That is some awesome work.  What you guys have to go through to get everything running is amazing.  I only wish I could be closer to see it in action.  I was listening in to the RATT Net this morning as I do every Saturday morning, It was great to hear you guys on.

Yup 2368 receiver and rf-350 for transmitter. As time goes on the goal is to get our urt-23 (and urt-24) transmitters working. They havent been used in a while so I think the power supplies need some work, plus I have to chase all the cabling down to the transmitter room.

For sending we're using a cv-2460 and an ASR-28 that was completely chopped up. I fixed up all the wiring harnesses in it while a former Navy tty tech got the print mechanism working, and we swapped out the keyboard base as well as swapped in 45.5 baud gears. The plugs on the keyboard base were smashed so it was actually easier to swap the whole base since I found one. (Plug is easy to fix but has very little slack so its a pain to solder). This was a low level machine so I found enough parts to fix up the ESA box, and have a bank of "convertors" that convert the low level mil-188 to high level and vice versa. (They look like relays).

The transmitter switchboard is really chopped up so Ive been learning how thats wired in order to patch things where they need to go and maybe try to get a couple switches working.

Think they are running Harris R-2368 receivers, don't know about the transmitter.

Subject: [MMRCG] BB-62 on RATT net this morning

Today, December the 23rd at 9:45 or about this morning NJ2BB the Battleship New Jersey (BB-62) was active on the MMRCG RATT Net.  Other stations participating in today's net included N3KCB, K3TZJ, KA4RSZ, W1AEA, WA3GFZ, K8WXQ, KA3EKH and K4NYW as NCS.
First transmissions from the ship were a bit hectic being they were reversed but subsequent transmissions were all Normal and solid, at least at my QTH.
Communications originated from the message handing room on the New Jersey using original restored ASR28 teleprinters, CV-2460 and URA-17 encoders and decoders, Harris receivers and transmitters and the ships original antennas.
Jeff and the crew over on the ship have completed much work in getting the systems up and running again, a maze of patches and cross connections made difficult by the original ships de-milling process.
Think there next project is to get one of the larger “High Power” transmitters on line next.
As always I know and maybe speak for some others of us also that we are proud to see anyone go thru this work and get systems up in running that has not been used in decades.
