Felow Elecrafters, I have just replaced the second-to-fail .01uF cap on the KPA/100 low band filter relay circuitry of #5087. In this case, C13. Failure is a partial short which allows that relay pair (k3 and k4) to close even though U2 hasn't so ordered. Symptom that this has happened is inability to tune down SWR and power runaway. This would make sense because in this condition - particularly this one - since I don't have a 160 meter setup - the low band filters are triggered for 160 plus whatever other band I thought I was going to work, two filters for the price of one - not a bargain. This radio has suffered some hard-knocks before I understood how to deal with ESD and I feel that I owe Elecraft far more than they owe me, But......... Should I replace the relay coil caps with ones with better specs? If so, what should I use? 73 AI4TO John Ferguson M/V Arcadian **************Eat Great & Lose Weight FASTER!
