Here is there info needed to address the problem:
The Audio output has an RC Filter of 100ohms and 0.1uF for a -3dB frequency of 16kHz. The boards were stuffed with 10uF instead for a 160Hz cutoff. The filter is not really necessary so the caps may be removed. If you do the rework yourself, send an email to sales@... with REWORK <order#> as the subject and we will refund $10. Or you may send the board only to: NW Digital Radio REWORK<order#> 150 Cessna Ave Friday Harbor WA 908250 We will rework it for you and refund $5 for the postage We have updated our manufacturing test to provide better coverage. Thanks, Bryan K7UDR
