Astatic D104-M6B

great mic. had copper wire it for a rci 2985dx. sounds great and drives radio hard. only downside is the push to transmit button is tiny and digs into my thumb making it sore .

excellent mic for driving my rci 2985dx and president hr 2510. this mic rocks

I bought one of these from Copper several years ago to run on and RCI 5054 6 meter ham rig. These look exactly like a 2950 and set up much the same way. I never liked the stock mics on RCI's and this mic really brought the audio to life on that rig. The mic gain on the radio set anywhere between 11 to 1 o'clock on the knob and the knob on the mic set at about a 3 or 4 as shown on the mic and that's all you need. Great mic and think I'm going to buy another one to use on my Cobra / Uniden CB radios, can't go wrong. Excellent quality. Haven't had any problem with the push to talk switch on mine.

This M6B works good with older style radios. Got mine September this year. Using it on a 1977 President AM Zachary T radio. Good audio reports. Gives me a little more swing on the radio. That I need.

Bought this microphone in 1992 for my old orange face RCI-2950 and this microphone really makes it sing. I just bought a new M6B hand mic to go with an old HR-2510 and just like the 2950, it really brought up the audio from the stock mic. Of course, *anything* is better than a 2510 stock mic :) This microphone has an old design but it still performs great and as someone previously mentioned, it simply requires a standard 9-volt battery so you don’t have to buy a more expensive odd voltage battery the way some mic’s are designed. The old M6B hand mic from 1992 has the original black & white Astatic logo like the one pictured in Copper’s advertisement and the current M6B hand mic has a blue & red logo but both mic’s, old and new, sound exactly the same just like the one’s of yesteryear, which was a concern when I decided to buy a new one. Aside from the slightly different logo decal on the front this is the only difference. I highly recommend this microphone.
