Anybody know what this is or does?

What about a prototype of the seismic sensors later used in viet nam to detect movement in jungle are? only thing missing is a spike on nose. just a guess?

That's what I was thinking of in my earlier post - Thanks, John. However I can't think of any examples where there was this kind of thing in W.W.II, unlike early sonobuoys and MAD for instance.

This is fascinating, like one of those collector's programmes where the experts have to identify an unknown object... wait, that's what this is!

BTY, on the sonobuoy theme, I note all the refs say they were waterproofed card or equivalent - nothing tougher or more waterproof.

It it a jamming transmitter. The T in T-96 means transmitter. A friend has a pair of T-97's. Different frequencies I guess. According to various sources it was dropped by parachute in groups to jam local communications.

A couple of sources:

A good jamming article:

If you want to part with one or both let me know. I would love them for the museum.

T-96
T-97
T-98
T-99

Ah well, at least I got close with the AN/CRT-1...

Paul,

Any information on what the frequencies were for each transmitter?

[TROJANII]

There you go! Thanks!

[RAMC181]

Sorry Taigh, not a clue.

I'd hope the info would be in the relevant manual, TM 11-512 (30 November 1944), if anyone knows where a copy could be found.

I note the example in the NMUSAF is a T-94.
Add that to the T-96 and T-97s already mentioned so far in the thread and that's halfway to one full set surviving.

All the best,
PB

Gotta say that I am always impressed with your knowledge, information and passion Paul.

Attaboy!

You're no fun, Taigh!




Seriously though, cool to know. Never heard of them, now I have.

Aw shucks Taigh,

I just do what I can to help...
I know you and others on here do the same.

I keep saying to people, I don't necessarily carry all this "useless information" around in my head (or stored on a hard drive).
The knack is knowing how and where to look for it, well, some of it at least...

All the best,
PB

This is very cool. I thought it might be some type of jamming device, but I wasn't sure.
Taigh, the owner still has it. I can ask a price if you are interested or at least hook you guys up.

Yes please

Nice bookwork!

I guess the fin-first drop is to make it tumble and violently toss out the wire before chute deploys.

[Jerry O'Neill]

Actually, the wire just falls out. It is held in place with a circular metal plate inside and the holding pin is pulled on the ground before take-off. The top (in the photo) of the unit is a wooden sleeve that just slides off very easily. The wire is coiled at the top of it and falls right out.
The parachute is stuffed inside the sleeve at the bottom. The fins slide off like the top does and then there is a small drogue chute with a spring that pops out and pulls the chute out of the container.
Pretty simple and I still have the drogue and parachute from the one I donated to the museum.
