[Boatanchors] what superseded/replaced the R-389/URR receiver ?

[Nick England]

I don't know about the US Army follow-on to the R-389.

The US Navy used some R-389's (15-1500kc tubes) shipboard and at shore stations.
In the Navy, the AN/WRR-3 (14-600kc tubes) was pretty standard by the
late 60's. The AN/SRR-19 (30-300kc nuvistors) was also used where high
stability for multiplexed RTTY was needed. The modern replacement for
both of these was the R-2368(A)/URR which is essentially a Harris
RF-530(A) (10kc-30mc, integrated circuits).

I don't think there was any interim using discrete transistors. There
was a CV-5086 14kc-2mc converter for the R-1051, but they are very
rare and I don't know whether they were widely used.

cheers,
