Heil Pro 7 Headset and FLEX 6600M

WolfgangWolfgang Member ✭✭
I installed the new Heil Pro 7 Headset successfully to my brand new FLEX 6600M without any issues. Connect the supplied headset cable (3.55mm MIC and 3.5mm Phone) to the Phone and Mic plug on the back of your 6600M. Thats it and works fine. Set MIC to BIAS and +20dB - 73' Wolfgang

    Question: I am trying to do the same. Where did you get the cables (3.5 mic and phone)? What about PTT?

    HI - the MIC cable was supplied with the Headset - just plug and play. I'm using the Heil Hand-PTT Switch which I connected direct to the RCA TX1.image

    I use a Heil Pro 7 with HC7 dynamic element.  No bias. No gain.  If you are a DXer or contester then try the HC74 element.  They are easily interchangable.  Great headset for CW, SSB and contesting.  No issues at all connecting to my 6600M.  Plug and Play !

    I got my Heil Pro 7 Dynamic version today.  Plugged in and testing it with South Dakota Station with good signal report using default HM Pro mic setting.  Discovered cord too short for my operating position so ordered 6 foot extension cables from Amazon.
