Hi All
Thanks for the suggestions.  It does behave much more as I expected when properly terminated with a 50 ohm resistor across the probe.  I believe the tx input impedance is around 47 kOhm so I'll try coupling it with a 1:1000 transformer and a 10nf capacitor in series between the transformer and the tx input roughly where the xtal now is.

Curt- that's for that link.  Great site and lots of stuff I didn't know.
