Heil Handi Mic
Locked
 
|
Greetings, all
I recently acquired a Heil Handi-Mic with the HC-5 element, intending to use it with a new K2 radio (#5510). I used straight-across wiring for the configuration connector in the front panel since the Handi-Mic is equipped with a cable wired for Kenwood mikes. No resistor from pin 1 to pin 6 since the element is dynamic. The mike does work, but the output seems low -- the ALC indication barely lights the top bar, and the RF output barely shows on the louder peaks. A MH-2 mike shows a little more output, though not that much more. The over-all feeling is that the Handi-Mic has a relatively low output level and may need a preamp to work properly with the K2. The mike works about the same with either K2 here. I've noted the diagram for a mike preamp for the K2, but before I build up something like that, I'm just wondering if anybody else has tried the Handi-Mic, and what any experience has been with respect to driving the K2 with that mike. Comments, anyone? ? ? TIA, Van W1WCG K2 #2634, 5510 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Van,
The Heil HC-5 and HC-4 mic elements do produce less output than many other types of mic element, and you will find a number of Posts to the List discussing this issue. Unless these mic elements are quite close to one's mouth it does seem that a preamp is required with the K2. I use a Heil Proset Plus headset which has a boom assembly containing a HC-5 and a HC-4 which means that the mic is about 2 or 3 inches from my mouth, and I do not need a preamp to drive my K2/100 to full specified output, in fact on 40m I have to move the mic a little to avoid the ALC becoming too active. FWIW my wife says that I have a 'quiet' voice. 73, Geoff GM4ESD Frank Van Cleef W1WCG <[hidden email]> wrote: Greetings, all I recently acquired a Heil Handi-Mic with the HC-5 element, intending to use it with a new K2 radio (#5510).

I don't have personal experience with the Heil mic, but you are describing a
K2 making full power output if I understand your comments correctly. When the first (right hand) ALC bar just flickers, that means the mic is providing *more* audio than the K2 needs for full RF output and the ALC is turning down the overall transmit gain. So, if you have the POWER set for a K2 to produce 10 watts or a K2/100 to produce 100 watts, and one ALC bar flickers, more audio from the mic will do no good at all. It's important to check that at full RF power. As you turn down the power you'll see more and more ALC bars light as the level control reduces the output to match the POWER control setting. (The K2 should not be run above 10 watts on SSB to avoid unnecessary distortion, although running the power "wide open" on CW is FB). You also need to have whatever maximum level of compression you want to use switched On and do the test on the band where the K2 has the *least* transmit gain. That's always been 10 meters on all the K2's I've heard about and seen. If you get an ALC bar flickering under those conditions, more mic gain does nothing for you. If not, then perhaps a preamp will help. Watching your RF output, the bar associated with the maximum power should just lightly flicker unless you are using a lot of compression. Human voice has a huge average-to-peak amplitude ratio, and the peaks are very brief and infrequent compared to the rest of the spectrum. The RF bargraph display is a "peak reading" display so it fairly accurately indicates the very brief and infrequent voice peaks. One very simple change in the K2 that makes a large difference for mics with marginal output is to change resistor R14 on the SSB module board from the original value of 1k ohms to something between 5.6k and 10k. That resistor is across the mic input. Increasing its value raises the audio level presented to the speech compressor.

Frank,
Unfortunately the Heil HC-4 and HC-5 elements have lower output than typical mics. There is one in the Handi-Mic set that should work well with the K2 - and that is the one for the Icom (Heil number HM-iC) perhaps you could arrange an exchange. In general the Icom mics use an electret element with high output level - the audio input needs of the K2 and the Icom are similar. If you do wish to retain the HC-5 element, then your best choice is to use a pre-amp. There are work-arounds such as changing the value of KSB2 R14, but IMHO, the best all-around solution is to use a pre-amp and set the pre-amp gain to provide the output needed by the K2. If I recall correctly, the proper output level is -40 dBm. 73, Don W3FPR > -----Original Message----- > > I recently acquired a Heil Handi-Mic with the HC-5 element, > intending to use > it with a new K2 radio (#5510).

I am using the Heil HM-5, and the audio is just fine according to reports.
I didn't have to do anything special. I set SSb A menu to 2, and SSbB menu to 3-1, And it works well for my voice. Just another option.

I considered an external preamp, but it seemed to me more efficient to reduce the unnecessary loss at the mic input rather than add external active components to make up for it.

While at Pacificon this fall I purchased a Heil Handi-Mic for my K2 #0261.
I've read this list for a long time now and know about the K2's need for a mic with higher-than-normal output. Researching the Handi-Mic on-line I expected the model HM-iC (for Icom) would be the right choice. So before making the purchase I went to the Elecraft booth and asked THE MAN, Eric Schwartz, and he said that's the one to get. Well, I haven't found out for sure yet because I still need to build my KSB2 but I have no doubt that I got the right info from the right man. Don's response (below) seems to agree. I also purchased the Heil CH-1K (Kenwood) cable to go with it, the plug matches the K2 and Eric said I can then use the default setting on the KSB2 header. It should be a nice setup. 73, Gene K6TTM > -----Original Message----- > From: [hidden email] > [mailto:[hidden email]] On Behalf Of Don Wilhelm > Sent: Monday, December 04, 2006 10:57 AM > To: Frank Van Cleef W1WCG; [hidden email] > Subject: RE: [Elecraft] Heil Handi Mic > > > Frank, > > Unfortunately the Heil HC-4 and HC-5 elements have lower > output than typical > mics.

Sounds like that will work perfectly. :-) Make sure you add the
microphone bias resistor to the K2 for this mic. 73, Eric Swartz WA6HHQ http://www.elecraft.com Gene Langendorff wrote: > While at Pacificon this fall I purchased a Heil Handi-Mic for my K2 #0261. > I've read this list for a long time now and know about the K2's need for a > mic with higher-than-normal output.

Hello All,
There seems to be differing opinions about whether the Heil HM-4 and HM-5 provide enough output to properly drive the K2. Looking through the HRO catalog, I found that Heil now has several electret mikes (HM-iC, iCM, etc.) which they say gives higher output, but they also say these work only for ICOM radios... Does anyone have experience with these mikes? Do they solve the low drive problem for the K2?... And why are they "only for ICOM radios"? And one final question: are they likely to work better than the mike that I'm using that I put together using a $3 Radio Shack electret replacement element (plenty of drive, but mediocre audio reports)? Thanks.

Bob,
Unlike other radios (Icom, Kenwood, Yaesu, etc) that have their own method of wiring the mic jack and make it inconenient to impossible for the user to change it, the K2 has a microphone configuration header so you can rearrange the mic jack wiring to suit any 8 pin microphone configuration. The information for the wiring required is in the KSB2 manual. Yes, an Icom mic can be used on the K2 - connect the microphone configuration header for the Icom wiring and in the case of the the electret type mic elements, add a resistor from the AF mic pin to +5 volts. Most mics suggest a 10k resistor, but usually the other end of the resistor is connected to an 8 volt supply - the K2 supplies only 5 volts and a 5.6k resistor is more appropriate. In the case of Icom wiring, the resistor connects between pins 1 and 2 and the mic header has a jumper from the 5V pin to pin 2. 73, Don W3FPR > -----Original Message----- > > There seems to be differing opinions about whether the Heil HM-4 > and HM-5 provide enough output to properly drive the K2.

Hi Bob,
The Heil iC elements work perfectly with the K2. They use the same element that we used in the MH2. (As a side note: The Heil HC4 and HC5 elements put out about 8 dB less than the industry standard used by almost all other ham radio manufacturers, hence the low gain reports in some instances.) If you want to use the standard Elecraft 8 pin mic connector set up, which allows you to jumper straight across on our mic configuration header, you will want to request the Kenwood style cable from them. I'll give Heil a call and request that they re-title the ic microphones as compatible with Elecraft too :-) 73, Eric WA6HHQ ----------- Solosko, Robert B (Bob) wrote: > I found that Heil now has several electret mikes > (HM-iC, iCM, etc.) which they say gives higher output, but they also say > these work only for ICOM radios...

Bob, and the List:
I bought, and still use, a Heil MH2 electret mic when it was offered for sale through Elecraft; then it was called the Heil MH2. That was several years ago as I recall. The MH2 works FB with plenty of output and good-quality audio according the reports I get on the air. I'm mostly a CW user, but the little handheld MH2 seems fine for my needs, and the K2 seems happy with its output level. My relevant K2 MENU entries are : SSbA 1, and SSbC 1-1. The MH2 is physically connected to my Rigblaster interface, which then connects to the K2 8-pin Mic connector. The only reason I can see that Heil would say the HM-4 and HM-5 are only for Icom rigs might be that their mic connector pins might be wired differently than the K2 expects to see. Certainly you ought to be able to play with your RS electret replacement element without hazard to your K2. Keep us posted, es GL. 73 K0PQ Steve Banks -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Solosko, Robert B (Bob) Sent: Wednesday, December 20, 2006 7:19 AM To: Ron D'Eau Claire; [hidden email] Subject: RE: [Elecraft] Heil Handi Mic Hello All, There seems to be differing opinions about whether the Heil HM-4 and HM-5 provide enough output to properly drive the K2.

Hi Eric --
Since I have a Heil ProSet with the HC5 element, and I get outstanding reports with it on Kenwood and Yaesu rigs -- my question is, if I connect it to a K2, will the 8 dB difference in output level cause any problems, or is there enough residual mic gain in the K2 to make up for it?
