[R-390] "A" Versions of Military Receivers with/without Mechanical Filter...

[ToddRoberts2001@aol.com]

Thanks to everyone for the information they have posted on some other 
receivers with the "A" suffix. Indeed there are several different examples of U.S. 
Military receivers out there with the "A" suffix that do not have mechanical 
filters. I sure have learned a lot about the R-274 series and R-1051 series here 
and that is the most fun when you can learn something while enjoying the 
hobby! Fun to learn about some of these really obscure receivers like the R649A out 
there also!  73 Todd Roberts WD4NGG.
