All I have to offer is these 3 MPN-11 interior photos ... sources not known, so apologies for re-posting them. But I can still smell the interior in my mind!!

We had two FPN-36 radars operating at Canadian Forces Base Shearwater (across the harbour from Halifax, NS) as recently as 2008. I'm pretty sure they were replaced with something more modern since then, but I've been out of the military since 2011 and now work for National Defence as a civilian electronics technologist for the Royal Canadian Navy. I will check the dark corners of my basement; I'm pretty sure I still have my set of fold-out schematic drawings and student guide for the Quad from when I took the maintenance course in Trenton in the mid 1990's.

It was a tough old piece of kit, more washing machine than radar...

i took my training on the CPN4/MPN11 in Clinton Ontario in 1965 but worked mainly on the Quad Radar. We had a mobile airfield in Trenton Ontario with Two Quad Radars, a mobile Tower with radio techs, a mobile TACAN, mobile lighting for a 10000 ft runway and diesel generators to run everything. Lots of fun loading everything on Hercules Aircraft for deployment. Did that from 73 to 77. Retired in 86. Oh what a life.

Those both sound fantastic! I'm keeping my fingers crossed!

Many thanks.

I'd be interested to know which years those were please?

I'd also like to know when the MPN-11 arrived at Chivenor and when it was finally removed?

A while back (perhaps 2 years ago now) I heard that the National Naval Aviation Museum at Pensacola, Florida, did have an old MPN-11 kept in outdoor storage... but it was subsequently scrapped! I also understand it wasn't recorded (i.e. preservation by record) beforehand, which if correct is a travesty!

That is so sad. It seems as though the MPN-11/CPN-4 has been expunged from history deliberately!

Iím still here, though! 😎

Sad indeed... When I heard one has been preserved I was elated (and started planning a trip to Florida) , but was absolutely GUTTED beyond believe when I was told I was too late!!!! A local contact of mine kindly went there in person to ask.

I'm glad you're still there though MPN11! Any joy finding Air Publications (AP) since you last posted here???

Here is it outside the museum in 2012, behind the tail of the TA-4J. It has a very distinctive shadow! The dish is seen detached and resting on the lower trailer.

Nothing to report, sadly.

I don’t know when the radar was installed at Chivenor but I worked on it from 1972 to 1974.When the station closed and most people moved to Brawdy, I stayed and helped decommission the beast. This involved soaking almost everything on the trailer with WD-40 to loosen moving parts that had not moved in years. There were hundreds of small panels that had to be refitted to cover spaces left by removed equipment. The RN at Yeovilton, or possibly Lee-on Solent had an MPN-11 and we were visited by their radar techs who took a lot of spares away. The US wanted the radar back and in, I think August 1974 we removed it from its turntable, using a Scammell Wrecker truck, which was achieved with more brute force than finesse.

Ok, I'll have to dig into my old archives but I know I kept my old manuals and schematics of the two QUADS I worked on at NAS Miramar from 1978 to 1980. I also worked on the FPN-52 and might have those too. I went to school on the CPN-4/TPX-42 and I know I kept all my school materials. It could take some searching so if there is still interest, email me at my account email address and I'll start digging.
