The standard mic element in my HR2510 bit the dust so decided to replace it with the Heil HC5 element and decided to also replace the one in the standard Ranger 2950dx mic as well.
The first thing I noticed was that with the mic about 10 inches away modulation level was down but moving it up to three inches away from my mouth the output was the same as before. Everyone has given me good reports on the quality of the signal and this was an easy modification to do.
At some stage later I would like to do the same modification on a power mic like a D104 to see if there is any improvement |

Bob Heil recommends close talking his elements at about 2" from your lips to get maximum intelligibility. Sound energy deteriorates quickly so the closer you are when speaking into the element the better your voice will sound. |

Hi Murray,
I bought HC104 the proper Heil D104 conversion Kit. It consists of a HC5,rubber ring surround and foam mounting. The reports are OK but nothing really that different to the original crystal element on SSB. However like youve reported you have to be 2 inches form the element as the audio quality will be lacking bass.As Hollowpoint 445 says Bob Heil recommends this 2" rule to all of his mic elements. Kind of defeats the concept of having a base mic at arms lenght!!
Ive had better reports using the Astatic SSB Head, ie the 10 DAL. This works a treat on SSB and you dont have to be so close to get good audio.
Let me know how you get on.

Oh yeah one other thing. If you really want to make your HR2510 really sing I suggest you try to get hold of a Turner Super Side Kick. This is better than any of the Astatics in my opinion. |

Actually it reinforces how a microphone is supposed to be used. Having the microphone at arm's length increases background noise and decreases the detail of your voice. If a desk microphone is uncomfortable for you to use that way they make adjustable booms to get the microphone right up to your mouth. |

Tim and Hollowpoint, thanks for the comments, it sure is worth trying different mics. I am now using an amplified tug8 for base use on the HR2510 and this seems to put more audio up the stick and I have also just become the proud owner of an Astatic Silver Eagle which I will rewire for the Ranger 2950dx, hopefully this will have the sme effect.

Hollowpoint 445. I hear what your saying and it does make sense but when have you ever heard a Turner Super Side kick or Siver Eagle needing "detail". These mics can hear a pin drop?! Sure these mics might amplify a little back ground noise but when has that ever been a problem when your working DX on the other side of the world getting 5/9 reports and compliments on your audio?? These mics are tried and tested over time. Sure the Heils have a more mellow sound but do we really need it on CB? After all we are communicating not broad casting !! |

True, but ask yourself why broadcasters close talk microphones. Broadcast studios are pretty quiet so if distance is not a big deal they could sit back in their chairs and just turn up the gain. But they close talk microphones. Why? Because it sounds better.
My goal is to sound like I'm chatting with someone across a table rather than across the country. I don't want to sound like I'm screaming, and I don't want my voice to be harshly equalized by a microphone that has much better response to higher tones.
I listen to my signal off the air with headphones on another radio, and often tape it as well. Through this exercise I know that close talking the microphone sounds better and that's why I do it. Try it yourself. I think you'll be surprised by the qualitive difference it makes. |

Hollowpoint I agree. Theres a fellow near me who uses a D104 at arms lenght. I'm sure his gain is set full. You can hear him breathig and even a clock in the background. I don't know why people think this sounds good. I also believe that when you close talk your voice will travel farther. The radio transmitting the furnace or tv background is a waste of power. All you want is your voice. I have tested this at a distace of 30 miles. I could not make out what the person was saying with D104 gain set at full and arms length. When he turned it down and talked 3 inches away he blasted in like he was next to me. Its a shame when someone whos been into radio more years than I've been alive cannot figure this out. Another one is the guys who for some reason seem to think they need to yell into the mic. The farther out the louder they yell. Not knowing they are harder to understand by the reciever. lol
I have tried some of your technigues Hollowpoint and my audio has greatly improved from it, thanks. cef 491 Hotwire |

Glad to help. Radio is more fun when you've got good audio. More people will chat with you, and they'll ask your advice because you sound better than other stations. Now if I only I can convince everyone that louder isn't always better..... |

Yeah, loud is ok but I prefer a comfortable level. I think the majority is more concerned about being the biggest and baddest. I just like to make QSO's and FORGET ABOUT IT!!! |
