If you don't fancy coming back to the UK, I attended a Canadian Advanced Operational EW Course in Winnipeg a few years ago. It was run by a USAF RIVENT JOINT Raven at the time. It was very good, and not fast jet orientated at all. Most of the other guys (and girls) were multi-engine operators.
Although 'operational', it did cover a lot of theory (decibels etc); and did stray into this theory for almost all operational anecdotes (think this was due to the instructor though!).
If it is still running, I would recommend it as an alternate to the usual courses run by the Air Warfare School at RAF Cranwell. Not to 'dis' those courses, but once you've done a couple, they do get a bit 'samey'.
Winnipeg was a good night out as well. Prob still got the details from 2007, if you want to PM me.
cheers
