I know this is an old post, but I have been looking into getting a couple of handheld portable radios, for use at camp and for when out on the bikes etc.
I used to be into CB radio back in the day late 70’s and things have changed a lot since then.
CB it would seem still exists, although is not in much use.
But what I have come across is PMR446 (Private Mobile Radio) legal in the U.K. and no licence required, you can buy a decent radio for as little as £20 and most come with a lithium rechargeable battery which will give a good run time, more than enough for a days usage.
But what interests me is that these new radio’s can use CTCSS which in layman’s terms means only people in your group can contact you, I won’t explain how it works but it does.
Back in the days of CB, you would often get nutters butting in on your conversation and making a nuisance of themselves, which to be fair was fine as CB radio was for all to share and I guess still is.
With CTCSS you get none of that, so that only the other person or persons you know can have a conversation with you.
OK like with CB radio, any man and his dog can listen to your conversations, but there is no way they can join in, it pretty much turns other two way radio’s radios into receiver’s only as far as your conversation goes, and if they attempt to transmit on your channel, you don’t get to here them.
Of course you can get devices to overcome CTCSS but they have to be used very close to the transmitting radio, maybe less than a meter to reveal the CTCSS code, but it’s not the sort of kit a casual PMR446 user would have with them in any case.
Just thought that I would share this, especially as some on this post, mentioned they were getting Walkie Talkies for there kids, CTCSS adds a little bit of safety.
