[MRCA] URT-24

[W2HX]

Alex, K2AJR found the following on the URT-24. Seems to verify that it used the T-827G (which I have).

But it doesn’t mention the amp. I am seriously guessing it was the AM-3007.  BTW the T-827G is nice (nicer than other versions) because of the front panel shift switch (170 or 850Hz) for RATT.

Anyone run any RATT/RTTY on their military equipment? Maybe we need an M&S net for RTTY!

My guess is that the URT-24 was just a lower power TX. I was stationed at the Summit NavTransFac/NAVCOMMSTA Balboa Canal Zone in the early 70's and we had HF FRT-39's and FRT-40's and the only difference was the power output. We maintained TX for Antarctica comms and supported UNITAS cruises besides other ship-shore circuits. Low power applications could be port control channels but the WRC-1 would be a better choice. The Naval Support Activity in New Orleans had a pair of URC-58's/RF-301's 2-15 MHz transceivers for port control on 3 MHz.
I haven't heard from Nick England who is more of a resident expert on the Navy Comms side... Nick your turn to chime in... 73 Tom

In my 13 years as an ET, I worked on TCS, AN/WRT-1, AN/WRT-2, AN/WRC-1, AN/URC-35, AN/URC-32 and briefly AN/URT-23 (and a bunch of other things) but never encountered an AN/URT-24.  Was it by chance just a T-827 with an AM-3007?

I was on the USS Ingram DD-938 in the mid 70's we had the WRC-1 and kept it on Hi-Comm 7X24 set to a clear HF freq that changed based on propagation, high day/low night. We would often get an Exercise White Pinnacle message via fleet broadcast and were timed to see how long it took to reply using our daily changing callsign and authentication table.
The WRC-1 served a purpose but the WRT-2 transmitter combined with an associated R-1051 was the primary TX for HF ship-to-shore using KW-7/Orestes.
The URT-23 was in Aux Radio aft in the same space as my teletype repair space, also my GQ station, also my ham shack with a Kenwood TS-520 and 4BTV mounted on the aft mast. Lucky for me my skipper was a mustang Commander and former radioman (CDR Samples -SK) he liked to phone patch home and it came in handy for patches between new moms and new dads. The URT-24 was just a 100wTX.
The 1051 was great for receiving the fleet broadcast but sucked for CW. We came out of FRAM where the comms suite was upgraded from R-390's to 1051's BUT they left two 390's on top of the MF receiver op position (for listening to AFRS-morale) so I could use the 390 for CW ops which were by then just drills and since we still had to keep the 500kc log the mill was still there along with the CW key and jack for my Vibroplex.
The WRT-1 MF TX was removed once we were no longer required to monitor 500kc and only keep a log and not required to have an MF TX capability. (If we heard a distress we sent a message with details to NAVCAMS and that was it) The T-1 was removed and a satcom station put in its place.
I was selected/directed to go to teletype school, it was a tough school and being a teletype repairman was a collateral duty on this ship and the pro-pay was next to nothing, like sea pay...
I know I could walk into the radio rooms of a FRAM Forest Sherman class tin can and fire up the gear... My RM1 was a former instructor at RM-A school and was the meanest-toughest sob RM in DESRON-14 but knew his crap, I hated his guts BUT learned more from him than anyone else. We still exchange Xmas cards and he's the old guy, not me... Funny how you remember the names of your toughest school teachers and forget the nice ones.... Hummm
