When we can't get some stations to clean up their signals, why would I want
to start another controversy? I have heard stations say, "I am crystal
controlled". So if there is activity on 3.878 real wide and I start up on
3.881, what should I do?
I try to be reasonable about this, but sometimes my old hands can zero on my
755A VFO. I do promise to try though.
