What I like, and what I prefer for a base radio mic - has to be the D104/TUP9.
I got attached to the sound from hearing others on my base radio. They all have that great distinctive 'clink' when keyed up. And if the mic is in decent shape, you can key it up at an arm's length/distance from your mouth. Talking in a regular tone of voice - sounds distinctive, clear, and full of character. As far a background sound being picked up, I think that is a plus. Some guys I know have a tropical bird in their house, and it will sometimes squawk in the background. Great sense of depth; as any mic will pick reflected sounds in any room - it adds to the character of the sound transmitted - IMO. The D104 is top of the list when it comes to that.
The TUP 9 mic is also equipped with the base key switch, and I like that better than the side key D104/TUG8's. Just personal preference. Additionally, they have the same guts as the Silver Eagle; the only difference is the engraved Eagle on the back. That's about it...
But I have used a handheld D104. They sound very good - I think that is certainly one of most versatile mics around. Great on a base radio, and pretty decent if you are mobile with it - provided the car is one with a quiet ride.
If you want to go Hi Fidelity, then a Shure or ElectroVoice will be needed. Either one will make you sound like a commercial AM broadcast station - very accurate and full. Not necessarily more expensive - but quite a bit harder to find. You can always get a Shure SM56 and hook it up t your radio in the same ways that Hams adapt mics to their rigs. ElectroVoice mics might run you a $150~ if you can find one - but so is the cost of a Silver Eagle. Between the two, the ElectroVoice is a much better mic; but the Silver Eagle has character. That is the best way to say it - IMO...
