11 Set stuff

[cletrac (RIP)]

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.

I received my two spare parts cases today. They both have the embossed lettering but the back side of the lid is smooth. How did that work?
I tried a wire wheel to remove the old paint and discovered the secret. The white embossed lettering is just built up paint.I can sand off the C and change it to a B. Now for a repaint job.
I have most of the case's contents on hand too.
