Re: [Elecraft] Heil Handi Mic
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?

RE: [Elecraft] Heil Handi Mic
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.

RE: [Elecraft] Heil Handi Mic
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.

RE: [Elecraft] Heil Handi Mic
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.

Re: [Elecraft] Heil Handi Mic
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 <[EMAIL PROTECTED]> 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).

RE: [Elecraft] Heil Handi Mic Configuration Question
Jonathan, At best we can but guess that your mic (or the K2 mic configuration header) is not connected as you expect - did you add the resistor on the back of the mic jack or the mic configuration header to support the use of the Electret element (since this is an ICOM type mic based on the -IC suffix, I assume the element is the electret type, but again I could be wrong on that). Bottom line - trust no one until you can substantiate that what you have in your hands is connected as expected. It may take the steps of disassembling the mic and checking continuity from the element and PTT switch to the pins on the mic plug to really know the truth of that matter. Until that is known, everything is a 'guessing game'. Heil has a wide variety of mic configurations and some very different wirings appear under the same mic type number, so you have to know what you have in order to connect it properly. Once we know the element type (dynamic or electret) and know which signals appear at what pins on the mic plug, we can tell you how to configure your mic configuration header. One other thing - the carrier that you experience may be the result of failure to properly set the carrier balance pot on the KSB2 board. Have you done all the KSB2 alignment yet? 73, Don W3FPR > -Original Message- > > I am finishing up K2 #5113 and have run into a snag configuring the > microphone on the K2SB2.
