Projects Unlimited adopted a 'Smart Part Numbering System' that includes the device's parameters. They have extensive listing of microphone elements. I would rather produce the top lift electronically.Д¬lick to expand.PUI Audio is a family owned business founded in 1972 with its HQ in Dayton, OH. Icom mics mount the capsule in a small cavity with a tiny hole at the front to give HF boost but the drawback of this tiny hole is that it makes the mic sensitive to plosives. I put sound damping within the ones I modify and make sure that the front of the capsule is sealed against the front of the housing. Problem solved.ДЄs Roger says, be careful not to form a cavity within the mic housing. Now I put a decoupling cap right on the mic terminals and feed through a small RF choke. Turned out that the RF was getting into the mic capsule, picked up on the mic lead. I had one that I could not get rid of the RF pickup despite much filtering at the radio end. One thing I haven't seen mentioned in relation to the electret inserts is that they can be prone to RF pickup. They can also overload with high sound intensity as the FET bias is usually far from ideal. Signal to noise ratio is also variable between types and for studio use, would not be good enough in most cases. The capsules response does vary quite a bit between different types but not noticeably over the tiny range that we can use. That was chosen for its good cardioid response.

even doing it on a Beofang handheld drastically improves the audio !Д¬lick to expand.Yes, me too, even though I do use a Rode dynamic mic. In fact, with most rigs that come with an Electret capsule mic, simply enlarging the hole in front of it will drastically improve the audio - I have done this on my 2M FM rig mics. You also often have to open up slots or holes in the front grill of handheld PTT Mics, as they are usually much too small, which results in a lack of bass. So I have always done the same ever since on different rigs, and regularly get excellent audio reports, with people asking if I'm using an external mixer & Studio Mic !Д«ut as I say, you have to play around to get the mounting right, as it can alter the frequency response. and it sounded SO much better than using a tailored Mic !

Once I had it sounding good, I tried it on the rig, and it sounded superb on AM.Д«ut then I tried it on SSB. (I adjusted it by feeding it into my mixing desk and recording it, not on the rig) I spent a lot of time playing around with the mounting, as even small changes drastically changed the frequency response. So I took out the tailored Dynamic Mic Capsule and put in an electret capsule. yet they have all the excellent transient response that you get from a proper high-voltage Condenser Mic.ДЈ0 years ago I used to go on a local 160m AM net, using my FT101E, which produces really good AM. These cheap Electret Capsules are more than adequate to give a flat frequency response across the limited 3kHz bandwidth. but I wouldn't dream of using one of my Studio Mics on any of my rigs. It makes me laugh all these people using expensive Studio Condenser Microphones on an SSB rig ! I'm a Broadcaster and former Sound Engineer, and have my own recording studio. (although I haven't found any real difference between ANY Electret Capsules) Goldmine Electronics (California) : 5 for $1.49 (limited time sale)Д¬lick to expand.I agree.

Professional Audio uses 48V phantom power. Omnidirectional electret condenser microphone cartridge Doesn't need a high-voltage bias from the outside like ordinary condenser microphones. Using the Panasonic WM-61A as a Measurement MicrophoneД¬onsists of a high voltage internal electret membrane, metal electrode and a Field Effect Transistor (FET).
