Hi Guys;
Someone on this reflector was kind enough to send me a manual on subject. Unfortunately the schematic is confusing to me. All the lines that cross each other have no designation as to whether they connect or just cross unconnected. Usually a schematic will have a dot where lines connect and no dot for just cross-over or a hump to designate crossover and no hump if they connect. This schematic has neither. All the cross lines look the same. I cannot tell which ones are connected and which ones just cross over. Also, there are practically no voltages given, nor the function of Q1 & Q2 which look like a voltage regulator, but what voltage? The transmitter has severe distortion. It actually sounds better tuned off the center, to either side. I suspected it was FMing but cannot prove it. The carrier is steady with modulation on a scope. I traced the audio all the way through to the antenna and it sounds good but the detected carrier is badly distorted. The voltages around Q3, the PA transistor look suspicious but I don't know what they should be. I replaced Q3 twice with no improvement. The RF injection has some very distorted wave forms but the carrier looks good thanks to the flywheel effect of the final tank. Can any one shed some light on this problem for an inept technician that does not understand his computer? Please respond off line to [EMAIL PROTECTED] . Thank you.
