You haven't experienced ham radio to its fullest if you haven't spent a weekend aligning a FRR-59  Roll Eyes

In production each module was aligned seperately on a custom built jig. Once assembled into a functioning radio the final test tech merely had to verify spec parameters.

My first job at National was in Malden as a module tweaker and I was soon climbing the walls. Luckily I was out of there in a few months when a slot opened in the Service Dept in the National Radio division in Melrose.

Lord have mercy on your soul.
I was scared of the damn thing.

It was nice to have those pullout drawers AND tilt pivots to work on either side though, AND to have the sub-assemblies you could raise from the main chassis.

Did you ever use a JRC 515 rxer?


Chuck W3FJJ has either this one or a 525.
One post-Timonium party he had, I spent hours using it and it was a very nice receiver.  That was the same fester that you and Dean-O the KNX did the Infamous Belly-Bump, do you remember ?

The NRD "felt" more like a gussied-up Kenwood R-1000 than a commercial rig.  It was better sounding than it's main competitor at the time, the ICOM R-70, a model now seldom seen on the used market. I think its descendant, the R-71, sold better so more of them are kicking around.
