[Amps] Checking relay timing with a scope

[Pete Smith]

I've only been doing this ham radio thing for 55 years, but until 
this year I never owned or even used an oscilloscope.  I now have an 
old 15-MHz dual trace machine that works fine, and I'm trying to 
figure out how to use it to verify the relative timing of the relays 
in my modified SB-220. Can someone explain at least in general terms 
how to go about this?
