I also spent several years working on them, guess I left before they had the modification to the 10 K resistor. Johnson made better radios after that, the 558 was an improvement but still had the varactor diode, the 559 and 530 were my favorite.

So whats wrong with a 557? I think I have worked on more of those than any other radio in my life. In horrible places too, trash trucks, dump trucks, repeaters on Santiago Peak. Change out the 100k varactor bias resistor for a 10k, watch the ce 15 and tune away the spurs! The helical fixes all the sins! td kfi wb6mie Yahoo! Groups Links Yahoo!
