I sure like my MH2 (athough it rarely gets any action). I guess it's value
just went up ;) ....not for sale! I can't imagine how it could be improved.

Probably nothing other than low sales volume.
I think most hams equate hand mike = cheap mike. OK for mobile work, but not in the shack. So a premium hand mike is probably not going to be a big seller for any vendor. I have a drawer full of hand mikes from all the rigs I've bought over the years that advertised "Mic Included!". I wonder if a guy could just buy the Heil-Icom element and stuff it in one of the thousand Kenwood hand mikes available at every swap meet? Anybody had any experience with that?

For HF I don't use a hand mic anymore. Instead I use the Heil BM-5 headset. Solves a few problems. I don't like to use an external speaker for HF mobile as there is so much road noise and band noise it is difficult to copy weak signals. The headset is definitely the way to go to improve the "local signal to noise" ratio. Also reduces noise for passengers who may not have an interest in listening to the HF noise either. This situation is completely different than a VHF/UHF rig used on FM which doesn't have the same "local s/n" issues. Only problem I still have is that I need a PTT switch or use VOX. I don't like to use VOX because if I have passengers in the vehicle or accidentally use an explative due to some other bad driver nearby I don't want to transmit. For PTT I put a momentary pushbutton in a pill bottle. Would be cool to mount it to the gear shifter directly, but I just hold onto the pill bottle.
Also found headsets a great asset for contesting as well. I doubt I'll ever use hand mics again on HF!

I've got both - an old Cobra (label removed) CB 600 ohm dynamic and a boom headset salvaged from a cell phone (2.2k). ---------------- A typical electret does very well on a K2. Electrets are not necessarily a high-impedance element. The impedance the rig "sees" will be the value of the dropping resistor used to supply d-c bias to the mic element "hot" side. Since the d-c voltage source for the bias is grounded for audio (has large capacitors to ground in the circuit), the resistor becomes the audio load between the audio line and ground. My electret uses a 1k resistor, so its impedance is 1k ohms. It is true that a high-impedance mic won't normally sound good on a rig expecting a fairly low impedance mic, like the K2. Connecting a typical high-impedance mic to a low impedance will normally cause the lows to be lost, making the mic sound very "bright" or "tinny". Very few such mics are still around. Even the venerable "D-104" was updated with an amplifier in the base to convert the very high (appx 0.5 megohm) impedance of its crystal element to the lower impedance most current Ham rigs want. My mic is 'homebrew' - using an inexpensive (< $5 USD) electret element mounted in a hand mic enclosure that originally contained a cheap dynamic element. The electret element has a frequency response far, far greater than the K2 needs: from about 30 Hz to about 16 kHz. The transmitted bandwidth is controlled entirely by the K2's SSB module filter. People tell me it sounds excellent on the air. Ron AC7AC _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I go with RON on this one.
After 30 years working ( under contract) with companies that include Sennheiser, AKG and Shure Brothers, all who actually manufacture microphone elements. They taught me some things. I have bought a few Sennheiser boom headsets on Ebay... great headphones ,, and i have some mics for my K2 icoms and tentecs made from electret elements scrapped from telephones...nortel, panasonic. ALL electrets are WAY TOO GOOD for communications audio.... even the one you get at radio shack for $ .99 US. Just stuff it in a gooseneck and you have a GREAT base station mic.... don't forget the ptt switch... another $ 1.29..... It's Sooo cheap you owe it a try. bill >---------------- > >A typical electret does very well on a K2. Electrets are not necessarily a >high-impedance element.

Great point, sorry I forgot the normal <lawyer speak> disclaimer.
Please note that the headset I mentioned is only a single hearpiece headset specifically chosen for that reason. For all future correspondence from myself and others it is suggested that common sense and failing that adherence to the applicable laws which are put into place for those who don't have enough of the former. ;^) Mark, NK8Q Wayne Reed wrote: > I hope we all remember that it is illegal to drive with headsets of > any kind covering BOTH ears, or did I dream that? > Wayne, K9NE > > ----- Original Message ----- From: <[hidden email]> > To: "EricJ" <[hidden email]>; "'pa3gyu'" <[hidden email]>; > <[hidden email]> > Sent: Friday, May 27, 2005 10:52 AM > Subject: Re: RE: [Elecraft] Heil handmike discontinued. > > >> For HF I don't use a hand mic anymore.
