I cannot comment much on the microphone situation except to say that the
old crystal mics (Astatic and D-104) are high impedance and will need
some type of hi-Z to lo-Z conversion to work with modern transceivers
(K3 included).
As for test equipment for the K3, little is needed - a good 50 ohm dummy
load is a requirement for any hamshack, and you might want to consider
having a DMM around and an RF probe. The K3 itself does not *require*
any test equipment other than that. Look at page 6 of the K3 Kit
Assembly manual for the entire list of tools that may be needed. The RF
probe and a good 50 ohm resistive dummy load can serve instead of the RF
Power meter, and the Elecraft XG1 or XG2 is a good source of the 50 uV
signals that are needed for the S-meter calibration.

Hello,
Does anyone have any experience with this headset and mic for sale on Ebay?

The price is right, but don't know if it is any good. The Heil setup, I'm sure
will do the job. However I would like to look at other options. The only mics
in my shack are Drake 7077 for a TR-7 and a couple of Astatic mics a D-104 and
a 10-D. They work great on tube Collins gear, but I'm not too sure how it will
act on a K3. Any thoughts on the Astatic mics?
I'm coming out of the stone age in a way with a K3 when it gets here. All of my
test equipment is a generation or two newer tham the gear I repair. The K3 will
be my only rig less then 30 plus years old. It will be fun to play with.
