Collins 390A 'tis the holy grail for a lot of folk, including me, it is said that they were engineered to a specification and not a price.
Most comms. receivers will resolve upper and lower SSB without an adaptor quite adequately, having said that decent filters and a decent product detector will enhance resolvability, a lot is to do with tuning your ears to the transmission in question while mentaly rejecting any unwanted modulation that might be breaking through.
Some comms. receivers can be a bit daunting if a person is not familiar with them but it's like any other receiver, one block at a time, most of the early ones are just single conversion superhets with a BFO and an RF amp. maybe a simple filter.
Just a few more bands and just a bit heavier...
I would recomend getting one if anyone is interested in what the wild waves are saying.
