My 30 year old heil element finally bit
the dust. I bought an Elecraft MH4 hand-held mic and am trying to get it adjusted. I checked in with a local net and was told there is a kind of clipping on my words, like the ends of some word were being cut off. Another report said it sounded more like there was an artificial sound in-between the syllables, that it wasn't on the peaks but noted in the the troughs, perhaps a bit of clicking in there. I don't hear any difficulties with the monitor, everything sounds like normal words with no distortion. I'm not using VOX and have no idea what I might try looking at to resolve this. As to the equalizing of the MH4, is there a set of values with the 8 bands to give it more of a character of a Heil HC4 element or something well suited for DX? Any suggestions on the clipping & Mic TX EQ & what I might try doing to resolve this? 73, Gary KA1J ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
I would look closely at the ALC level and the CMP level to see that the
new mike, which has more output, is not driving things into saturation. Likewise, as Jim, K9YC says, use the TX EQ to get rid of some of the low end, thus not to suck up power which is not heard on the other end. And check to see that the mike is not over driving the input stage. If your MIC gain is less than about 20 and the menu is set for higher gain, then set the gain to a lower value per the menu and adjust the MIC gain for a higher value to attain correct ALC action of 5 to 7 bars. See page 22 and 30 in the manual. These radios really sound GREAT when all is adjusted correctly. 73 Bob, K4TAX On 10/10/2018 1:10 AM, Gary Smith wrote: > My 30 year old heil element finally bit > the dust.

Gary,
If you just plugged in the MH4 and turned on bias, then I suggest that may be the cause of the problem. Assuming you had the K3 set for the low output Heil microphone, you should change the MIC SEL menu to FP.L bias. If you have MIC SEL still set for FP.H, you may be overdriving the mic preamp. The MH2 has a high output level, so you need only low gain in the K3. Then initially set the compression to 0 and set the MIC GAIN to produce 5 to 7 bars on the ALC meter while speaking into the microphone in a normal voice. Once that is done, set the compression to a moderate level of your choice. As Bob K4TAX has pointed out and K9YC has long advocated, set the lower 2 bands of TX EQ to the lowest levels and set the 3rd band down a bit as well - that will increase your "talk power" while not wasting power trying to transmit those low frequencies which are not needed for intelligibility. If you are into ESSB, you may differ, but ham radio is not HI-FI in my opinion, it is about communications effectiveness. 73, Don W3FPR On 10/10/2018 2:10 AM, Gary Smith wrote: > My 30 year old heil element finally bit > the dust.

And if all of this fails look for a blown HPA.

For my SM58 and my K3S I use the following:
50 Hz -16 100 Hz -16 200 Hz - 9 400 Hz 0 800 Hz 0 1600 Hz 0 2400 Hz +3 3200Hz +6 The Behringer XM8500 dynamic mike gives identical performance and it costs only $20. Heard one and just had to try it. I can swap between the SM58 and the XM8500 and folks that I rag chew with on a regular basis can't tell the difference. Even the machining pattern on the base is the same on both mikes.

The SM58 is representative of a wide variety of the hand-held "vocal" mics by many manufacturers. It would not surprise me if they didn't use a common element - probably manufactured off shore - which means the read difference would be in mounting and the wind screen which would effect handling/wind noise and not particularly impact the response. > For my SM58 and my K3S I use the following: > > 50 Hz -16 > 100 Hz -16 > 200 Hz - 9 > 400 Hz 0 > 800 Hz 0 > 1600 Hz 0 > 2400 Hz +3 > 3200Hz +6 For my voice, I like to set 800 Hz at -10 dB (not much energy in that band so I reduce the room noise) and then +3/+5/+6 at 1600/2400/3200 (a smooth 3 dB/octave preemphasis). For "DX", the +3/+5/+6 can be pushed to +5/+9/+10 (5 dB/octave) to emulate the HC4. 73, ...

Shure manufactures ( or at least did when I repped them) in Mexico at
their plant. They also were maintaining capabilities of manufacturing in the states,,, used to be Evanston.. now has plant in Wheeling, IL. Those old 444 and 450 paging mics were always emphasizing the 2.5 - 3 k region..

First, I don't think any Heil mic ought to be taken as a standard. I
view Heil as most audio professionals view Bose -- "better sound through advertising." Second, the SM58 is a single-D cardioid, and Shure's published data is for the mic at considerable distance from the sound source. When used close to a sound source, there is a LOT of bass boost as a result of proximity effect, so the "close-talked" response requires a lot more low-cut EQ. Third, My standard recommended starting point for TXEQ for ALL mics is max cut of the three lowest bands, 6dB cut of the 4th (400 Hz) band. Some mics, including the Shure 444 and some Heil mics have an intentional boost around 3 kHz to compensate for the rolloff of SSB transmitting filters, and I view this as a GOOD thing. For mics that lack this boost, or have have the boost at a much higher frequency (the SM58 has a boost around 8 kHz), I recommend a boost of 3-6 dB in the top two bands. All other bands should be set "flat" (no boost, no cut). After making these settings, adjust COMP to see about an indicated 10 dB of gain reduction on voice peaks, then get signal reports from a good listener. These settings are for maximum talk power, NOT for high futility, and if done right, will multiply your effective power by about 20 (13 dB). That will make you easier to copy on the other end, which, for me, also makes casual QSOs and ragchews easier on the ears when you're not booming in on the other end. 73, Jim K9YC On 10/10/2018 11:07 AM, Joe Subich, W4TV wrote: > > If one has a flat "wide band" mic (electret) the typical TX EQ settings > needed to emulate the Heil HC4 (DX)/HC5 elements, a couple classic > "communications" mics and a typical dynamic "vocal" mic (SM58) are: > > -- SHURE -- > HC4 HC5 D-104 444 SM58 > 50 -16 -16 -16 -16 -8 > 100 -16 -16 -10 -16 -2 > 200 -16 -3 -4 -7 0 > 400 -4 -2 -3 -2 -1 > 800 -0 -2 -1 0 -1 > 1600 +5 +2 +3 +3 +0 > 2400 +10 +5 +9 +7 +1 > 3200 +10 +6 +13 +12 +4 > > Thanks to: <https://owenduffy.net/audio/legend/index.htm> for the > HC4/HC5/D-104/444 response curves.

This is generally true of REAL microphone companies, like ElectroVoice, Sennheiser, AKG, Neumann, and Beyer. Last I heard, EV's plant was in TN. Sennheiser, AKG, Neumann, and Beyer are German companies, and I suspect their mics are still manufactured there.

As a long time member of the AES Standards Committee Working Group on Microphones, I know engineers from most REAL mic mfrs, and I've heard horror stories of counterfeiting of their products, mostly from China. They often LOOK absolutely identical, but they are NOT the same and don't perform the same. The same is true of connectors -- the common problems with the counterfeit parts are that they don't mate solidly, dielectrics may melt when you try to solder them, they may fall apart, they have dissimilar metals issues. Companies like Heil and Behringer ARE buying cheap generic capsules and putting them in fancy housings. Big companies like Yamaha, Panasonic, and Sony probably DO mfr their own mic capsules and headphones. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

In reply to this post by Jim Brown-10
Folks,
Thank you for all the replies regarding the clipping and a thank you for the replies regarding proper setting for the Mic. That's just what I was looking for. Unfortunately my transmit issues remain. I'm beginning to think there is perhaps something wrong with the radio. I was on 40M today, checking out the results on my grounding efforts to see if that made a difference. Many came on to tell me I indeed still have a problem. One person said the audio effect gave them "goosebumps" so there's something definite going on. One common thread was my signal seems to be cutting in & out. Although I don't hear it in the headphones, it must be rendered in a later stage. A few said it sounded like RFI. I'm stumped... However, when following Don's suggestions on adjusting the ALC level and then compression I noticed something unusual & I think, not right. When I have the headset on, monitor on a high volume setting & I key the mic, I hear a very clear and loud low reproduction of the ambient noise in the room, almost like a low frequency hearing aid. The moment I adjust either the mic or compression, that character completely stops and the background sound in the headphones becomes silent. It is exactly to me, like hearing a rumbling background noise with Bose QC-15 headsets and then flipping the power on and hearing the background drop out to be replaced with ambient silence. I've tried this multiple times and it is always the same, it's as if turning compression or MIC engages some noise cancelling from the K3s. My voice changes from somewhat bassy albeit clear, effect like talking close into a condenser mic, to the brighter, non bassy settings I have adjusted the TX EQ to be. Does this sound familiar? If so, what might I look at?

If you are using the MH4 Elecraft mic plugged into the front panel. Set mic to “FpL -bias”. Set EQ to flat. Set Cmp to zero and adjust micgain for 4-5 bars ALC. Now adjust Cmp to provide about 10dB and get on the air and get assistance from someone who knows your voice.
If you’re having intermittent issues check ALL connections. If you have Monitor on keep it low or it will get into the mic and give you grief. Better, use another radio receiver to listen to yourself transmitting into a dummy load. Even on of the many SDR Dongle type will work great.

transmitting into a dummy on another radio was a good idea. However, I pulled my backup K3 out of its box & replaced the K3s with it. It's Serial #202 but it is updated to the final K3 specs and has most of the K3s upgrades so I just switched one for the other. I matched the config from the K3s to the K3 so they are set up the same. Zero issues with the K3, all reports say the audio is excellent with no hint of RFI. Seems like I have a problem with the K3s. Unfortunate in that it was just returned from repair this last August but things happen. Thank you all for the replies, great ideas and I set the TX EQ to the settings Joe, W4TV, provided for this mic. The audio reports have been excellent so that helped greatly. I'll get a RMA and send it out tomorrow. Thanks & 73, Gary KA1J > If you are using the MH4 Elecraft mic plugged into the front panel. > Set mic to "FpL -bias". Set EQ to flat.
