[HBR] Need advice: tuning set up for 1st and 2nd IF coils

[C Eus]

Hello to all:
I recently dusted off my generator, an Elenco SG-9500.  It goes as far down
as 100 Khz and that's it. I have a DVM that I was thinking about using to
measure the maximum output tune on these transformers.  Would it be better
to take the output and rectify it down to DC and check for a maximum DC
level (ala a rudimentary diode detector) or can I simply hook up the output
and check for max AC output? I think the DVM is a 1MEG/volt input unit so I
don't suspect this tester will load down the circuit anytime soon.

Much thanks.

Cal.
