TFA blurb review
Any thoughts or edits? (I'm posting this one early because I'll be tied up with another project for almost a month starting on the 13th. I don't know when this will be promoted at FAC.) - Dank (push to talk) 21:58, 6 March 2019 (UTC)

IFF Mark II was the first operational identification friend or foe system, developed by the Royal Air Force just before World War II. The Mark I, its predecessor, had amplified the signals of the British Chain Home radar systems, triggering a radar display blip, but operators could not distinguish between an enemy aircraft and a friendly one with a maladjusted IFF. The Mark II, deployed at the end of the Battle of Britain in late 1940, fixed this problem with an automatic gain control and a system of motorized gears and cams that constantly shifted the frequency through three wide bands. The Mark II's frequencies were sufficient for the early war period, but by 1942 many more radars were in use, including incompatible ones based on the cavity magnetron. The IFF Mark III eliminated the complex gear and cam system and operated on a single frequency that could be used with any radar; it entered service in 1943 and quickly replaced the Mark II.


 * I just came across this page now. I have made a few minor edits for accuracy and removed some "inside baseball" details better left in the article. It's a bit shorter as a result. Can you check that it still reads ok? Maury Markowitz (talk) 13:15, 28 August 2019 (UTC)
 * Hi Maury, been a while. I see you're editing the 30 Sept blurb, I'll wait till you're finished then look at those edits. - Dank (push to talk) 13:21, 28 August 2019 (UTC)
