Hey 307.....got a 2950 here.....receives fine on FM, SSB, however there is very very little AM receive.....rf gain works fine on the working modes..a station usually giving me full meter comes in at maybe 3-4 "bars"...lower level stations arent heard at all. In trying to find the problem, I have replaced the HF amp(Q18 = 2sc1764 replaced with 2sc2999(nte107)).....also the front end protection diodes(replaced with 1N4148 500 ma) ...my question is two-fold...number 1....Could this be the AM detection diodes being faulty? And secondly, could the AM detectors be replaced with 1n6263's rated @15Ma? Any other thoughts on the possible problem? Thanks and 73'z from the Indiana cornfields, Shadowwalker |
