I have one and I think there may be quite a few out here that this list may not indicate. One comment, even though it is functionally the same as tlhe Hammarlund version of the 274 , I think the sp600 is easier to tune and log stations as the sx-73 version has such a small dial with the hash marks jammed to close together! For that reason I prefer the Hammalund version.
