computer microphones are connected
together. I don't know the particulars of your headset, but yours may
be different.
Yes, the K3 applies bias to the tip contact. It works with most
microphones that way.
You may have to modify the plug on that

Pretty sure that's not true. I believe that the connector is a TRS
type, but the ring is not connected to anything. The schematic for

As Iain has noted, this is incorrect. It's a TRS jack that uses only the
tip and sleeve contacts.

Right.

Hello again. Thanks to so many people for their detailed help and
suggestions. I seem to have solved the problem.
First: yes, Don is correct, this Plantronics headset microphone has tip
and ring connected together, just like every other PC headset on the
planet. That means my laptop offering
I believe the theory behind PC microphone connections is that the same
connector will work for both dynamic and electret microphones. Dynamic
microphones use mono plugs, which short the bias. That isn't a
problem as the bias is not a voltage source - it is actually the
drain(?) load on the
That statement is only applicable to the actual electret element itself
which has very low output. There are very few bare electret elements
available in the marketplace.
Practical implementation of the electret element uses a built-in
amplifier inside the package that is normally sold as an
