Review: cobra M75 review - Over the last couple of years there has been a lot of talk and posting about this microphone: that its performance right out of the box is substandard and that one will need to modify the circuitboard to really make it work correctly. But I decided to buy this mic. as an upgrade for the little Uniden Bearcat 680. (An inexpensive mic. for an inexpensive radio, you know.) If it didn't perform well, I figured I'd make the necessary corrections. For the price it would be worth it. This mic. worked great right from the start. The power settings go from 0 to 10. A setting of 4 gave full modulation and a superb signal with this radio! It gives solid contacts with units over ten miles away in suburbia. So...what's the deal? Is it a good mic. or a piece of junk? I think the M75 is a good mic.; certainly for the money. But I have noticed that most of the negative postings date from around two years ago. Perhaps Cobra has fixed an initial problem and it is no longer a concern. But an equal possibility is that this mic. works better with some radios than with others. It does not appear to be a problem with the new 80 series SMT radios from Uniden. It may be just one of those things where one tries it and if it works, fine. If not, then modify it if you feel capable. Either way I think it is a good deal for upgrading the signal of any radio at a very reasonable price. Review: works great looks good - so far so good ## Features - 4 Foot Extension: When the perfect installation spot is just out of reach, this 4 foot extension solves the problem.

Now that I have it, tested it and modified it, I can say all you can read in the reviews is true. New from factory, and set in 10 (max gain) this mike was better than the original mike of my Midland 1001z but not amazing, so I googled the fix("Cobra HG M75 Power Mic fix/upgrade (+20dB gain)"), followed the instructions and transformed this not surprising mike in an Amazing one, it really make you sound louder in the air, very good reports from friends, they noticed the incredible power it deliver after the mods, now I have to use it in 4 (gain adjustment) and that is enough to make your voice rocks in the air, more than 4 will make you sound extremely loud, that's nice, more power than needed. Now I can put the mike 50 centimeters away from my mouth and still make it loud, good sensitivity. If you have a basic knowledge of electronics and soldering and you do not want to spend a lot of money in a great mike, buy this unit and make the mods!. The cable is long enough and allows you to softly extend it for more reach. Also, its design is like from aeronautic devices, it really looks good, inside the electronics components are standard and the workmanship is not the best, so I took some time more to resolder wires. Bottom line, I recommend this mike and recommend to do the mods to get an amazing microphone for a good price.I am very happy with it.
