Re: [Elecraft] MH2 Microphone issue

[bodel...@juno.com]

I would say a faulty mic. is a very good possibility. I am on #3. The original 
mic worked properly for about 3 months. The "replacement"  did not function at 
all  but #3 seems to play just fine. I feel as though there must have been a 
bad "batch" Other than that issue the K3 and Elecraft's first quality service 
and support can not be beat

I replaced the 5v regulator and the 5v line is now reading 5vdc. The MH2
still does not work. I also plugged in the Pro-Set and the pro-set works
fine. Do you think the microphone could be broken? I have never used it
before so I am not sure it works.

Re: [Elecraft] MH2 Microphone issue

  Yes, it is possible that your MH2 has a problem.
Did you buy it used?  In that case, someone may have re-wired the 
microphone plug for some other radio.

Re: [Elecraft] MH2 Microphone issue

[Don Wilhelm]

  The low voltage is probably your problem.  I would think 3 volts is 
too low for the microphone element.
I know 3 volts is too low for proper operation of the microprocessor, 
and since you have not said anything about other strange symptoms, I 
would first check your voltmeter.  Do you read 5 volts or 3 volts at the 
output terminal of RF Board U8 - it should be 5 volts.  If you read 3 
volts at RF U8, try an different voltmeter.

Is the regulator getting quite warm?  If so, you may have a fault on the 
5 volt line somewhere.  If it is not heating up, the most likely reason 
is a bad regulator.

The 5v regulator U5 on the control board has an output of 3.0v. I
disconnected the front panel from the control panel and the output is still

the microphone?

I also noticed there is an update to grounding the microphone jack. Could

Re: [Elecraft] MH2 Microphone issue

All of the jumpers are installed. I measured the voltage on pins 1 and 6 and
the voltage is approximately 3.1 vdc. I can still use the K2 with the
Pro-Set and it works fine. The MH2 does not work even though the KSB2 manual
says the configuration is the same.

Re: [Elecraft] MH2 Microphone issue

[Don Wilhelm]

  Do you also have a jumper on pin 6 of the microphone configuration 
header?  You can check quickly by measuring for voltage at pin 6 of the 
microphone jack - it should be about 5 volts.  You can check for proper 
soldering of the bias resistor by measuring for a similar voltage at mic 
jack pin 1.

If your Heil ProSet uses a dynamic element, you may (or may not) be able 
to use it with the bias resistor in place.  If there is no DC blocking 
capacitor, the mic element may "sound funny" due to the DC current 
through it.  The Elecraft/Heil Proset-K2 uses an electret element, and 
the Heil ProSet-iC (Icom) does too (and those need bias), but as far as 
I know, the others use a dynamic element.

Re: [Elecraft] MH2 Microphone Issue

[Stephen Prior]

Jeff

At the suggestion of Ian GM3SEK, I removed the spring under the ptt and cut
a bit off it before stretching back to its original length.  It was a bit
fiddly but not difficult.  Dropped it more than once!

The ptt is now much easier to use but as others have remarked, it has no
positive tactile feedback - it needs a click or similar. A shame, since the
quality of the audio is very good, although my voice prefers the MD2.

Re: [Elecraft] MH2 Microphone Issue

[Mike]

Well durn! I saw that kit, but it didn't say which element it was. 
There's no way to order from their website either AFAICT. I needed some 
of the foam pads that go inside the Pro-Set ear muffs, and had to do a 
phone order. I now have the CM-500 on the K3 and the Pr0-Set on the 
backup PRO II.

So the real downside of dealing with Elecraft is we can so easily get 
used to great customer service. :-P

Yes.  Heil will no longer sell the "bare" elements.  One must
purchase a D-104 upgrade kit in order to get the element.  In
addition, Heil will not sell replacement "clamshells" for the
original Proset mic boom for repair purposes.

In spite of their claims, Heil do not care about "customer
service."   The cost to repair a damaged ProSet is more than
replacing it with a Yamaha CM-500 and the ProSet would have
to be shipped to Heil rather than allow the user to make a
relatively simple change of mic element and housing.

Hi Paul

What are your mods? Did  you just use a capacitor to roll off the bass?

Someone once told me that the Heil HC5 is sound transducer that was very common 
on PC motherboards. I lost the web link of the manufacturer, which is a pity  
since the HC5 seems to produce good audio on just about every radio that I have 
used. The only problem is that you cant buy the HC5 cartridge anymore.

Re: [Elecraft] MH2 Microphone Issue

[juergen]

Hi Jeff

The button is a bit "mushy" lacking a positive action. 

Another problem that I have with the MH2 is its  curly cord. The curly cord is 
so stiff that it pulls the radio if you try and stretch it a bit. It just does 
not have enough stretch, even if pulled a small amount.

I like using a hand mic. What I suggest you do is try and getting an original 
Icom HM36 hand mic. This Icom mic sounds pretty good on the K3. It has a nice 
soft curly cord and the button has a nice positive smooth micro switch click.  
The current model HM36 is junk made in China, try and get an original Japanese 
made HM36 that came with the early Icom radios.  Just make sure you throw the 
Icom radio in the bin and keep the mic!

G'day everyone!

First of all, 
After having given my K3 its first HF hitout this last weekend for our (Myself 
- VK4BOF, Gary - VK4FD & Dale - VK4DMC) mini dxpedition for the World Flora & 
Fauna at Undara Lava Tubes National Park in North Queensland, Australia I must 
say that I am more than impressed with my new K3.

It performed flawlessly and was a real pleasure to use, the MH2 microphone is 
however another matter.

Whilst its transmitted audio quality is excellent it appears that you must be a 
400lb gorilla to use the damned thing, the TX button is so stiff to use. :-)

And even when you get the button in, it must be only barely making contact that 
as soon as you relieve any pressure at all from the button, the radio goes back 
to RX mode.

Does anyone else have this issue?

Re: [Elecraft] MH2 Microphone Issue

The MH2 mic PTT  may be getting caught in the
rubber surround. It is easy to undo the cover.
Note that the PTT button only fits one-way, there
is a cut away slide which fits onto the switch.

For my own use the mic insert had a tad
to much bass, it has been slightly modded here to
suit.

Re: [Elecraft] MH2 Microphone Issue

[David Herring, K6DCH]

Jeff

The button on my MH2 is certainly stiff.  But mine seems to be a bit  
more forgiving in the PTT department than you've described yours to  
be.  I don't have to remain totally clamped down on it for the rig to  
stay in transmit mode.

I've never opened it, but perhaps there's a means to adjust it inside?
