The Kenwood MC-90 are a very good desktop microphone who fits directly on the K3 connector without resoldering. It has a wider frequency range than the Heil HC4 or HC5 and gives you a broader range of sound possibilities.
The MC-90 is a 250 ohm dynamic microphone without any amplification, only a 2 step low-cut switch on the bottom of the base. It is the best all-round desktop microphone I have tried, suitable for both full-sounding "ragchew" and DX.

On the MC-90 you can set lowcut to position V2 and have a similar sound. There are 2 replaceble microphone heads, use the one without holes in the side for a bit more treble response. Microphone connector: http://www.universal-radio.com/catalog/mics/1870plug.jpg Since the MC-90 has no connection on pin 5 or pin 6 (+8V) it can be safely used on the K3.
