FW: WG4S: RE: Anyone know how an MH2 works?

Dan Barker
Well, the Heil Hospital page is for returning (at $12 or more) for them to
repair. I couldn't find any parts on the site - It says to call them if it's
not listed. Of course, they don't answer (actually, it's been busy for quite
some time).

The RatShack 270-090 sure looks identical. I'll just run that.

Thanks for the voltages. Now I know the old element was toast.

Hi Dan,

You might have a bad mic or mic connector or cable problem.

The electret element in the MH2 draws very little current, so it should not
load the 5V on the AF wire but slightly. I see about 1.7K to 1.5K to ground
between mic pins 1 and 7 on two different MH2 mics I have here.

On my KSB2, P1-5 has 5.0VDC without the MH2 connected, and 4.0VDC with it
plugged in.

Heil handles QC problems with their mics directly. If you need a replacement
MH2, go to his website and fill out the Heil Hospital form and he'll take
care of it asap.

Can't believe I've stumpped the list<g>. Actually, I just got impatient.
Does it look to you as if I need a new element? I'm not familiar with
condenser elements but mine appears to be a dead short.

Mine doesn't.

I NEVER use SSB, but I'm sure I tested the MH2 when I built my KPSK2 ssb
adapter.

Anyhow, at pin5 of the KSB2, no mic, I have 5v (10K pull up). With the mic
plugged in, it's 0v. Is that right?

Pulled the mic apart. No shorts, all lines ring out. The element looks to my
DMM to be a dead short. Is that right?

Millampmeter inline with a 11K pull-up and a 9v battery shows .7 ma. Is that
right?

Oh, yes. Whistling into it makes no wiggles on the o'scope.

Dan / WG4S / K2 #2456

Is there a K3 coming

johnny-52
Hi,

I have received a message from my friend in Singapore that K3 is coming.  He
even saw the proto type.  Is it true? Any information releasable to us?

Hi Johnny,

He must be dreaming :-) That would be impossible since a K3 prototype
does not exist. And I would know. Also, we do not have any operations in
Singapore or anywhere else in Asia..

We are always working on potential new products in the lab, but I
certainly do not see another main HF rig in the near term. The K2 is
still our premier offering.

   You've got it wrong.  I've got the K3 prototype right here, but I'm
not letting you see it.

Oh, no. We already have a K9. She barks at the mailman, sits in my lap
and is real cute. She really helped out when I was debugging KRC
code...

Hi Eric,

Thank you very much for your informative advice.

Although I fully apprecipate the great performance of K2, this nice small
rig seems not very popular in Hong Kong.  Perhaps, local hams are just
interested in multi-function rigs instead of high performance one.  I would
just wonder whether there are hams from Mainland China in this reflector who
can advise K2's presence in PRC.
