[Milsurplus] Question ( RBS; submarine )

[Hubert Miller]

 That's one reason i really liked the URR-27 ( 100-156 MHz ) "version". I
had a really nice one; gave it to a friend. 
Never could talk him out of it, trying to get it back. Then his house
burned, and the URR-27 became iron ore again.

>To limit LO leakage, the URR-13 has a differential mixer fed by a
differential LO. Pretty smart!
