Re: [Elecraft] MH2 mic and the K3
And a Mea Culpa from me. I have a MH2 that I use very infrequently with my K2 and it works well. When the question was asked, I noted the instructions were different for the K3 but failed to read them carefully. I should have tried my MH2 on my K3 before offering advice. I have only a casual interest in SSB and the MH2 will come in handy for those few special event stations I enjoy working.

Re: [Elecraft] MH2 mic and the K3
I am sorry to disagree, but the MH2 will work fine for both the K2 and K3. They are interchangable. After the repair and configuration of over 1000 K2s, I am quite familiar with the K2 microphone configuration for various microphones. Yes, the K2 mic config header must be jumpered properly and have a bias resistor soldered between pins 1 and 6 on the rear of the mic jack, but once set up it will work. The original poster has his K2 set up to use that microphone already. Moving it to the K3 is simply a matter of setting the MIC SEL menu to FP L Bias. If the MH2 mic fails, the MH4 is a direct replacement. 73, Don W3FPR On 1/26/2021 4:34 PM, Clark Macaulay wrote: Download the MH2 instructions from Elecraft site and you will see that the mic has different jumper settings for the K3.

Re: [Elecraft] MH2 on K3?
Hi Leroy, I recently bought a K3s and after eventually finding out that I had to change the default configuration to have the bias turned on it seemed to work. My MH2 came with an eight pin plug already fitted that uses the front panel mic socket. I still have a problem in that I don't find any difference between the high and low mic settings and need to have my mic gain set at 2 or 3 as well as speak with the microphone about 3 inches away from my mouth otherwise I over modulate which gives a very poor signal. I am sure something is not right but can't find what is causing this at the moment. It may be my big mouth but I don't have this problem with my KX3 which uses the MH3 microphone and "expected" mic settings. Everything just works fine on that. When time permits I will look into fitting a small attenuator into the mic lead so that I can get a more stable ALC reading. I haven't yet tried using the back panel mic socket but may give it a try soon with my Sennheiser headset to see if it overcomes some of the mic gain issues I have with the MH2.

Re: [Elecraft] MH2 vs MH3 mic question
Ed, No they are different. Not only that the MH3 has a 3.5mm TRRS plug and a different mechanism for the MIC buttons(for the KX3) and the MH2 has an 8 pin Foster plug (for the K2, K3 and K3S). The shape of the mic head is different too. The mic element *may* be the same, but I am not certain of that. 73, Don W3FPR On 1/30/2016 11:56 AM, Eddy Avila wrote: Does anyone know if the MH2 is the same mic as the MH3?

Re: [Elecraft] MH2 question
I've never owned or used a K2. However I have assembled two of the K3
kits for others who felt they were not capable of doing so. Thus I have
had the opportunity to use two different K3 radios. One of the very
serious short comings, and main reason for me not purchasing a K3
earlier, is the unsatisfactory quality of the audio. To that end,
with changes announced in the K3S, specifically in the audio section, I
have a new K3S on order. Let's hope it performs or it will be sold.
I've used other radios which do have great audio, both on receive and
transmit. I find it very important that a good mike suited to the
user's voice and good microphone technique is a large part of the key to
great audio on SSB. {key words here {suited to the user's voice} and
{good microphone technique}.

Soon to be a new K3S owner.

Re: [Elecraft] MH2 question
Bob,
Are you saying the K3 TX audio was
unsatisfactory? If so, that's the first report of
it I've heard (assuming everything is adjusted
correctly).
BTW -- re the thread topic: My K2 has always
received outstanding audio reports, though
nowadays I use my K3. But I never much liked the
MH2 mic due to the really strong spring in the PTT
:-) I use a Kenwood M43 with my K3 (and it is
newly synthed).
I'm not familiar with the AB5N mods, though I may
have done something of the sort on K2 #380.

Re: [Elecraft] MH2 question
Ed, Several responses to your post have brought comments regarding the K3 TX audio, but I have not seen any specifically addressing the K2. The K3 TX audio can be tailored using the 8 band TX Equalizer which can be used to make most any microphone sound like the best studio microphone in the world if you are inclined to do a bit of tailoring - no need for an external equalizer, it is built in. If you have a K2, you may be interested in the following - If not, you may want to hit the delete key now, the rest is K2 related. I do not think Gary has aligned many K2s in the past few years. I have handled most of the more recent Elecraft K2 repairs, and do not see your call in my records, so I am wondering just how long ago that alignment was performed. You may want to look at your K2 rather than the microphone. I would hate to see you spend $50 or so on a mod to your microphone and find no added benefit because of limitations in your K2 or your SSBA and SSBC menu settings. K2s that I have aligned often garner unsolicited TX audio reports, and I have received that report from many customers. The MH2 does have the peaking response in the 2800 to 3200 Hz region - the same as many other ham microphones. How old is your K2, and what is the width of the KSB2 filter (2.1kHz or 2.4kHz)? The early KSB2 boards had the 2.1kHz filter while later ones have the 2.4kHz filter - that filter is used on transmit as well as receive. To determine which one you have, look at the capacitor row just to the left of the crystals on the KSB2 board - if all 6 capacitor locations are populated, you have the earlier 2.1 kHz filter, but if there are only 4 capacitors fitted, it is the 2.4 kHz filter. Should you want to change the filter width, Elecraft has the SSBCAPKT available to do that - but check the crystals first. If they are labeled anything other than 49136-S, you must replace the crystals when widening the KSB2 filter. If your KSB2 has the older crystals, your base K2 RF board likely has the older crystals as well and will result in better filters if replaced. Elecraft has a set of 7 matched crystals as well as a matched set of 14 available. The other thing that will affect your SSB transmit (and receive) audio is the placement of the audio passband for LSB and USB. That may be corrected by proper filter alignment (CAL FIL). There is another thing that can affect the K2 TX audio, and that is too much bass. The KSB2 does allow low bass frequencies to be transmitted. While some hams like that, it uses excessive power in the PEP envelope. You can reduce that response by changing 2 capacitors on the KSB2 board. Change C34 to a 0.47uF electrolytic and change C32 to a capacitor between 0.0033 and 0.005 uF. (4700pF is an easily available mid-range value). 73, Don W3FPR On 7/9/2015 11:06 AM, Eddy Avila wrote: Has anyone sent their Heil MH2 to AB5N Bob Nagy for his upgrade?

Re: [Elecraft] MH2 Mic question
The MH2 has an 8-pin connector and I believe the KX3 mic uses a 1/8 tip-sleeve-ring plug. You might be able to make an adapter for it though.

Re: [Elecraft] MH2 Mic and MKII interface
Kenwood mic does not use bias (it is dynamic). Elecraft requires bias. Measure between pins 1 and 7 to confirm bias (2.2 to 3.3V - industry standard for AV mics). Also check to make sure the microphone is wired correctly - mic ground must be on pin 7, PTT ground must be on pin 8. If the two are reversed the mic will not receive bias. Elecraft connects both 7 and 8 to the same ground but the mic and PTT grounds are different in microKEYER/microKEYER II (and most other manufacturers). 73, ...

Re: [Elecraft] MH2 Microphone issue
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. 73, Don W3FPR On 2/25/2011 7:52 AM, KA1YMX wrote: I have a K2 with the SSB option installed and I am having issues getting the MH2 microphone to work.

Re: [Elecraft] MH2 Microphone issue
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. 73, Don W3FPR On 2/25/2011 9:24 AM, KA1YMX wrote: The 5v regulator U5 on the control board has an output of 3.0v.

Re: [Elecraft] MH2 Microphone audio quality
Roy, With the Elecraft MH2, set the Mic Gain to 1 and the compression as you desire, but I like to use 3:1 for normal operation. Watch the bargraph to see an indication of your peak power output - the peaks should be somewhere near the power requested level. I usually find with any microphone on the K2, the compression needs to be advanced to obtain the proper leak power output. Try it with your MH2 and see what the reports are. Better yet, operate into a dully load and couple another receiver with a short wire antenna so you have about an S-9 signal - then record the audio output and evaluate the results. Unless you are well acquainted with the operator on the other end, on-the-air reports of quality can be taken with a grain of salt. Did you purchase this K2 used, and/or do you know what is inside it? What I am asking is if any mods have been made to the KSB2 option, or maybe a mic preamp has been installed. There have been several non-Elecraft mods to the KSB2, and some will work with the MH2 microphone while others could cause distortion. 73, Don W3FPR On 2/25/2011 6:42 PM, Leroy Marion wrote: I just purchased a MH2 to use with K2.

Re: [Elecraft] MH2 Microphone audio quality
G'day Matt, I use my K3 with an MH2 microphone most of the time though for contesting I switch over to a Yamaha CM500 headset. I have found the MH2 to be an excellent mike but you will need to set the TX EQ's 3 lowest bands to their lowest level. Leave all other bands at the 0db point ant you will find that your transmitted audio to be pretty well 'spot on'. Most people I have spoken to with K3's and MH2's use exactly the same settings with great results. (BTW, the same settings also work quite well for the CM500 here too!)

Re: [Elecraft] MH2 Mic arrived DUH!
Neil, The resistance is not critical, so if you have a resistor (of any tolerance) between 4.7k and 6.8k on hand use that. Did you have a tan envelope on the package with the 8 jumpers for the microphone configuration header?

Re: [Elecraft] MH2 Microphone Issue
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! 73 John --- On Wed, 5/26/10, Jeff Cochrane - VK4BOF vk4bof.elecr...@gmail.com wrote: From: Jeff Cochrane - VK4BOF vk4bof.elecr...@gmail.com Subject: [Elecraft] MH2 Microphone Issue To: elecraft@mailman.qth.net Date: Wednesday, May 26, 2010, 7:08 PM G'day everyone!

Re: [Elecraft] MH2 Microphone Issue
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.

Re: [Elecraft] MH2 Microphone Issue
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. 73 Stephen G4SJP On 27/05/2010 03:08, Jeff Cochrane - VK4BOF vk4bof.elecr...@gmail.com wrote: G'day everyone!

Re: [Elecraft] MH2 Mic issue
Steve, Re-check those instructions for the MH2. The resistor goes between pins 1 and 6. Pin 1 is the AF line, and pin 6 is the 5 volt line. You must pipe voltage to the AF line on the mike (through the resistor) to make it produce audio. BTW, pin 2 is the PTT pin. 73, Don W3FPR Stephen Rector wrote: Hi All: I'm new to this list.

Re: [Elecraft] MH2: microphone
They are virtually identical. Same basic mic element, case etc. We took over manufacturing this when Heil discontinued his OEM version suddenly. Apparently he had purchased a group of excess mics and had replaced the dynamic element with the Electret element. (Leaving the unused dynamic element unused inside the case.) When he ran out he suddenly stopped selling them, so we had to locate the manufacturer of the plastic cases and spec our own custom version. For our MH2, the only changes were to eliminate the unused dynamic element left inside the case by Heil, and to improve the foam mounting for the electret element for better mechanical support. Overall the two mics sound identical.

When he ran out he suddenly stopped selling them, so we had to locate the manufacturer of the plastic cases and spec our own custom version. For our MH2, the only changes were to eliminate the unused dynamic element left inside the case by Heil, and to improve the foam mounting for the electret element for better mechanical support. Overall the two mics sound identical. We've bought a very large quantity of these and they will be around for some time. :-) 73, Eric Is the old Elecraft/Heil MD2 plug and play with the K3?

Re: [Elecraft] MH2 vs. MD2
Roger, I can't be certain that they use the same element, but it is likely that they do. They are both electret types. Is it possible that you are holding the MH2 closer than the MD2? Many operators talk very close to a handheld mic but place the desk mic further away. 73, Don W3FPR RCStimson wrote: What is the difference between the Elecraft MH2 Hand mike and the Elecraft MD2 mile in the Stainless Steel case and Heil logo at the bottom?

Re: [Elecraft] MH2 handmicrophones
Ron, The new microphone may or may not have the identical element, but the audio response and electrical behavior will the same.

Re: [Elecraft] MH2 Info/Schematic
Ben, The MH2 that I have makes hot connections only to pins 1 and 2 and ground on pins 7 and 8, so you can use any of pins 3, 4, 5, or 6. If you have wired the resistor to mic jack pins 6 and 1, then pin 6 is not usable unless you modify the 5 volt take-off point on the front panel board. So the short answer is: In a normal K2 wired for the Elecraft MH2, you can freely use mic jack pins 3, 4, and 5 (remember to remove the jumpers for those pins from the mic configuration header so you don't feed anything back into the K2 circuits). 73, Don W3FPR Ben Hofmann K1NT wrote: I have an MH-2 microphone for use with my K2. I can't find the paperwork that originally came with it. I am wanting to use 2 pins on the mic connector for fixed level and variable level receive audio. Was thinking of two of pins 3, 4 or 5, but I wanted to make sure before I did it that hooking the MH-2 to the connector with signals on any of these 3 pins would damage the MH-2 any way.

Re: [Elecraft] MH2 Microphone Discontinued
Hello All, After leaving the Elecraft booth at Dayton with my K2/100/SSB/ATU (SN-004935), DL-1, BL-1 in hand with the understanding that the Heil hand mic was discontinued, I stopped at the Heil booth and asked them what might work. There I was told that a mic with the Icom element and a Kenwood connector will work. Also they confirmed that the MH2 was no longer available. I ended up purchasing a Traveler boomset for Kenwood because I was informed that all of the Travelers have Icom elements and only the connectors are different. I realize that this doesn't directly address the hand mic issue but perhaps it could help with some homebrewing. 73 Mike Warner N3XPD PS, As soon I clear a workable area on my bench, construction of the K2 will begin.

Re: [Elecraft] MH2 Microphone Discontinued
Hi The TenTec handheld microphone works great with the K2. It comes with a 4 pin connector that you will need to change to the 8 pin connector for the K2. This mike works fine with the 5.6K bias resistor from the 5 volt supply to the AF pin, just like the MH2. I have also used the TenTec desk mike on the K2, however it really needs 8-9 volts rather than the 5 volts provided by the K2. You can use the internal 9 volt battery or jumper over to the 8 volt supply in the K2.

Re: [Elecraft] MH2 to MD2 - K2, Modification Required?
Paul, I will find out in a few days, but I do believe the MD2 wiring requirements are the same as for the MH2 - if not, I will make it so. IMHO, if you are using several mics with a particular rig, it is better to wire the plug on the mic rather than re-do the configuration header - my header is wired straight across and will likely stay that way. If the mic must be used with several different transceivers, I believe the best solution is to build an adapter. I would not want to slave a particular microphone to any one transceiver. Maybe we hams should campaign to use XLR connectors on our microphones like the audio folks do (particularly those mics used in the home station - handhelds for field or mobile use are a different situation) 73, Don W3FPR - Original Message - I built a K2 about a year ago and wired it for use with the MH2 hand microphone. As the MD2 is currently on sale, I'm thinking about purchasing one. Can I just unplug the old mic and plug in the new one, or am I going to have to modify the mic input circuitry? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
