AN/URT-3 or AN/URT-4 info?

[KD4CPL]

Anyone have a manual or own one of these beasts?
1950's Navy 6' rack synthesized autotune AM/CW/FSK
URT-3 has 4-400 final and 100 watts out - unless you have the "booster" supply/modulator to turn it into the 500 watt URT-4
Looks very similar to the SRT-14 and SRT-15 also made by Federal

Any info greatly appreciated. One of these is coming to live at my house and I need to learn care and feeding.....
cheers,

IIRC, Dale (W4AUV) had one of them or something similar. I remember hearing him describe it on the air quite a few times. I dont think he ever got it working though.

Thanks - I understand Dale had the SRT-14 that used to belong to Boatanchor Bob NA4G. I tracked that one down but it is not for sale, and I've found this URT-3 instead. I'm pretty sure the URT-3 is similar but hope to find some documentation, because a tube frequency synthesizer plus autotune is not your average xmtr design.....this is gonna be fun!

Dennis, W7QHO has one (or had one the last time I talked to him a few years ago). He had his on the air. Very cool rig with TONS of tubes.
