The large group on a one week walking holiday had differing abilities so were split into two, necessitating two further guides. Over the week we used eSynic walkie talkies so the sweeper could keep in touch with the leader. Despite not being in line of sight we were able to keep in touch 100% of the time. I’ve no idea what the max range was but they were a cheap indispensable piece of safety kit. 16 channel UHF i think, similar, if not the same, as Baofeng. http://www.car4play.com/forum/post/index.htm?m=688788&v=e car4play688787 Mon, 11 May 2026 11:34:55 +0100 >> Don't mobile phones do a similar thing?

I'd be looking at Baofeng UV5r at about 15-20 quid a set. 5 watts at PMR frequencies. (and a huge spread of frequencies - might be illegal in some countries), but then so is PMR 446 in some countries. http://www.car4play.com/forum/post/index.htm?m=688774&v=e car4play688773 Sun, 10 May 2026 19:21:46 +0100 Heading back to the country still suffering a 'Special Military Operation' with a convoy of 8 ambulances in a few weeks. Last year some very cheap licence free PMR two way radios were sourced which weren't very poor as the convoy stretched a bit. I've been tasked at revisiting the comms side (shouldn't have complained :)). The PMR radios are very limited due to being restricted to 0.5 Watt output. And of course they are working inside a steel structure. Looking at whats available there are packs of radios for very little money but looking for better performance you soon get into the amateur radio sphere which require a licence. These radios will be left with the vehicles at handover. CB is a possibility which will require some wiring and mounting but doable with the cheapest kit coming in at around £60. Packs of multiple PMRs can be bought for similar money. Any experience/advice of such forms of simple comms? http://www.car4play.com/forum/post/index.htm?m=688773&v=e
