Hey fellas,
Just wanted to send an update on my 555 that had low mic gain. Well,
before I sent if off to Ten-Tec for repair, I decided to see if perhaps
I could fix it. Out came the schematic and I could find nothing wrong
in the audio gain section. (mine must be a late model - it's all
surface mount components!)
So my thoughts turned to the ALC section. Well guess what was
mis-adjusted? The ALC (R21) pot, which is known as the RF power
adjustment on the bottom of the rig. Following the manual, hooked up a
straight key, adjusted R21 for 50 watts out, and plugged the mic back in.
I can now light up the ALC light with the mic gain at about 10 o'clock.
I'm a happy camper.
thanks much and 73,
ben, kd5byb
