Bruce P - I may have a spare rf ammeter. I'll dig through the junk bins this weekend.

All this neat stuff could be talked about in our own forum as these sets belong on many vehicles!! Right Geoff!

Bruce
That surprises me . I wonder if the tubes were made in Canada or the UK .
I was told:
ARP = army receiving pentode
ATP = army transmitting pentode ( this doesnt sound correct as it would have been a tetrode maybe )

The Aust. set has a 807 for the PA tube, ubiquitous tube.

And I agree, Geoff should consider a wireless forum (heck, maybe even include line equipment) so we don't have to hijack vehicle threads just to throw in pictures like this:

now THAT is a mouthwatering image Bruce!

I'll post whatever wireless set photo's you like (WW2 Canadian and British please, the southern half can deal with their own) in the new wireless forum...once Geoff sets up...

A new forum could be a signals forum to include all signals devices.

They are made by Canadian Marconi. The bases are stamped "Marconi" with a C/|\ and the sides are marked "made in Canada". Most have dates codes of July 1941 to October 1941. They have that spray on grey coating that is beginning to flake off.

OK .. yes the grey coating is there in lieu of the metal cage or shield that is normally used in many radios. Isn't it called a Faraday shield or something ... it prevents the stray capacity field from affecting other components in the immediate vicinity... coupling .

The British 22 and 62 sets has the same coating on the tubes... it tends to flake off .
Mike

Sounds like the signals forum is happening !

On the subject of wireless installations, here is the WS19 in my MK2. I'm open to criticism ! I'll only sulk for a short time. I also came across this bag of P clips a long time ago. I guess one day I'll work out where they all go?
Any polite suggestions? Ron

There is no hope for your W/T installation. Sulk if you like, but the only remedy is to ship the wireless set, together with the attached carrier to me. All kidding aside, great job. It looks right out of the manual and very nice. As a counterpoint, I'll throw up this worn-out and over used picture of the W/T 19 Mk.II installation in by old beast. Will post one of the 11 set installed once I get off my arse and install it.

As luck would have it
 
Yesterday picked up an original brass mast base with the cast grooves for the toothed mounting.

One less part to find or have made by Nigel

someone up above must want this carrier to come back together again...

Cheers

Well, are we going to see it :confused or are you holding us all in suspense deliberately :nono:

As Tony is always reminding us

this thread is useless without pictures

The aerial mount on the left in your picture. What is it called, and where do I get one please.

Lynn. Here is that antenna on my MK2. I'm not a wireless buff and I'm sure Mike Kelly can give far more info. This is the antenna for the B set as fitted to the earlier 19 set stations. It is fitted with a brush guard and the whip is only about 15-16 inches long? I think I'm correct in saying that the B set part of the wireless was used for short range. Maybe for talking to other vehicles in the same convoy?? As usual all these parts are becoming harder to find. But if you go through the normal channels of wireless dealers or google 19 set, something will come up. You could even advertise on this site. Ron

Philliphastings 16-06-09 06:09

Have a spare rod...
 
No not 'that' kind

Lynn I have a spare 'B' set antenna rod if you need it. They have a small thread at one end and are of a very specific length and a smaller diameter to other 'F' rods.

Cheers

Phill

Philliphastings 16-06-09 06:11

No Pic
 
Sorry Mike I have no Pic of the ant base as I handed back the borrowed camera the day before I found the base.

I am working on having pics of the carrier project posted up - hopefully by the end of the week so that Lynn can finally sleep at night.

Cheers

Phill

Lynn Eades 16-06-09 09:03

Phill
 
Yes I would like the rod thanks.
Tell me, is the floor folded at the edges, so that the floor, on the sides, and rear, are riveted to the sides and rear. Later carriers have a piece of angle iron that forms the corner, and is riveted to the flat floor, as well as the sides/ rear.
Pictures of the pedals/throttle/ gear linkage(front end) and folding rear armour would be great. Thanks Phill and Ron.

Lynn Eades 16-06-09 09:06

Phill
 
Where abouts in sunny western Aust. are you?
The reason I ask is because I am doing the Canning from north to south in July next year.

Philliphastings 17-06-09 04:39

Have to check
 
Lynn,

PM me your address and I will send off the 'B' set rod gratis.

As to the floor of my carrier, I will have to check this afternoon. The pics were already taken a few days ago but I think one shows where the folding rear plate would have been. Still haven't got them back from being burned to disc, then I can post them up one at a time while the librarian isn't looking...

Cheers

Phill

The aerial mount is unique to Mk.1 carriers sporting a 19 set. The aerial base is a standard No.9 that takes a 'G' aerial section. 'G' sections are an 18" long piece of 1/4" diameter copper rod with a No.10 screw sweated into the base. The screw is a British thread so be warned. The No.9 base has a rubber tip that can be hard to find. The last remnant is the brush guard. There's not a lot of originals of these around but I made up a drawing of one if you wanted to try your hand at a reproduction.

B set Aerial in AOP MkIIIw

Heres a picture. Not very clear.

Ron Pier 17-06-09 09:45

Hi Bruce. Have I misinterpreted your comment about the B set antenna? When you say unique to MK1. Does this mean not fitted to MK2?
Regards Ron

car_commander 17-06-09 20:09

Nigel,

I guess that I may have picked up on this thread too late. I am interested in a repro WS11 aerial base to fit a MkI Humber LRC. I don't need the carrier mounting just the No2 Base complete with spring tensioner etc.
Apologies if I am covering old ground, but I seem to be unable to view any of the attached thumbnails.

Regards,

Les.

Ron, in my UC-F1 manual it shows you where they all go, would you like me to photograph the pages ?

Ron Pier 17-06-09 22:23

Thanks for the offer Richard. I have loads of books and manuals on the carriers. That's why I was intrigued by Bruce's comment. As I said I probably misunderstood what he meant?? Ron

Bruce Parker (RIP) 18-06-09 02:56

Not sure.

What I meant to say is that the aerial bracket that bolts to the armoured side is unique to Mk.1 carriers. Bolted to the top of that bracket is the 'Aerial Base No.9' which is the tubular piece with the rubber top and is a standard 19 set base used on every vehicle or ground station that used the B portion of a 19 set. The antenna element is the 18" rod that screws into the No.9 base.
Mk.II carriers did use the No.9 base but on an aerial bracket quite different that the one used on Mk.1 carriers.

Back in 1982 , I was scrounging in HAM RADIO SUPPLIES , a very old business in Richmond . I found a box of approx. 50 of those B set rubber mounts , most had the tags on them still ..never used . I sent the last 6 to a guy in the UK a few years ago.. I gave away many of them. I have the tubular metal mount drawing somewhere ...these came in various forms to suit different vehicles .

The B set was a TUNED system, the coax leads have to be a specific length for it work, it wasn't really a practical system in field use ..too crude and fragile.
Mike

Bruce Parker (RIP) 18-06-09 03:29

Agreed
 
B sets were a 1000 yard VHF system for inter-vehicle communication and were not very good. Even under ideal conditions a good bump would knock it off frequency. The worst part was that the control unit had to be manually switched from the A set, to the B, to the intercom. All too often the crew commander would make some nice transmission to HQ about progress, then turn on the crew calling them nasty names, yet forgetting to switch from the A set to intercom only.

Ron Pier 18-06-09 08:51

Thanks for the clarification Bruce. Course I new that's what you meant all along :D Mike in the 23 odd years that I've been collecting this stuff, I've seen common place parts vanish from the face of the earth. I certainly could not now afford to buy some of parts that I obtained in the past. Ron

This is the bracket and setup Bruce is talking about. If it helps.

Lynn Eades 19-06-09 23:49

Jordan
 
Thanks for that. So where do I get the rubber bit?

Ron Pier 20-06-09 09:53

Try a google search on Sentimental Journey Militaria, os even just 19 set wireless. there is quite a bit to look at. Ron
