I never noticed BFO pulling on the GPR-90, but I didn't use the BFO a lot.

The "pulling" comment came from Roy Morgan, K1LKY, here on the TMC list 
in 2016:

"- You may have noticed that a strong signal will pull the BFO - that is 
tuning through a strong signal, near zero beat, the tone gets “stuck" at 
zero beat on either side of zero until you tune away a little bit. This 
is caused by some sort of feedback or leakage path front the IF section 
into the BFO oscillator.  I don’t know how to fix this. "
