Heil Sound microphones and Flex, are there compatibility issues?

I was about to purchase a PR781 to plug into my 6400 until I saw that the compatibility list on the Heil web site did not include Flex. Several 3-Pin XLR mics are listed (PR10, PR20/UT, PR28, PR30, PR40, PR77D, The Fin) as compatible, but not the Heil PR781 which is reportedly designed for amateur radio use. The cable I had intended to use is Tisino XLR to 3.5mm with a separate PTT foot switch. Should I avoid the PR781? Is another Heil mic highly recommended? Thanks!

    All Heil mic’s can work work FlexRadio if you have the correct cable.

    Many use the PR781. I’m sure others will comment.

    I have the PR-40 and love it. Works great! W2IHY eq and comp, then balanced input to the Flex.

    Flex Radio sells Heil microphone adapter cables that work with the 781.
