Wayne et al.

I am surveying various rigs to see what their microphone input impedance
values might be.

I note the K3 schematics show just about every audio path including the
microphone's path terminated in 10k ohms or so.

In the KSB2 I see 1k ohm (or 180 ohms if /ATTEN is asserted).

Was there a compelling reason for having different termination values, 10k
vs. 1k, between transceiver model lines?

Thanks.

John
