So, HOW do they do it?

Recently, I looked on Amazon and saw 2 rechargeable 446MHz handsets with base chargers for just £20.39 a pair with free earphones and free delivery. That is just over £10 each with free rechargeable battery, charger and earpiece for a UHF handheld. I did not look, but there are probably less expensive ones available. These probably retune to 70cms.>

When I started designing UHF portables in the 1970s, I seem to recall they retailed at about £700 each without the chargers and earphones. I know that the level of integration must be far higher nowadays, but I am amazed anyone is able to make profits at these prices and sent them half way around the world for free!
