I recently bought a Radiosport headset RS60CF with the M360 element

1) Make sure that you did not accidentally plug the 8-pin mic connector in upside down.  Some connectors seem to be able to be inserted backwards (I t seems that with the slot and tab they should not, but it has been reported to have happened.) It can happen if you plug it in under low-light conditions. 

2) Have you double-checked that you are using the MIC setting on the MIC profile?  (it shouldn't be that much of an issue with a 6300, because there is no BAL input to confuse it with, but I have seen all manner of problems)

3) Have you checked to make sure that the the Bias option is ON in the Setup tab?  
As a condenser mic, it needs the bias voltage or it will not work.

4) Have you used a continuity tester to make sure that the mic cable is wired correctly?  The pinout diagram is in the 6000 hardware manual downloadable from the Flexradio website.

I use the M360 profile with success. As Ken has said, make sure you have the proper input in SSDR enabled. You may or may not need bias. I am not really sure if you do for that element. But it can be the difference between it working or not. 

The switches I had set in my instance were those INSIDE the Y-cable junction (red circle on picture):

My cable arrived with these set opposite of what was needed in the end.

If you want to save a Default Mic Profile, you must save it with a different name.  Having the defaults as "read only" lets people go back and recover the default profile if they really get messed up.  But you can start with the default profile and modify it extensively:

Set one with more narrow bandwidth, more PROC, and high boost for DXing. (Call it "M360-DX")  

Set another one a bit wider with a little more bass and PROC = NORMAL for Rag Chewing - (Call it "M360-Rag"),

Set still another much wider with broadcast quality EQ and no PROC - (Save it as "M360-ESSB").  

The possibilities are endless.
When you master the Mic Profiles, export the Default profiles to a file all their own, delete them from your rig, and reorganize your profiles for maximum convenience, saving only the ones you use.  But remember where you stored the exported Default ones, you may need them later if you get a new mike....Or you may be good enough at fine-tuning your audio that you don't need default Mic profiles any more.

Good luck.
