This must be a 900 maxtrac??  Don't know what other Maxtracs have 
HEARCLEAR...and it will NOT do wideband!  2.5 KHz...that's it! (maybe a 
little more)

Very few HAM's use HEARCLEAR!  Sounds compressed (because it is!).  There is 
no reason to have to use it to get enough audio.  I have no problems with 
ANY motorolas, Maxtrac(900 and UHF), Radius, GM300 etc.  Something else is 
wrong!  Check your settings!

  You will play hell trying to align TX audio levels correctly with 
hearclear on!   There is no dynamic range with it on...always full audio!


ALSO...If this is a 900 maxtrac, the rear mic connector does NOT use 
hearclear nor is it pre-emphasized like all othe maxtracs!  ALSO, the 900 RX 
from the rear (pin 11)  is ALWAYS flat regardless of JU551!  It is NEVER 
de-emphasized!  All that is done in the mic jack.  That is why the 900's 
have an extra board in the head on the mic board.  Leave the hearclear OFF!! 
If you can't get enough audio, something else is wrong.

You said you "tied flat inside the maxtrac"???  Why inside and to what?? 
The 900 maxtrac has flat audio in on the rear connector.  ALL 900 maxtracs 
are 16 pin maxtracs.

 I have 11 900 repeaters, all Maxtracs,(a couple GTX's) and do NOT use 
hearclear on any of them, and have plenty of audio!!  Never had to use the 
TXGAIN.

Since all the Maxtrac, Radius, GM300, M10, M120, GTX etc. all have the same 
basic mic input levels, I would think others would have seen the same issue 
you have.  Has to be a setting in the beagle board or one of the files.

Believe me, running hearclear only on the TX will increase all background 
noise, flutter, RF noise etc.  Unless you want to run all your receivers 
listening to it in Hearclear mode also, and that drives me nuts!  I've tried 
it!  I can identify a hearclear radio within the first sentence spoken thru 
it!  again, check your settings!


Good luck! and 73...
