I'm trying to use the FHM-2 hand mic, and I'm not getting any audio out of the mic. Can anyone give me some ideas?

Tim - there are two versions of the FHM-2 mic, the version that came with the 6400 works with the 6400 and not the Maestro.  If you want to use the FHM-2 mic with the Maestro you need the Maestro version of the mic.  There are electrical differences inside the mic head. Two of us in Minnesota have been down this road, myself and K0KCY.  Open a trouble ticket as they have been helpful with both of us.  Good Luck!

Do you have the mic connected to the radio now or the maestro?? If connected to the radio make sure you have "mic" selected right below the compression meter and a profile is selected. You can't use the radio mic in the Maestro.

Hi Rex, I have tried the mic with both the Maestro, and the radio, and can't get any audio out of either one. I even tried using a RJ-45 on both ends cable and still no luck. I can key up the radio, but no audio.

Tim, connect the mic to the radio itself, then check your mic profile for FHM-2 or FHM-2 ESSB and then the radio mic settings per Steve.  That should fix the problem.  Just don't count on making the 6400 version of the mic work on the Maestro.

Why there are two versions of the mic with the same part or model number; FHM-2 is mysterious to me.  :-)

Yes as per the manual, the BIAS is used with the mic.

Yes, the mic that came with your 6400 needs bias and 20 DB

It needed the bias, but seems to work great without the +20db.

Ok, I connected back to the radio, and turned on *Default FHM-2. I also selected R-Mic on the left, and it seems to be working. I see defection on the power output now. Thanks guys. I'll see if I can make a contact now to get a audio report.

Tim,

You can also use the same mic connector that you used for the radio on the Mic2 connector, just don’t push it in all the way , just to the first notch. In the PTT connector , use a 3.5 mm TRS connector to female RCA connectors, One of the RCA connectors will key the radio.

Tim - do you have the FHM-2 mic made for the Maestro or are you trying to use the FHM-2 mic that came with your 6400?  There are TWO versions of the mic with the same model number and they are not interchangeable.  The mic that comes with the 6400 lacks some parts in the mic head that are required to also use the mic with the Maestro.  The RJ45 cable is great but it still won't convert the mic to a Maestro compatible mic.

You need the Maestro compatible version of the FHM-2 microphone.

also ... assuming you are using the 6400 version of the mic on the 6400, and the Maestro version of the mic on the Maestro, you should not need to use the +20 db setting on either piece of equipment.

Hi Rex, Mike at Flex Radio told me that the mic heads are the same. He said the only thing different is the mic cable. So, they sent me the cable for the Maestro. But, it still doesn't work. I opened a support ticket to get to the bottom of the issue. I will bring that up to them on the support ticket that I was told there is a mic head just for the Maestro, and see what they tell me. Thanks for pointing me in the right direction.

Hi Tim - Good luck with the issue and I'm sure the Flex folks with help you out no problem.  Changing the mic cord seems logical at first, but that won't get you going using the Maestro until you get the FHM-2 Maestro mic head too.  The electronics located in the 6400 and the Maestro mic head are not the same.  :-)

Seems like they just could make things compatible and interchangable instaed of making it difficult for evryone and confusing, I mean its not like its different radio manufacturers. Its so confusing even the guys at flex cant keep it straight and they deal with it everyday.

Thanks Rex, I'm sure that will be the final result.

I agree Wayne, it could be easier. They should include the radio mic with the radio, and also include the Maestro mic with the Maestro then everything would be fine. You pay enough for the radio and the Maestro, you would think they would include the mic for each of them.

Thanks guys, you all have been a big help!
