On Amazon Prime I noticed this UHF (446MHz?) transceiver for £11.95. Included are a charger and earpiece /mic. Another supplier has a pair for just £16.99 a pair.
When I worked at Pye Telecom we would struggle to make the charger for this price! Things have changed a lot in the last 20 years. It must be sheer hell being a UK PMR manufacturer these days. I am sure there are even cheaper ones if you look.
Assuming they ship across the world and make a profit, just how do they do it?
