> Would others please check for this condition and reply:
>
> With Version 1.372, I have headphone audio distortion from the main 
> receiver on strong local signals in the range of 59+40 dB and above.  The 
> speaker has no distortion under the same operating conditions.
>
> Prior to Version 1.372, the S-meter stopped in the vicinity of 59+35 dB, 
> regardless of signal strength.  With this new version, the meter will 
> actually hit the stops at 59+60 dB.  Ten-Tec has: "Fixed S-Meter routine 
> to correctly show signals greater than +35 dBm."
>
> The headphones are Heil Pro-Set Plus and additional resistance padding is 
> often used to help suppress QSK keying clicks.  So, I doubt the headphones 
> are the problem. Master Reset and RAM-CLEAR have not helped.
