I tried a RS electret element I have here and the audio is distorted and weak
- do I have a bad element or am I doing something wrong? I wired the
element directly to the mic wires bypassing the transformer in the mic with
no cap or resistor. The red wire and audio to pin 1 and the ground to
Are you saying that you connected 2 wires to pin 1? There normally
should only be one wire to pin 1, and that is the AF line which should
connect the other end direct to the + side of the electret element. The
other side of the electret element must connect to ground (pin 7 or pin 8).
Turn
Forgive me for being dense about this! The RS element has a red wire that is
the V+ for the element. The other wire is the shielded audio output wire.
Because the K# has switchable voltage available at pin 1 and from what Lyle
posted I assume a coupling capacitor (which allows both V+ and audio
You are correct that with a 3 lead electret - the V+ and the AF should
both be corrected to pin 1. The remaining pin of the mic element should
connect to pin 7 or pin 8.
Many electret elements only have 2 leads and must obtain the bias
voltage through the AF line, apparently the one you have
lead. The K3 applies the bias
based on the internal settings you make through the menu.

I want to replace the element in a Kenwood MC-50 with an electret. I know
that the K3 provides bias voltage to pin 1 on the front mic connector which
is also the audio line - as long as bias is selected in the mic sel menu.
Does this pin already have the coupling capacitor in line or do I need

Yes.
73,
I just finished completing my K2 # 4998 wonder what type of hand or mobile
mic I should use?

I just purchased the Heil Proset-K2 Headset for my K2, primarily for portable
use. When back in the shack, I would prefer a desktop microphone and speakers
... so ... since the microphone jack apparently needs to be customized for the
specific microphone, how am i going to be able to swtich
The MD2 from Elecraft is wired the same as the Proset-K2, no
adjustment necessary when switching between them.
