excuse me IF YOU READ THE OTHER TREAD ON THIS SUBJECT l have helped GRAHAM when l have all the facts l will give them to him without any prompting

The way you wrote it sounded like you were witholding the information !

HI GRAHAM

 

l have all ready found the date of issuse for 20 BT 29 will wait to see if you get any other response from other forum

members

Why don't you just tell him ?

The Chieftain did have a fuel issue that was effecting it's performance.

 

I over-took him in the arena, bearing in mind he had a 750 red top in the Mk10.

 

I spoke to Mark (the owner) and it nearly conked out a few times. He knew what the issue was and I think he sorted it by the end of the show.

 

Very nice MBT though.

What does your ARRV have in it Mark ?

This should be fun watching your CET get wet.... puddles don't count lakes do

No sorry not yet Andy, still require some of the other flotation aids from the bucket and the boom.

Just managed to purchase 3 CETflotation air bags.

He has an M747 trailer the same as mine.

Will they ever get round to restoring it... it is a bit sad if it is all hoarded away like that never to be seen again, it would be great if there is some on-going restoration happening, does anyone know ?

Fwd su co

Makes a change - numerous times (6+) we saw supposed hi vis marshalls on quad bikes doing 15-20mph with the tracked armour doing the same speed - against the rules but ultimalty dangerous and potentially lethal (pedestrians especially kids wouldnt have stood achance)

 

(yes we did inform marshalls but after the fact as unable to locate one at the time )

 

still on the positive a great new venue much easier to navigate and much improved toilets and showers

I doubt very much the 15 to 20 mph suggested, it may look like that sort of speed to you stood watching but likely to be 5 to 10 mph. At the old venue I attended on a number of occasions with CET and M578, finding someone who was prepared to walk 1/2 a mile from the camping areas in front of a tracked vehicle was difficult, near imposible.

You clearly have not experienced driving or applying the brakes on any tracked vehicles... at these sort of speeds they will stop on a pinhead without skidding like a wheeled vehicle might.

What is the walker in hi vis supposed to do, he is looking forwards where he is going he cannot see what is happening behind him, it is the drivers responsibility to observe and react to what is happening around him.

I can see no problem with a quad bieng used instead of the walker.

Back to the chargers.

Just got back from a most fantastic weekend here. It was great. I really enjoyed it and I met a few HMVF members.

great selection of vehicles, and a thank you to Marmite! For the flag, and a big thank you to ArtistsRifles for a ride round the arena in his OT90 ... Following us round was the Cromwell and to see it charging around behind us was AWESOME !!

everything was well organised , the security people were friendly and efficient. Favourite of mine were the Cromwell and a huge American breakdown truck with a superb patina.

flying display was fantastic too, and every plane did a lengthy display, which was much better than some other shows I have been to.

Cant wait till next year !

What was the "huge American breakdown truck" ? Any pictures ?

Sounding a little poorly... fuel starvation I suspect ! Still a very impressive bit of kit... great slow motion sequence ... kicking up a sand storm !!

 

 

The FV 4201 Chieftain was the main battle tank of the United Kingdom during the 1960s and 1970s. It was one of the most advanced tanks of its era, and at the time of its introduction in 1966 had the most powerful main gun and most effective armour of any tank in the world.

 

 

 

Did not pick up the fuel starvation problem ?

Really nice restoration, clearly a labour of love resulting in a well deserved award. Video was also superb set very nicely to music.

l think you my be thinking of 72 B VEHICLE DEPOT at MARKET HARBOROUGH which is near to RUDDINGTON

Evening Wally the distance between Ruddington and Market Harborough is actually 50 miles.

yes that was the purpose of the green goddess to pump water to other fire engines. I understand. the pipe on mine is well goosed, it looks like it has frozen and split in winter...two very short splits in the copper...we are going to fit an oil cooler and see how that works first, cant be as good as the cold water feed but dont like the idea of the water tank flooding into the engine again, although there is a tap to stop it doing this...but it will be forgotten I am sure so no more water cooling in the engine oil...just need to get me some new sump, rocker cover gaskets...and a new oil filter, anyone know where I can get these...oh and a new headlight lense, broken by son with wayward hammer...

Paul,

If you just want a new Goddess I know where there are 2 as released from Withams.

Wasn't sure if it was going or not

you have clearly not been invited to crew this time then Andy !

loaded up the Cromwell today and it should be down there for midday tomorrow

Who is doing transport this time ?

Is this the BID 460 installed in a SANIE ?

Normal non-encrypted rebroadcast can be done just by connecting the remote ports of a pair of 351/2or 353 radios together with D10 telephone cable and setting both radios to rebroadcast mode on frequencies at least a few MHz apart. In a vehicle with harness this can also be set up on the IB2 or IB3 interface box.

 

I had a chance last year to play with a pair of the Digital Master Units (DMU) which were used for secure speech nets. The DMU is a rather larger and older device than the SANIE and is basically just a connection box that acts as a host for the actual encryption device used with the 353 for speech traffic called the BID-250. The BID-250 fits behind the blue cover on a DMU as usually seen on e-Bay or at shows. The DMUs have come out via Withams and a few test BID simulators also came out - the real BIDs themselves must and should have been securely destroyed. If the BID simulator is anything to go by it converts analogue audio from the user's headset or a data terminal into 16Kbits/s CVSD digital audio (CVSD is a NATO standard) and in the case of the simulator feeds it to a modem to remodulate it into audio tones with about an 8KHz bandwidth - suitable for the "Wide Data" mode on the UK/VRC-353. Presumably the real BID contained crypto circuits between the CVSD encoder and the modem. Encryption Keys were input via a front panel selector and could be selected by one of the front panel switches.

 

It is also possible to build a rebroadcast for secure speech nets but that needed a further box called the IBRU (Interface Box Rebroadcast Unit) which connected to two DMUs and up to four UK/VRC 353 radios and which allowed the incoming signal from one radio to be de-scrambled and then re-scrambled to be broadcast to the other three. The fitting instructions for RT353 x 4 DMU x 2 and IBRU into Landrovers turn up on e-Bay from time to time.

 

So I think the B&W picture is of two independent 353 stations with an HF RT321 on the top shelf above it, rather than a dedicated rebroadcast setup.

 

I think the SANIE pictured at the start of this thread, if it is from BATES (an artillery fire control system usually found in the back of an RB44, I believe) is more likely to be a data scrambler than (primarily) for voice but like the DMU comprises a basically dumb box with all the connectors, switches and wires that can be fitted permanently in a vehicle and an actual crypto device - the BID - that is plugged in to the hole behind the front cover in the front panel and easily removed when not in use. The next challenge will be to find a BID 460 simulator ..

 

Hope this helps

 

Iain

I have 2 NOS rebroadcast units identical to the one in the picture above, one still in its packaging if anyone is interested.

Don't tell me both the 432s were on the same transport !

At last they have found some practical use for the most overpriced MV ever, they turned it into a log splitter !

Ask the seller ?

I think that's your computer then, I can view it fine!!

Yes we have been in touch with the website but they have no record of the person who posted the picture.

Need I say more

 

Its mine honest........ shame its not it was Mario Balotellis

Had to be somewhere near us Andy, Greater Manchester Passenger Transport Executive bus stop in the background !

It was 'The Floating Light', my maternal Grandma and Grandad stayed there on their honeymoon c. 1926.

Thanks Bob, that is how history becomes distorted, I should have verified it before I posted. Incidentally it is now completely derelict, have a look at Google street view.
