Does anyone know which microphone element is integrated in FHM-2?

Does anyone knows which microphone element is used in the FHM-2? With my voice I have a nearly perfect match with my personal voice so It would be interesting to use this microphone element also as a headphone. Thanks in advance, Chris DM5HF www.dm5hf-chris.blogspot.com

Nobody has a suggestion? Would really appreciate an advice, also which microphone would sound similar. Background for my search is the high talkpower from the FHM-2. I do not get a similar good ratio between average and peak SSB power measured with Larrys LP500 with any other mic (condenser, electret, dynamic...) and without any distortion. Thank you very much & 73 Chris

I have been using the included FHM-2 Microphone for a year since I got my 6600M. The on air reports have been nothing but steller!! Without saying what kind of radio I am using most guess Collins Radio,, mater of fact a Collins Tube Radio from the S line!! With reports like that why change to some other microphone... My EQ is basically left at FLAT... Just retired last Friday so I am expecting the Flex to get a LOT MORE USE in the coming months!!! :-)

Hi all, Thank you very much for your answers. The background for asking is, that the FHM2 can give a constantly average talkpower around 20% of peak SSB. That means I can run 500 Watts peak by 100 Watts average SSB without any distortion (measured with LP500). Of course, we talk about a DX modulation. All of my other microphones will have distortion at this ratio - clear they are working up to 12-15%. I tested Modmike 5, Behringer B1 with 48V BIAS, Sony Electret Mic, Sennheiser PC3... Another result I got with other mics than FHM2 is that I loose talkpower (ratio) when I cut the lower frequencies. Then the ratio lowers at 10% (without distortion). The sound with cutting at 300 Hz sounds really good in playback, but for my opinion the ratio of 10 % gives me not enough punch. Also strong lowering the equalizer settings in SSDR are reducing the talkpower ratio. I hope my lines are comprehensible. Maybe I‘m on the wrong track... Now my aim is to use the FHM2 microphone element with a headset, because the hand mic is not my way talking in SSB. I got a second FHM2 and will bring the mic element to a boom. For me that would be a great solution :-) Cause I‘m professional clamped, a ready to buy solution would be the best choice. @Doug: you’re right, I also let the FHM2 for one year in the box and bought some other mics... by the way, Yaesu and Heil are working with dynamic elements @Ken: 100% tu, with equalizing I got every of my mics to sound good, but for me thats one truth, the other truth is getting talkpower with a good sounding modulation. Will have a detailed look to your clip - thanks a lot @Robert: Really cool, got really the same experience and thats why I’m so sophisticated Will appreciate a further discussion, 73 from Hamburg Chris DM5HF
