[Premium-Rx] Dangerously off-topic, diversity again

[Ka9p at aol.com]

Bob / John - 

You hit the nail on the head.  I started thinking this way when I had one 
Racal 6217's running, and spent (considerable) time and parts looking to get a 
second basket case going, when I decided that I could do a "poor man's" job with 
a pair of R4B's well before I found parts or the Racal diversity unit.

But it's not as trivial as I thought. Although the HF oscillator and vfo are 
premixed and easily slaved, the BFO is confounding me.  The circuit uses a 
transformer where the tapped primary is part of the oscillator circuit, and the 
secondary is balanced (with a grounded CT), driving two diodes in a balanced 
diode product detector - if it was single ended it would be obvious to me what 
to do, but I'm at a  loss for driving two product detectors from that BFO 
circuit - it seems if I fiddle with the primary it will screw up the oscillator, 
and if I fiddle with the secondary I'll unbalance the product detector - any 
thoughts, short of a transformer with two secondaries?  

Thanks, Scott
