I decided to take my old AR240 out of retirement and see if it still worked. Much to my surprise it did work and as well as the day that I last switched it off. Of course the NiCad pack is in need of exchange but the transceiver is spot on and functions in all respects and that after 28 years of QRT. I believe that I purchased it in 1976. For those interested in serials mine has the Nr. 201316. A remarkable piece of plastic and a tribute to its Japanese manufacturers.
