Wrong! Ive not only seen one but damn near crashed at GLW on landing in one from Kirkwall.
Usually in the most pleasant of wx. 50knts on the nose 30knt xwind on the western Isles in the slashing rain and she will grease on when you want to put her down firm.
Does anyone know of a contact for the disposal of the engineering infra structure ie hydralic service pump, towbars etc.

I don’t know if the Mk2 was eventually upgraded, but Tourist’s post implies the Mk2 was/is still fitted with EW190, a.k.a. EKCO Weather Radar, MEL E190 which is a cloud and clunk beast. It was also fitted, among others, to Andover, Dominie, VC10, Nimrod AEW, Andover Calibration Sqn; and to commercial airliners. (British Caledonian were a major user).
The High Power version of this (EW290) was/is fitted to Nimrod MR1, Hercules and others. Many of the LRUs are common between variants, the main difference being the higher power Transmitter/Receiver.
The link to Sea King is that the Intellectual Property Rights were acquired from EKCO (whose factory was in Southend) by what was MEL (Mullard) in Crawley, who became part of the Philips empire and, in turn, Thorn Radar, Racal Radar and Thales.
The Sea King radars you speak of were MEL products, based on RSRE specifications (that is, if MEL flogged them to anyone else, which they did, we got a cut); whereas the EW series was wholly proprietary, which makes them a very lucrative bread and butter product over the years. However, the first SK version (Lightweight Helicopter Radar, fitted to RN ASW Mk1/2) had much commonality at component level with the EW series, which puts your friend on the right track.
The RAF then fitted this to their SAR Mk3 and, when they required a weather mode, some features of the EW series were incorporated in the LWR design. This programme was cancelled at the production stage, but a handful of weather mode radars were converted.
The RN "replaced" LWR with Sea Searcher, in the Mk5. The obvious difference is the larger, flat topped dorsal radome. But SS retained components of LWR (and, hence, EW) mainly in the display sub-system. SS development was cut short by a year when the Falklands War broke out, so for some years after that what was in-service didn’t align with the spec or pubs, lacking some key features like TWS and sonics interfacing.
When the RAF MK3As were built, they surprisingly specified a hybrid of the old LWR and the newer Super Searcher, a development of SS. In short, lovely processed, colour display, but sod all targets and huge blind arc due to the old low power Tx/Rx and smaller scanner. Nobody knows why, as they were offered, free of charge, the RN’s surplus Tx/Rx etc (as the RN had chopped the Mk6 fleet numbers). The RAF also inherited the RN’s stock of LWR when SS was introduced.
Hope that little potted history explains the links. You weren’t too far away (and I’ve probably got some aspects wrong). EW190 wasn't fitted to SK, but in a design sense is part of the same family of radars.
I was led to believe by a Pilot (Ok not FAA - but he told me he was a pilot -many times over in fact) that the Jetstream had a Sea King Radar in it which I took to be of the MK6 variety and therefore I thought it may be of some use.

Fast Pussy.
There are people who are good at banter and fishing.
They are funny, entertaining and witty, bringing a welcome break from an often dry forum.
Please be aware that you are not one of these people.
Seriously.
Not even a tiny bit.

That POS known as the Jetstream was the most unpleasant aeroplane I've ever flown. Poor control harmonisation, terrible engines (in the RAF's T Mk 1) and every method of generating electricity bar the Van de Graff generator or the Whimshurst machine.
If Pusser wants to continue flying those ba$tard things, the very best of luck.
Because the T Mk 1 had such large props for its size, the slightest change in power caused pitch, roll and yaw transients. Which the autopilot could probably cope with, if it wasn't so useless.
My rule on the thing was never to close the noise levers fully until the wretched thing was on the ground. That at least meant you didn't fall out of the sky in an uncontrolled rolling motion when one of those joke French engines idled before the other.
Sodding horrible thing, the Jetstream T Mk 1. I hated all 15 hours I had to fly on it.

BEags,
fully with you on that one. The T1 was a total shed to fly. Thank god they're not still in the RAF's charge anymore.
Not flown the King Air but at least it LOOKS like it can do a half-decent job of being an aeroplane!

Ignoring the prattle from the childish boat person, as Farfrompuken has confirmed, the Jetstream T Mk 1 was an utter abortion to fly.
In fact ETPS conducted a preview on it and suggested that the C-130 would make an ideal lead-in trainer for the Jetstream T Mk 1.
