Hey Dave: Isn't it great to get the toys out and play? Not sure which version of the Quantum Loop you have: on mine, I tried it a couple weeks back with the power On, and the Q Multiplier really tightened up on the bandwidth. It seemed to distort the nulling ability of the SRF-59 somewhat, but if what you need is razor-sharp selectivity, the built-in Q-multiplier works great.
