Correct - the AN/URT-23 series was US Navy equipment.

Ed is confusing it with the USAF's General Dynamics (Stromberg-Carlson) SC-908 amp that went with his SC-901 receiver-exciter. These SC units were evidently predecessors to the R-1051, T-827, RT-618, URT-23, family

I have just begun a page on the SC-series at

Look at the ability of the URT-23D and later models to transmit at only 0,01 watt up to 1KW.

I presume this is for "Limited Range Intercept (LRI)" but I don't know how this works in operation? Manually or Automagically?

===========

Link-11 - HF is used to establish a net when the range between units in the net is from 25 to 300 nm. For ranges of less than 25 nm, HF Limited Range Intercept (LRI) can be used
