Most activity in the UK is FM using modified ex-pmr gear 70.350-70.500 with 12.5kc spacing. There is still a small amount of AM activity centred around 70.260. When the bands open up or there is a contest on most activity tends to be SSB with the majority using home built transverters. Cross-band contacts with countries without 4m are usually made using the 6m band. Fairly popular amongst SOTA activators are the Wouxun 699E 4m handies usually with a J-pole or Slim-Jim made from 300 ohm ribbon cable.
