I once had an MC-60 mic, brand new at the time several years ago.  I got
rid of it after about 6 months.  Thought it was the worst mic I ever
owned.  Well, not quite the worst -- but I never did like anything about
it.  Since I am on SSB so rare these days, mostly CW, I just use the stock
K3 hand mic and it works great.

Since I have zero use for VOX, and the idea of a foot switch is a total
anathema to me, the Elecraft MH2 works great.  I might get a couple of
backup MH2 mics just in case mine gets dirty.

I recall checking the MC-60 at Kaiser Permanente's Pasadena Walnut Center
EOC's radio room (as I was re-building it with new furniture, some new
radios) for a common fault with (some of) these.

The mic-element ground was swapped with the mic-hot in the connection in
the mic body. That allowed RF in the shack back into the audio chain,
causing all kindsa trouble, including stuck PTT and ratty audio.

Google [MC-60 Ground] for the relevant articles. (IIRC, ours didn't have
that problem.)

[Elecraft] Toroid Holder from a Clothespin

[Philip Barnes-Roberts WA6DZS]

Just had a call from a prospective client for a K1 build, who was (as 
are many) hesitant about winding the ever-elusive little toroid inductors. 

I lost him as a client when I told him about my little clothespin tool 
for holding the core while winding, and wasn't sorry at all to have 
spoiled that sale, since he's now encouraged to tackle it himself, and 
that helps develop the pool of talent for building, one of the 
(sometimes unstated) goals of kits.

This is a tool I made at JPL, when I had to wind some little inductors 
for our Line Impedance Stabilization Networks [LISNs] in the EMC Lab, 
and have repeated and used for Elecraft building, since the smallest 
cores can be hard on the fingers.

Here's my blog entry about it, with a photo;

Use it in good health, and enjoy!  A warm and happy (building?) holiday 
to all!  3-2-1-melt solder...

The naive know not their mistakes.  -And repeat them.
The foolish blame others for their mistakes.  -And repeat them.
The intelligent profit from their mistakes. 
The wise profit from the mistakes of others.
