Hi there folks!
Looking for a bit of help here,I have the above radio,with a odd issue.
Firstly,there's no TX output,although the red tx light illuminates.The output stages seem fine,as when a damp finger is placed on l46 in tx mode,10 watts appears on a wattmeter,varying from 29-50mhz.Connected directly with a patch lead to another radio,a signal 9S is achieved,although just spurious noise.The PA doesn't work,either.when the PA is on,the speaker turns on,but still with the cb audio....There's very little mic audio,quiet and very distorted if you shout down it!, if you switch to ssb (still in PA mode) there's no audio at all,apart from hiss.I have had a good poke around with a multimeter,but getting no-where fast,and there's little info available in the service manual department.Anyone any ideas,or had this problem? It's a odd one,for sure.
Oh,nearly forgot,It's the PC-411AD board,with mechanical clock. Any assistance greatly appreciated !
