Had an odd glitch on Saturday that crashed my HP ThinClient box that has SSD. After pulling Dandi and rebooting asterisk, it seems normal again. Anyone ever have SSD fail? Chris K7AZ Sent from my dumb-smart DROID... app_rpt-users-request@ohnosec.org wrote:

I figured out the problem : Even though I was hooking my audio directly into the mic input of the CM108 chip, a low pass filter was clamping all the high frequency signals to ground, I just had to desolder an L5 as this link shows:
I was looking at other guides, which had sound fobs with no low pass filter already in it.

I just put together a modified sound fob by taking a 10?F capacitor to the divider of 47k and 68k resistors and then to the microphone input of the sound fob, but I am getting the lack of high frequency noise error when I plug my fob into the radio. A DMK URI works fine. Has anybody else had problems with these sound fobs?
