RON,
 
i just installed a BE-1AM about 3 months ago, i tuned the atu for 50j0,  then 
tuned the reflected rf for minimum at the transmitter.
it's just hums along. i'm headed toward ALABAMA tomorrow or the next day,  if 
your on the way there or back i could stop in and give it a  look.

I would then read the input of the ATU at Fo and  adjust it for  50J0, 
which was all I could do on TX's that didn't have  a reflected power  
meter.

After I set the ATU input to 50J0 I  would tune / load the TX  into the 
ATU on the TX's that were  tunable.

So far the TX's with  fixed outputs (BE AM-1A etc.) have  had reflected 
power meters and I use that  to tune the ATU on CW for  min reflected to 
accomadate the whole tunnle thing  that you suggested,  which I think is 
a very good explaination for why the TX  doesn't like  50J0 at the ATU 
input.
