Found a hand drawn schematic at http://www.qsl.net/dk3red/mfj259b-sch.jpg.
But still have no time to fool with it. But do see how to make it do what I 
want if I get back to it. What I need is to have driven from an external 
precise signal source to measure SWR of a very high Q circuit ( klystron 
buncher) at around 90 MHz. The Q of the resonator is over 1000 which does 
not work very well with the drifty variable oscillator in the antenna 
analyzer. But I can still use my HP RF impedance meter when I need to make 
these measurements.
