BM800 Microphone and Icom SM-50 Comparison – Recorded Audio


I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

    I just connected a Heil ICM mic, and was surprised to learn that I now must set mic gain to 10% with comp on, or
    18% with comp off. Your BM 800 sounds good.

    Hi Rich
    For some reason my laptop cannot play your files.
    Either unsupported format or wrong path.

  3. K0PIR says:

    Yeah my iPad Pro is having a problem. Are you on a Mac?
    I updated it and you should be good now.
    Thank you for the input.

    Best 73,

    BM800 gets my vote, but both sound good to me.

    Hi Rich,
    For me the BM800 Microphone sounds much better than the SM-50.
    However, I am 73 years old and I know that this might not be true under hard conditions.

  6. K0PIR says:

    Thanks Ken. They are both good and a friend who views it on a scope says the BM800 is better.

    Hi Rich,

    Have you tried either microphone with your Drake TR-7?

    Hi Rich,
    From my OLD ears, there is not a lot of difference from the BM-800 and the Icom SM-50 set to the “Low” position. However, I prefer the audio from the BM-800, it may have a little wider audio response and a little more presence.
    Thanks, Ed KD5EH

      Hi Ed,
      Nice to hear from you and thanks for commenting.
      I’m leaning towards the SM-50 in the LOW position only because it was 5X the price of the BM-800 Hi Hi!
      See you on the BC!

    Hi Rich,
    I favor the sound of the BM800.

      Hi John,
      Nice to hear from you and yes I am convinced now. I think the BM800 just edges out the SM-50. I guess the SM-50 is going to the camper, hi hi.

    Hi Rich,

    I have the 7300. Call me a ninny, but can you show how you connect the BM800 to the 8 Pin Mic Headset Adapter HS 01 C? The 8 pin has 2 connections and the BM800 (as far as I can see) has one.

    I just want to make sure I am getting the right parts for the project.

    I’m not to savvy with the microphones.

      Hi Eric,

      Nice to hear from you and thank you for commenting here.

      You plug the BM800 into the mic end of the HS 01 C (Y cable). The other connector on the Y cable is for a foot switch. You can use the BM800 without a foot switch by using VOX.

      I use a foot switch like this one. My Y cable takes a 1/8″ plug on the foot switch.

      I hope this helps.

  11. Eric says:

    HI Rich,

    Do you think there is any difference in these two mics, although they are the same?

    Between the Zingyou and Voilamart, that is.

    Thanks for any help.


  12. K0PIR says:

    Hi Eric,

    Same mic as the BM800, just different names.

    Rich, K0PIR

  13. Sean Dickerson says:

    Just got all of my parts for this exact same setup. We’ll have to catch up soon! Thanks Rich!

  14. Eric says:

    Hi Rich,

    I just got the HS-01CD adapter along with the BM-800, but the Mic isn’t working.
    The PTT works fine.

    I received a HS-01CD. Do you think that the HS-01CD is different from the HS-01C?

    When I clicked on your link, the CD was the suggested.

    The seller is out of town for a couple weeks, so my inquiry will be delayed.

    Any suggestions are greatly appreciated.



  15. K0PIR says:

    Hi Eric,

    Thanks for commenting here and sorry to hear about your trouble. I clicked on the link and it took me to the expired listing (the one I have) that is for the one ending in C. I read the description of the CD and it is for a dynamic mic. You will have to send that one back and get the C. The BM800 is an electret condenser mic and needs power.

    I will look for a better link. Thank you.

    Rich, K0PIR

  16. Eric says:

    Hi Rich,

    I was afraid of that. For some reason I thought dynamic was the one that would have worked.

    I did email the seller, but he is out of town right now, so I will let you know in about three weeks.

    If I dared to, can’t I just rewire the one I have?

    I guess I don’t understand the difference between the two.

    I searched eBay and came up with no matches.

    Thank you for all your help.

    As I said, I will keep in the loop.


    • K0PIR says:

      There is a capacitor in the line blocking the mic bias. I would wait for the seller to return and ask him about it. Tell him what you have and what you want to hook up.

      I’ve had many times where I had to wait on the right part to come in. Just part of the hobby, hi hi. You’ll enjoy the BM800 when it’s done.

      Rich, K0PIR
