WS 19 MkII jeep install questions

[James D Teel II]

All,

I’m installing one of my MkII 19 sets in my jeep. I’ve not seen any install instructions for a Jeep, so I’m just interpolating from some of the install instructions I’ve seen. For the power cable, am I correct in thinking that I need either the Connector, Twin, No. 88, or the Connector, Twin, No. 194?

I’m also going to need an Aerial Feeder Assembly, but which one?

Lastly, this set has been inactive for years, but I’ve opened it up and it looks good on the inside. From what I’ve read, I need to apply low voltage, approx 3 volts for about four hours. If nothing grenades, then I need to gradually increase the power until I get to full power, that being 12 volts. Just how am I supposed to accomplish this?

I'm not a Wireless expert, but I've been collecting the stuff for 30 years. I've heard of 19 sets being recommissioned by either using a flattened battery and gradually bring the charge up, or more professionally, with a Rheostat switch.

James,

The attached has been lying on my computer for a long time, and may be of some small use to you. Sorry, can't remember where it came from originally.

Thanks, Ron. Why'd you put your set on the off side?

Thank you, Owen. I'll add those to my reference materials. Have you seen this photo on page 108 of, "The Standardised War-Time Jeep"? What control box is this?

It's all I knew about 25 years ago when I first mounted it......I guess I must have seen pictures or something? Ron

Not familiar with that control box, but my knowledge of the WS19 is a bit limited. Maybe some of our more learned members will know? There only looks to be one connection into it, and I can't see any outgoing connections?

P.S. My father mounted his WS19 on the offside too. If you aren't fitting the charging set, I suppose having all the weight on the same side as the driver and fuel tank might make the jeep lean a bit.

The Tank Museum library, by the look of things.

That is where the illustrations in Wireless for the Warrior Volume 2 came from, and the extra detail is very helpful, particularly the part about the 'A' set aerial mounting - the variometer uses Aerial Feeder No.4 and presumably some packing washers inside the mounting (since it's intended for use on 1/2" or thicker armour plate). I have the 'B' set aerial mount if anyone needs measurements, and would be interested in getting the other one (even though I don't have a vehicle). The mountings should not be that difficult to make up if you have the measurements and some metalworking tools.

It's not for a 19 set - the Morse key is the wrong type (and appears to be the variety with a leg clamp), as are the headphones crammed into the glove box with it. I don't know enough (i.e. anything at all) about American radio equipment to guess, I'm afraid.

Best regards,
Chris.

I’ve found it. It’s a US Army J38 Morse key. The junction box mounting on the dash in the British style threw me.

Hello

The wartime CDN jeeps (MB/GPW) had various modifications for the No 19 radio set radio. The only official one I have seen documented is the one posted above.

I have never seen one modified as such in any photos other than a modern one which exists in Belgium. I cannot remember if it is original or not.

From documents we did modify 5 Jeeps to 12 volts to be used as radio jeeps. These sat in storage and were later converted back to a normal jeep. A copy of document is attached.

As the Jeeps were 6 volts, the 19 sets were powered by two batteries, which were changed daily.

In period photos these have been seen mounted on either side fender or across the back seat with the batteries on the floor or on the opposite fender. This set up was also used in Korea.

The Universal carrier was the predominant carrier for the 19 set overseas in infantry units.

I can see the desire to run them off the vehicle battery for convenience. Maybe hide the wires and place two empty battery boxes to give the proper look. They make great storage as well.

The M38 and M38A1 initially ran them off batteries as well until they came up with a vehicle power option.

Thanks

Eric

Hello

I have attached the battery box plans which were previously on this site. Cannot remember off the top of my head who made them... sorry. I do have it written down somewhere in my file.

I have also attached C42 radio installation instructions which show two batteries being used before the vehicle power supply was tapped into.

I have the 19 set installation in M38 and M38A1 somewhere, which are similar.

Thanks
Eric

Eric, the photo of the Lt in the jeep... please be aware that the radio is a WS No. 22 and not a WS No. 19.

[Eric B]

Hello Joe

Ah yes you are correct. More for showing where they were installed. We also had the WS No. 22 set installed in the same manner as the WS No.19.

There was an official Airborne standard installation for the WS No 22.

Thanks
Eric
