I have a Drake 2B that I refurbished and re-aligned a few months ago, and it plays pretty well on all bands. The only thing that seems a little strange is when the passband control is set to "1", and the preselector is off-tuned or if there is no antenna connected (low atmospheric noise), it sounds different than the passband control is set to "2". It's hard to describe, but it sounds a little like it wants to whistle or oscillate or something like that. Maybe a little "tinny". (It doesn't really oscillate though). Another weird thing is that it is mostly just with the AVC in "slow" position that it sounds like what I've been describing. When the AVC is in "Fast" position, Passband 1 and 2 sound a lot closer to each other. When I'm listening to stations or a high atmospheric noise level (AVC Slow or Fast), the problem, or anomaly is not very noticeable at all. I positioned the passband knob so the pitch is pretty much the same at positions 1 and 2 on all three selectivity positions, although it was a slight compromise to get them all close. I have a friend that has a 2B, and he is experiencing the same thing. I guess it's possible that they all do that, but I had a 2B back in the 60's and 70's, and I don't remember than happening. I probably wasn't as fussy when I was that young though. This isn't any big deal, but I was just wondering if anyone else with a 2B ever noticed what I described, or maybe someone with a receiver that has a similar passband control / selectable IF filter circuitry. Thanks, Al, WA2AS
