    What microphones will work with the HW-101? Which heathkit mic came with the unit?

    If it came with a mic, probably a Turner 350C, Hi-Z device. Any Hi-Z mic will work fine.

    The HW-101 did not have a microphone as part of the kit. The microphone was an optional item. The microphone used quite often, not necessarily the microphone designed specifically for the HW-101, was the
    Electro Voice 638. The HW-101 has an high impedance audio input. Therefore, most, not all, high impedance microphones may work with the HW-101. I use a non-amplified D-104 with my HW-101 and it
    produces excellent audio. While some operators use amplified microphones, I don't recommend them. Amplified microphones, when not adjusted properly, tend to over drive the speech amplifier producing
    distortion in the transmit signal. It's not how loud your signal sounds but rather how clean it sounds on the air. However, it's entirely up to you whether you use an amplified or non-amplified microphone with your

    Thanks to all who replied.

    If any of you have a HW microphone I would be interested in purchasing it.

    James -

    Heathkit did not make "HW microphones",
    rather Heathkit obtained a majority of their microphones (OEM supplier) from Electro-Voice in Buchanan, MI (just down the road).

    For example, the Heathkit model HDP-21A desk microphone was an option for the 1960s/1970s HW and SB transceivers.
    That microphone is actually the Electro-Voice 638 with a brushed finish on a nice matching desk stand.

    Electro-Voice was about 15 miles from the Heath plant on Hilltop Road in St. Joseph, Michigan. Mailing address was Benton Harbor but the actual plant location was on the south-side of Benton Harbor in St. Joseph.

    I used both a D104 (un-amplified) and a Turner 222.

    I also used a turner hand mic for mobile.

    I use a vintage Astatic DN-HZ (Hi impedance) un-amplified dynamic mic. I got it from a ham who used it as a full frequency response mic for AM operation. I love it & my HW-101. The HW-101 has a "punch" which the modern rigs just don't have. Tubes rule! The attached photo shows the DN-HZ behind my cat as she copies CW! 73, Ken

    I see that the cat was working the "rubber" band. :)

    Yep, the "Heathkit" mobile mic sold in that era was the Turner 350C. Used one with my SB-102 with great results. The Cheyenne, at first, came with the Electro-Voice 729SR (little help, 729 or 727?). I used one of those (without the switch) with a HB modulator. loved the shape of that mic.

    Later, the Cheyenne came with the Turner.

    Took a while, but finally found a 350C at a hamfest last fall. Will be the mic for the Cheyenne I also got last Spring, and probably my TR-3 and, ta-da!, my G-76. ceramic mics last indefinitely? Think Heath claimed they did.

    I have to look and see just which microphone model the original one shipped with the MT-1 actually was.

    Ceramic microphone cartridges usually do last for decades. Unfortunately, crystal cartridges do not.

    Just yesterday I saw the light-colored 350C with the Heathkit emblem on eBay. Price wasn't bad. It'd be the perfect match for a Cheyenne. There were two colors, light and dark green.
    Thanks for the info about ceramic mics, Glen, guess I'll find that mine's just fine. Even came with the original box.
