  1. You are so right Tony...just tell that to the bureaucrats who oversee military museums in Canada!! .Can you suggest best forum on HMVF to give max exposure to WW II radar ? Much of the WW II kit was snapped up in the post war years and ended up in home made TV's and in ham radio shacks. Brian
  2. Hi Clive thanks for the welcome. Judging from the number of posts you fellows have racked up, there must be very little new to say on this topic. I am more of a military history buff than a valves and resistors guy. My EMERS on the Mk 6 and Mk 7 are restricted to a few data summary sheets. The No 4 Mk 6 was developed and exclusively manufactured in Canada ,whereas the No 4 Mk 7 was a British version produced many years later . My Mk 6 EMER was issued Sept 1947 and the Mk 7 EMER was issued March 1960. One has to assume that technical advances were incorporated into the Mk 7. Certainly the slotted waveguide found on the original Mk 6 was not used on the Mk 7 .The EMER refers to a Durestos cheese and reflector. A similar antenna array was fitted to the final version of the Mk 6, better known by its NATO designation AN/MPS-501B. Brian
  3. Intro to Alamotex I have lived in Canada for the past 55 years,having emigrated from the UK after working for Shell Petroleum,following my National Service in the Gunners. Service in a British Royal Artillery HAA Regt gave me my first exposure to AA radar and in particular to the Canadian built MZPI, aka AA Radar No 4 Mk 6. Some 50 odd years later I started a recreational research project looking into the role played by Canada in the development of centrimetric wavelength radar,and in particular the WW II project which resulted in the production of the GL III © AA gunlaying Radar...the very first centimetric wavelength mobile gunlaying radar to go into mass production during WW II. It was only in July 2006, that two main components of GL III © system were discovered in the open storage yard of the RCA Museum in Shilo, Manitoba, Canada. Many of the original 1940's era electronic components are still in place. These units are almost certainly the only examples of the 667 originally manufactured in Canada,(1941-5) that still exist. Funds are lacking for proper care, preservation and partial restoration. I, with the support of a few army radar enthusiasts are trying to arouse interest in getting some kind of preservation initiative off the ground. Along with this interest, pre NIKE air defence weaponry is in the mix. Thats about it. Cheers Brian
  4. No 4 Mk 6 AA Radars in line at the Weybourne AA practice camp which is now the Muckleburg museum. Single dish radars in second row are No 3 Mk 7 Fire Control AA radars. Brian
  5. Former Ack Ack gunners from my era (1950 /4) will recognise this as the Canadian built MZPI or AA Radar No 4 Mk 6. Without a close look at the antenna array, it is difficult to say whether it is from the original production run manufactured by Research Enterprises Ltd or a later version with the NATO designation AN/MPS-501B manufactured by Canadian Arsenals Ltd. If this radar was in service on the coast at Boscombe Down, I strongly suspect it was used as an Air/Sea watch radar,as were others located at AA practice camps around the coast. It was the standard TC Tactical Control radar deployed with home defence HAA Regts prior to the disbandoning of AA Command. A British version AA radar No 4 Mk 7 did go into production but I am not sure how many were deployed. An example in mint condition is in the Science and Technology Museum in Ottawa. Will try to post some photos.
