Really frustrated with my new Flex 6400 and Maestro. I have been trying to get my Heil Pro 7 to transmit but it seems like it comes and goes. There is no profile for this particular headset and I have been trying thru trial and error to transmit but it works on and off. Far from plug and play!

Well, start with a base profile and tweak it for you and your setup, then save it. That's what we all do. Get a buddy to listen to you over the air.

Be mindful of the mic drive, when you start getting towards 0dB it starts sound bad, I run mine to peak no more than -10dB,

Ed, I am not sure if that Heil headset needs to also have the voltage bias turned on along with he +20 DB boost option, But from your comment it could need or or both of those settings,

Since you just got the rig, Lets do this , have you tried the radio only no maestro with the stock mic first, it has a profile in the mic list, I would suggest you try that to make sure all else is set correct and get some operating time with the radio and some what familiar with it. 

There is a good overview video of the maestro which my help you get things setup as well,

Hopefully someone who is using  hat headset will jump in and help you with ha basics of getting it setup, I run a Heil PR7 and can tell you it does require the voltage bias and the +20 settings, to be turned on.

Hi Ed, I have sucessfully been using the Heil Pro 7 at my remote shack. You do not use voltage bias. I will be at my remote station this weekend and I can check/send you my mic profile. My email: kari ...at....sm0hrp.se

Do you mean your trying to get it to reliably go into transmit or while in transmit to get it to produce audio drive?

Ed,  you wouldn't happen to be using one of the Heil hand held PTT switches?    They are known to be intermittent with several reviewers reporting failures including myself.  What are you using for PTT?
