So I got a pair of the "Overdrive" RK-56 knockoff mics to play with.
I was using Astatic 636L's for use in my Jeep Wrangler, which I frequently drive around in with the windows open and music blasting.
The 636L worked well, but has very restricted audio, pretty pinched sounding ,particularly bad with FM repeater use, which is frequent for me.
So the RK56 knockoffs are a LOT more natural sounding in response and have really great drive level too.
I hooked one up to a few Kenwood HF rigs in the house and also for the FT-857D, all of which have more than enough mic gain to use these mics.
The noise cancelling quality was my primary mission with better audio quality while doing it. These do the trick. If you don't talk _directly_ into these, with the lip guard literally on your lip, your audio will just disappear if you have the gain adjusted right. You should set up the gain while talking normally, pretty much against the screen. People could barely hear the music in the background at deafening levels in the Jeep, doing 70mph down the highway with the windows down. Perfect.
I didn't try it on a standard 2m/440 mobile rig though, so I can't say if they have enough output for the 2k Ohm input of an FT-7800/8800R.
I got mine here.

Have bought a few things from them so far with no issues.
