Another question--can you check if the distortion is also on the Aux input as well? If it is not, that narrows down the problem quite a bit. Ron N6AHA _______________________________________________

Then the problem is probably isolated to the SSM2166 mic preamp chip in the A7 section (schematic 81917_9.pdf) or its associated components, U201AA or U200A (Main Codec, schematic 81917-6.pdf). The U

FT-240-43 works for most HF and VHF applications, for the lower end of HF and BCB use FT-240-77. Same size, different mix. They're not cheap ($9.00 each), but they cure heavy duty problems that nothi

You are most likely right about that. The DSP code can change the frequency response of the system, and my measurements show the low frequency response is off quite a bit from the published specs. I

I would like to hear what their diagnosis is. I'm convinced now that there is a problem that effects only some of the O2's...maybe a bad run of chips from a 3rd party supplier. My O2, which does not

To measure frequency response of a system, the gain must be held stable, otherwise, the ALC would make every tone fed into the mic connector show exactly the same output power. That's what it's suppo

It should be a fairly simple test, and it is on most equipment, but when I put in a steady tone, the output changes. Even when the power is set at 100%, but the output is down to around 5 Watts, it w

I checked the frequency response using pink noise, and again the old-fashioned way with a sig gen, and found pretty much what I found before: - 1 dB @ 300 Hz -2 dB @ 200 Hz -4 dB @ 150 Hz -9 dB @ 100
