We had an old Icom A110 in the Tower. We thought originally that we'd have to fork out £850 or so for a new A120. Upon investigation, to transpires that the A110's receiver and transmitter already conform to 8.33 bandwidth. We asked Icom and they said that a firmware upgrade at about £50 (I think) would do the job and so it does. Excellent service from Icom. We spent some of the savings on a new power supply and some other gubbins (headset adaptor and PTT switch) - all good to go on our new 'channel' (which is the same frequency we had before). Locally, the Navy haven't changed, probably for the same reason as quoted by ETOPS above.
