11 Set stuff

[cletrac (RIP)]

I finally found a picture of an 11 set with a calibration tablet in place then checked the holder on my set for size. The tablet would be 1 1/4" wide, 2" high, and 1/8" thick. This holder is the same size on the British and Aussie sets. It has a lot more stuff on it than the 19 set one has. Seeing as how there's a tablet No 1 to tablet No 5 listed, they must have had different markings on them. I looked in the manual again and the complete wireless vehicle setup just used tablets No 1 and No 2. Any thoughts on what would be on the pictured tablet? It looks like 3 rows of printing. I'll make a set of tablets out of white plastic then if I find what's printed on them I'll print out some decals.
I also noticed the plug and wires going to the Aerial Unit C. Those wires look to be pretty well 12 inches long. I have four ZA0933 cables that are 30 inches long. That's the wire that goes from the capacitor to the aerial on the truck. I'll shorten two of them to go from the set to the aerial unit Connector No 3 and one to go from the set to the capacitor on top of the set. I'll need another of the set end wire ends for the ground wire and I'll have those wiring setups complete with all the proper connectors. All the proper cables sure are hard to come by but I'm slowly getting there.
I still need a couple of Connectors N0 1 and the wire for my remote units.
I made a list of contents for the spare parts case using the font and format as close as I could get to Mike's post. I even made it slightly discoloured. The Ammeter HF 1 amp No 3 is the one used with the vehicle setup. The other ammeter I listed was used with the high power sets with the H.T. battery.

I've been doing a bit more research on those calibration tablets.
The No 1 tablet was used on the ground station and the general purpose vehicle station.
The No 2 tablet was just used with the general purpose vehicle station.
The No 3 to 5 tablets were just used in AFVs.
Therefore No 1 or No 2 must have been used with the Aerial Unit C and the other one must have been used with either the end feed aerial or the aerial on the truck.
I found this one image that shows part of the Aussie tablet and it's actually legible. I emailed him to see if he'd send a better picture.
That one is for truck with 6 foot rod antenna so my guess is that's the No 2 and the No 1 is for use with the Aerial Unit C.

I've come across images of three different tablets.The ground one would be #1; the truck one would be #2, and the light tank one is one of the AFV tablets.

The truck 1 Ton tablet was issued for the Australian AWA set only . Before the CMP based wireless trucks became available , the AIF and AMF wireless vehicles were normally based on the 1 Ton GS Van - usually Fords 122" w.b. . There was also a AWA tablet for the MG carrier .

That particular AWA tablet is the one that I had at one time

I checked out my Brit 11 set manual to see what the Ammeter HF 1 amp No 3 that's carried in the spare parts case was used for. The aerial ammeter in the set is used with low power and my new one is used with high power. I guess you pull one out and push the new one back in. Never tried it though. The Aussie set is the same.
I cleaned up the Brit manual I got off the net in pdf format and now I'm doing the same with the Aussie manual. I get rid of all the smudges etc, then adjust the contrast and set the image size. I rotate the pages that need it too. It ends up with a pretty good copy when I'm done.
If anybody wants copies, email me and I'll send them. They're over 50 megabites.

Many of the 350ma meters are blown up and useless because the wireless operator forgot to change over to the 1 amp meter before hitting the transmit key after switching to HP

Still more thermocouple meters are blown up because idiots 'test' them with a dry cell - even an AAA cell will deliver sufficient current to blow the nichrome resistance wire in an RF Ammeter. (After that it's completely useless since there's no damping on the movement - it relies on the circuit of meter coil through thermocouple to provide the damping, so you can't just add a shunt or series multiplier and repurpose it as a 'normal' DC amp or volt meter.
