Hi All, I really appreciate all the feedback I've gotten from the list so far. It eases my mind that Collins, at least the newer models such as the 75S series, is not the answer to what I am looking for. I would also like to indicate here that I would like general coverage but a few SW bands such as can be had with the crystals for the 2B or the R4 series can be equally rewarding. I am also primarily interested in amateur AM vintage work with SW listening as a side interest. I also need to note that size of the receiver is somewhat important here due to the size of my operating table. It is approximately 18 inches deep, 48 inches long with a vertical operating space to the shelf I built above it of 13 inches. and I need to set a D-104 mic with the G type base in front of the receiver. I am also setting a Heath HD-1410 next to the receiver on the right with the Ranger 2 on the left. Therefore, a big receiver that is deep and over thirteen inches high would not work. This effectively rules out something like an R-390 or some of the later Nationals such as the NC-300 or NC-303. The 2B fits here very well as did the Hallicrafter SX-99 I recently sold as well as the Hammarlund HQ-110 I currently have sitting in a corner of the shack. I have a feeling the R4 would fit quite nicely here as well. With this information in mind then, I do have a few more things I need to ask the group. First, what is the major difference in performance between the R4B and R4C models? Someone mentioned the C had a 6 kHz filter one could use for AM but others seemed to feel the C isn't as good. What performance factors lead to this conclusion? Second, for those of you who have used the 2B, what is your suggested tuning method for tuning AM? Is it better to set the band pass at zero and then use the tuning dial to tune off on one side or the other; or, to zero beat the signal with the main tuning knob and then use the band pass tuning to move off to one or the other side band? Finally, if I wish to sell or trade this 2B, is there anyone on the list who wants one who might have a nice, working R4B or C who might wish to trade with or without some cash involved? This 2B is in good shape, has the 2BQ and 2AC with it and a copy of the manual. I have crystals in it for 4.7 to 5.3, 5.7 to 6.3, 11.5 to 12.1 and have a replacement crystal coming that will yield 9.4 to 10.0. I would be interested in talking with anyone just to test the waters so to speak. Thanks much all and very 73. Kevin :) Amateur Radio: K7RX
