Hi all.Sorry for bad English. I have done a lot of ICOM-s but now I have problem I could not even imagine.Let me explain, unit come in for service with complain that TX does not have power at all-Spectrum analyzer showed only 10mW at antenna terminal but there was all most 1 amp of current consumption. Everything in PA checks good,I have replaced both FET-s but no awail. Old FETs from TX dead unit I have put in another u it-and works just fine.I tested PA board outside unit,driving power has been taken from signal generator,I hook dummy load before antenna switching diode----NO WAY AGAIN...Unit takes the current,but there is no power again.So far,I left the unit a side since I have many unit too fix,but I stii have no idea what possibly could be a problem... Any help and/or constructive advice are very welcome.
