I don't believe there is any difference, other than whether (or not) the dial is the same for the later 144s since they use a different tuning mechanism.
Hi, that's a good point, Ron. Even though the markings are the same, the slot for the tuning shaft could be a different width. I hadn't thought of that.
I will have to pull it out of the cabinet this weekend and make some measurements. Thanks!
Well, I just got back to this after a few weeks, and it looks like the dials are definitely different.
I think the hash marks and numerals for the different frequencies are identical between the 44 and 144.
However, the keyhole cutout for mounting the 144 dial appears to be much larger than than the keyhole for the 44B. I measured it at 2.32" diameter as installed.
Also, while the freq. markings are the same, some of the ancillary markings are different from those shown at Radio Daze. For instance, in the 11.5 - 12.0 MHz range, the 44 dial says "SW Broadcast." The 144 dial says "-------- SW ---------". Some of the ship, amateur, phone markings are not on the 144 dial at all.
