What would a waveform monitor scope have to do with a timing issue with a vacuum relay? You cant use one to check the other.

It takes a dual trace scope to check relay timing.

... for some reason not many hams use a scope as a waveform
monitor.

That's unfortunate.  A scope isn't going to tell all but it
tells a lot about a signal.  They're not difficult to use
and don't have to cost a lot.  The vertical amplifier needs
to respond at least twice as high as the highest radio
frequency.  At HF, this is about 60 MHz, and a usable unit
can be found for about $1/MHz or so. Compared to the cost of
an amplifier, it's peanuts.  After I upgraded my lab scope,
I "retired" my Tek 2236 (100 MHz) to use as a TX monitor.
