Best power Mic for AT-6666?

Keep the anytone stock mic but do one modification. Locate the tiny mic hole and carefully drill a hole using only a 1/8 drill bit. Before you do it. Open the mic. take off the ptt button and the spring. Then remove the 4 tiny screws to remove the board so drill bit wont damage it. Reassemble when finished. This will open the mic and allow more air around the electret condenser. Then set mic gain to about 32 and leave it. If you make the hole too big, your P's and B's will pop in audio. 1/8 is the sweet spot.

I did this same thing but went a step farther and added wind screens for cell phone mics off of Amazon. This made a huge difference and the wind screens stopped the puff pops from my breath. https://www.amazon.com/sspa/click?i...-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

Also, please note I tried a 48V phantom voltage mic like used on the Icom and it sucked compared to the stock mic with the 1/8" hole drilled and the mic wind screen. The 48V phantom mic setup would not drive it hard at all and I had to overcome the terrible noise it made through the talk back feature.

I did this to the SS9900 @32 and I get excellent reports after trying several power mics.
It's not very wide banded but provides good mid range punch working dx.
I have one power mic, it's a Cherokee handheld power mic that does sound fairly good, fatter frequency response but like Shade tree said it works against you in the mobile fighting for DX.
And the UP/DN buttons are useful mobile

Another option is just fill the inside of the mic case with foam or other dampening material. If the mic case has a lot of dead space the electret mics sensitivity picks up on that hollowness. This is a common mod on the Icom IC-7000 eletret hand mics and it really does improves tonal qualities. Plus it adds weight to those cheap feeling plastic mic cases.
