Already had one responder who said the first schematic had a necessary pulse shaping element; it has an integrator (RC low-pass filter) feeding the base of the third transistor. This helps remove unwanted harmonics above the pulse frequency.
RCGroups is huge, and I already have spent too many hours reading through some of the threads. If I go missing-in-action, that may be where I'm eventually found...
