Re: Ebay Lucky-Dip FRG7


 
Edited

Started again from the beginning.
1. stripped out the 2m converter, completely rewired the antenna connections and removed a pair of 1meg resisters from So239.
2. stripped the Band switch and cleaned the wipers, this made a big difference
3. cleaned the Dx/LOCAL switch again
4. mechanically aligned the preselect/Mhz and Khz dials
5. cleaned up potential dry joints
6. washed off the PCBs with IPA and inspected tracks
?
Results, much better but still issues.
Worked part way through the alignment, stopped due to scope not being up to parr.
Worked through Q101 to Q111 voltage chart, found Q110 and Q111 C&B voltages out to list, adjusted VR102 nearly 1/4 turn and they are now somewhere near, LED goes out on most of range now, but its clear there is still a problem in the selective filter area.
