I used and serviced the RBA/RBB/RBC in the USN and use a RBB and RBC on the ham bands these days on CW and AM. The TX range from a USN ATC (later renamed the ART-13) to several boatanchors.
The RBB/RBC pair have no image problems thru 20M here using resonant antennas that make for good out of band filters and I never heard of the Radiomen aboard ship complain either and they used various long wires over salt water. With 3 tunable Hi Q stages in the dual RF amps rejection is high, think HRO-50/50T-1, NC-183, old Super Pros, SX-28/28A, etc.
A big benefit over most SS gear is no phase noise, birdies and other PLL and audio distortions....just clean signals when the TX are also clean.
On Topic: I primarily use a TS-940 or TS-950 since both have a pair of sharp selectivity filters (250 and 400 Hz) in both IF's but Im looking for the SO-1 and SO-2 optional TCXO's for both so I can run WSPR.
