Stan,
The FCC shares its data on the experimental stations with Mr. Claus
himself, so I don't expect any snags here.
I tried a 10 and 20 dB drop last night, but you're right -- finer steps
would be more useful. The trouble is that with the huge swings from
fading at night, some of this will be masked. Might be a better test for
the daytime, possibly next weekend.
Hartmut has screen shots and .wav files on his web site:

Joe Taylor appears to be quite happy with the results, and spent the
evening last night looking at the two signals.
The setup here is a homebrew SSB exciter with 100 mw output into the big
Hafler amplifier. The exciter is the phasing-type, with a DDS carrier
generator. A microprocessor with keypad and 2-line display runs the DDS.
I'll have a little info on the setup on my website this week.
John A.
