So guys, heres a double fix- Don sends me a rack with green slugs, so I can fix the 390A I stole the slugs from. OK-fine. So now I go back to the Collins 390A which has a poor sensitivity problem on 1 to 2mc. I try to make the peak adjustment, and I see that 2 of the slugs are cut off and sitting at the bottom of the coils. I had just pulled the 2 red ones from the original project that were incorrect. Got myself a magnet and pulled the cutoff slugs out of the Collins, put in the 2 from the Motorola, did the alignment and now running BC band with real good sensitivity. That's what I call a double fix! Got to get lucky once in a while-hi! 73s Russ. [thanks again Don!]
