BaoFeng UV-5R Tranceiver

A friend recently sent me a link to this little gem of a transceiver on eBay. Although it’s been around for quite some time, it was new to me and, for the amazingly low price of £19, it was too good to miss. When you consider that the established manufacturers of amateur radio equipment would […]
