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.
