I have a bunch of Radius Mic's, the black ones with the little LED in them, Will these work on an old Maxtrac 800 Radio?

Yes, but there's a known issue of somewhat low audio when using one of those LED mic's. on a radio not intended for them.

i've got those same mic's on 2 of my x9000's and they work great there too. and they look better than the big white ones.

I also have a mic from a Saber SVA. Will they work on maxtrac's?

Saber SVA mics, if NOT the display mic, it will work just fine.

The display mics will also work, only the buttons and display will be inop.

You'll also probably see several ***** on the LCD as there is no display driver for it.....no worries though.

Actually have both. have a standard mic and a display mic

keep the display for the SVA and the standard for the maxtrac.

Robert:

Go ahead, use the Maxtrac mic, it will work just fine.

But just for schmidts and grins, check the TX audio level to see if it matches your requirements and specifications, but I'll bet you'll be good to go.

The only low mod issue I've seen with the black mic is leaving the mic plugged into a (mobile) base unit WITH a local remote. Unlike other mics, there is a B+ feed bypassing the black mic's PTT switch (check the mic schematic). Drags down Mic Hi voltage resulting in low TX audio locally and from the remote. Solution is fortunately simple. Just use a plug in the mic jack jumpered for PL.
