There was an article in November 2005 "Electric Radio" on converting a
scope into a modulation monitor, might be a waste of a good Tektronix
scope in this case but a good use for an old Heathkit OS2 or similar.
Basically it just "sniffs" off the RF feed from the TX and applies it
to the scope via a capacitive attenuator.

To each their own, I guess, but I personally prefer to monitor the
envelope from a remote 'sense' antenna, that's fed into the front end of
the o'scope. My sense antenna for my delta loop, is a 40m dipole.
works great.
For 160, 75 and 40m, you'd need only a 20MHz scope.
