The purpose of the transformer isn't to get anything close to a
conjugate match. Doing so would produce a very inefficient PA, and, I
suspect, would produce unacceptable levels of distortion
(non-linearities in the output impedance would be visible in the signal).
The purpose is reduce the

Except they *DO HAVE* impedance matching - typically a broadband output
transformer (4:1, 9:1, 16:1) to 'get close' followed by some kind of

Joe W4TV and Bob N6TV,
I have been following discussion on the Elecraft and Elecraft K4 groups
about MC-50/MC-60A and dynamic mike bias off (not being off, at times).
I have been using a Kenwood MC-60A with my K4D, I plan on re-wiring my
Heil GoldLine HC-4 taken from TenTec Orion II, and it

The high impedance setting of the MC-50 will have more output but

In the world of audio, impedances have not been matched for half a
century. Only those with blinders working in
I do have the K3 set for high impedance for the MC-50 (tap 1 in the
mic selection menu) and then I switch to low impedance for the
CM-500.
In MENU:MIC SEL, tapping 1 toggles between high gain (dynamic mic) and
low gain (electret mic) input levels.
I tried low impedance with the MC-50 (yes

Digging around I find I have an older Kenwood MC-50 mike in its original box.
Anyone have experience with this?
Is it reasonable to use this with my K3. It is dynamic so no bias. I think
the 600 ohm setting is what I am supposed to use. Do I need to change my
equalization from what I use
