HF TransceiverIn 1982 the cheapest HF transceiver was the Yaesu FT77 at £459. In today's money this is £1486. Today the Yaesu FT450D is Yaesu's cheapest radio of similar size and costs only £589 - less than half the price.
2m HandheldIn 1981 the Icom IC2E was £159 or £559 in today's money. Today the Yaesu FT-25E is £80 - less than a fifth of the price.
CB RadiosIn 1984 I was working in Dixons and we still sold CB radios. The Harrier CB was £49 (£144 in today's money) and the CBX £79 (£233 in today's money). Today a basic CB radio like the Midland-M Mini is £60 - less than half the price.
In 1980 SSB CB radios sold for around £150 (£590 in today's money). Today a Superstar 3900, with very similar features, is £170 - around a third of the 1980 price.
Other consumer electronicsFor comparison the cheapest VHS video recorder you could buy in 1984 was £349, or £1029 in today's money. A Sony Betamax machine would have set you back £660, or a massive £2043 in today's money.
The evidence shows that radio prices are cheaper now than they were back in the early eighties which is probably why people change equipment more often.
