Can someone tell me the difference between the Hallicrafters HT-32 and the HT-32B? I know the B has a different VFO tuning knob/window, but other than that, what is the difference? I have a HT-32 now that is working well, and have a chance to buy a clean HT-32B. Guess I am wondering if I am going to gain anything. Thanks, Jim Marshall K6OLY
