[arm-allstar] Treble and bass issue

[zs6xox]

Hi,

Thank you for the replies guys, appreciate it. I listened to 41288 today 
again and (just to be fair) it is not 41288 itself (great bunch of guys 
and very helpful) it is only some QSO's that have high "treble" which 
leads me to believe (as per your explanations) that only those radios 
may have their settings upside down ... ;) ... no train smash really.


I used "treble/bass" simply because those are the only two "descriptors" 
that allowed me to more or less explain what audio I am receiving ... ;-)
