     Well, I retuned it. Not a big difference but some. 
Anyway, its now the way its supposed to be. I think I am 
going to give this a rest for a while, at least until some 
new ideas come to hand. The RX works very well other than my 
concern about BS calibration.
     Another puzzle that maybe someone here knows the answer 
to, why the model number? The previous model was the HQ-120, 
the following was the HQ-140 and after that the HQ-150, how 
come this was not the HQ-130?
