Don,
I did not see obvious solder connection problems and have started the part 155 on page 7 in Troubleshooting. R67/R68, R66/R69 and D9 were visually checked. As for checking component values in the RF detector, I went to page 17 and am working on the table "RF Board". Have completed down through Q18. My measurement is listed last. D1 A 0 0 D2 A 8.0 7.8 D3 A8.0 7.8 D4 A 8.0 7.8 D5 A 0 0 D6 A 8.0 7.8 D7 A 0 0 C 7.5 7.1 C7.5 7.1 C 7.5 7.15 C 7.5 7.16 C8.0 7.8 C7.5 7.2 C7.5 7.2 Q5 E 0.6, 0 Q6 B 1.0,0 Q7 B 0.6,0 Q8 B 0.6,0 Q10 S 1.6, 0 Q11 E 0.0,0 Q12 S 0.0,0 B 1.3,0 C13.3,13.4 C13.4,13.4 C 13.4,13.4 G 8.1,0 B 0.6,0 G6.0,0 C 12.4,13.4 E0.4,0 E0.0,0 E0.0,0 D1.6,4.7 C1.3,0 D0.0,0 Q13 E0.6,0 Q16 E0.6,0 Q17S0.00,0 Q18G-1.0,0 B1.3,0 B0.6,.6 G2.2,2.1 S2to3,1.9 C7.5,0 C2.2,2.1 D2to3,2 D6.3,7.9 Thank you, Dale, kc9cwb Dale, Go directly to troubleshooting to locate the source of the failure - you may have to get into the Transmit Signal Tracing section of Troubleshooting (look following the tables). Once you locate the failing stage, it will be easy to locate the failing component (we can help at that point - right now all we can say is that 'It's broke' <G>). All in all, you will most likely find a bad solder connection or unsoldered connection, and the second most likely is that you will find an incorrectly placed component. So it may be a good idea to try a good visual inspection first, you may get lucky and not have to wade through the troubleshooting. When you do get into the troubleshooting, go to section 155 Power output low and follow the steps there - do not skip around (shotgunning), do things in order and your progress will be much faster. 73, Don W3FPR _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
