Hi Robert. The only opera unit I have it the Dynamotor, and the unit what you see. The dynamotor has the connectors with it/. Its a perfect set and would look great next to the BC-348 I sold you. I didn’t know you were an Air Force Dentist. They petrified me as that is where you you had your blood pressure taken pryer to your dental appointment. Mine was Sky Hi, I was able to seat around it until I got to Sembach. The Captain Dentist I think figured out whet I was doing and Marche me up stairs to the Doctors. I figured I had better go with him as he would just get colonel to march me up and then I would be in trouble. It sounds like your doing well after your procedure/surgery. I am very glad to hear that. Have a great trip to Italy and Have a margarita Pizza for me. 73, Bill Busch.

The MIL-S-901 heavyweight test, also known as the barge test, is perhaps the most well-known test in MIL-S-901, mainly because it involves setting off explosive charges near a standard or large floating shock platform (FSP) that houses the item or equipment being tested.

According to the MIL-S-901 heavyweight test schedule, a 60-pound explosive charge is detonated at a depth of 24 feet below the water’s surface for the standard FSP test, while a 300-lb charge is detonated at 20 feet below the water's surface for the large FSP test.

I'm no expert on anything, but I'm under the impression that the radio equipment I've seen installed in naval combatants has some pretty hefty shock mounts to improve survival through torpedo and enemy naval cannon hits on a ship, not to mention firing of the ship's own large weapons. I seem to recall that even the 5" guns hit you like a plank on board. The ringing pulse of a hit throughout the steel structure is apparently pretty big, and those ATC and ART-13 transmitters have some fairly sensitive inner parts.

There are some folks on MRCA who can interject some better facts than my meager impressions.

Mike is, of course correct. The TCZ nomenclature is strictly Navy. I can only imagine that they may have been shipboard, or maybe shore stations at NAS facilities. Yet, the only place I've seen them were at 3 different MARS stations. All gleaned from DOD R&M and such, I assume. I tried to use a TCZ mount kit on a shoeless ART-13 but guess I was missing something.... Ted, W3PWW had all the poop on the TCZ... but....

In addition to Jeep's description, I don't know of anywhere in the Signal Corps inventory that the TCZ was used. It had that salt water Navy aroma, don'cha know. (running and ducking...)

In order for it to be used in an aircraft or ground vehicle it would have needed another pair of support plates underneath with appropriate rubber shock absorbers. You can see the two ART-13 transmitters in the Enola Gay (one connected to the "liaison" antenna, the other to the "command" antenna) at https://aafradio.org/NASM/Enola_Avionics_Descriptions_-_Radio_Op.htm(showing that both have the standard MT-284/ART-13 shock mount with rubber pads separating the three levels of the mount.) A better closeup of the MT-284 mount construction is at the top of https://aafradio.org/garajmahal/ART-13_mounts.html

The TCZ was simply a ground mounted T-47. It sat on a 44" (nom) cabinet with an a.c. power supply. The mount was designed to support the transmitter in a fixed environment. I saw several in USAF MARS stations...back when....

Hi Jeep, educate me. What was a TCZ mount for? We know the army used it in the Enola Gay. Did they use it in vehicles installations?

Thanks, 73 Wild Bill, K0IKP

Looks like the TCZ mount vice the aircraft shockmount version. Very nice unit!!
