Hi All,
I wonder if any one has noticed a wild overshoot of the mic signal in the "TX Window" while transmitting.
On my Flex-5000, I see full scale excursions of the indicator particularly at the start and at the end of a transmission. The Manual says that the mic gain should be adjusted to stay below the 0 (zero) line. This occurs whether I am using VOX or MOX.
This is of concern because I am driving a Tokyo HY-POWER amplifier. The amplifier is very sensitive to any drive over 100 Watts. My output power is adjusted to 82 Watts output.
If anyone has noticed this behavior, please reply.

Robert,

I don't see this behavior, so let me ask- have you gone through your audio chain to make sure each stage is not overdriving?  There ios a good article in the Flex wiki that gives the order.  Generally, you go in order that you see the opritons in the VU display- start with a mic gain around 35, talk at your preferred volume and distance, and then set each audio stage (like EQ, compression, etc) until tthe VU continues to read between -5 and -1 dB .  If you're overdriving one stage and underdriving another to make up, you can get some wierd artifacts and generally lousy audio.
