[MRCA] Speculations on ground radios and the GRC-14

Ok, so I forgot about the ARC-21/65 a big mistake. As to the technical issues would propose that the ARC-21 was produced under a cost-plus contract and being new cutting-edge technology, it will have issues.
As stated, have never had the opportunity to work on or use the R-808/GRC-14 so they may be Dogs, cannot speculate on that directly having no firsthand experience so have to go on others statements.
Completely unrelated but maybe something like the huge Heathkit Mohawk or whatever receivers Heathkit built back in the fifties. On paper they look good but am told they were real Dogs also.
More things to consider:
The ARR-41 and the ARC-38 always appeared to be related to me. Same use of a PTO, variable IF and what may be identical audio card but think the ARR-41 was released way after the ARC-38, was not uncommon to see 618T and ARR-41 living together. Often hear people referring to the ARR-41 being the flying R-390 but somehow think that's more related to the mechanical tuning system and display although do have to admit that Bothe receivers use the same Collins overdesign of lots of crystal converters.
I tend to regard the ARR-41 as a receive only ARC-38 without the mechanical SMO monster that populated the ARC-38 family.
The SMO was a truly terrifying thing, when it works it's a marvel to watch but don't think there may have been more than a handful of people who understanded its function, cams, gears and clutches.
