When I first came on to 2m, AM was the main mode. During the 1970s, FM gradually took over. Also, the Liner-2 got people on the band with SSB. I would say the late 1970s and early 1980s was a golden age on 2m, with G8s gaining access and plenty of activity. Quite a few people used the Liner-2 and a 9 el Tonna antenna.
Although the use of AM on 2m is way down on those early dates, it can still be found. 144.550MHz seems to be the centre of activity. AM is often better than FM and narrower bandwidtth, although the RSGB "experts" seem not to know this!
Often, second hand ex-PMR AM rigs can be obtained very cheaply.
