You can wire up just about any microphone to a FLEX-6000 unless it requires phantom power (48 VDC) to operate, like large diaphragm mics.  People have used PC headsets, value mics from Radio Shack (when they were in business) and high-end audiophile mics.  Only your budget is the limit.

For Heil mics, if the mic is a 4-pin XLR, you need this:

For 3-pin XLR, use this:

Will they have these available at the Hamcation in Orlando or should I order them here?

As a practice, FlexRadio does not take actual products to hamfests to sell.  We take an order request that is fulfilled and shipped from Texas.

OK.  Found out my Pro 7 has a IC element.  If I change that to a H-74 element will it  work on the 6400M.

Is this the right cable to match up with the Heil 781 mic.   Says something about does not have push to talk.

Can you folks point me toward a switch that will work.  I have never had a good experience with VOX.  Too many ah's and em's.

I use a Heil FS2 foot switch at main operating position and RadioSport hand PTT switch with Maestro.

The hand switch is nice since it has a locking on/off button and a momentary button. Whichever you are more comfortable using.

Thanks Dave.  This is my first flex.  Trying to learn what works with what.  Mine should be here first part of April.

Any switch that provides a dry closure contact should work for the PTT. The cable from the switch needs to terminate into an RCA male connector for the 6000 series radios.

With that said I have read of all kinds of stuff being used for PTT, from a homemade project box with toggle switch to a sewing machine pedal.

I have successfully used electric guitar/piano sustain pedals for PTT foot switches. They are robust and invariably designed to "stick" to the floor with their weight and good rubber pads. Almost all come with a switch to change close/open on activating the pedal, and a decent long cord with a 1/4 inch phone plug. And they cost aroun $20!

OK.  Got the switch and the cable ordered.  Thought I had a switch, but could not locate it.  Probably sold it years ago at our local hamfest.

Yes, they can work, but they have to be wired properly, as noted above.
