There may be many reasons for the same symptom. In mine, the power decreases intermittently to a very low value, then ERR TxG appears. It all clears by itself in 5-60 min but then reappears again. Reinstalling LPA cleared the problem for 2 months but now it is back. I found recently that the power comes up when when I shake the radio. So it must be intermittent connection in PRE-LPA stages. Following Gary's advice I am going to do some troubleshooting but it is not easy because the condition occurs intermittently. Ignacy
