hi all first of ill like to thank you for becoming a part of this forum.
I play airsoft and we have a 6 man group that use baofeng radio the problem we have is that the other team use them as well and they can here our talk

Yes. I suspect your Baofengs have been programmed to use the PMR446 licence free frequencies - which sounds fine, but they're actually too powerful and have detachable antennas - which makes them technically illegal, but common. Whoever programmed them could easily add a couple of frequencies outside the PMR446 ones your other teams have and thus they'd be pretty private, unless the other teams change theirs. They'd also be illegal - but as you're working illegally anyway, you'd just be a tad more illegal. Or you could spend £75 and get a licence for them, and programme them with legit channels.

I suppose you could already be using the licence channels and paying the licence fee, but unlikely. The illegality is very common, and sort of has degrees of naughtiness. Much depends on your views of this - using powerful radios on the PMR446 channels rarely causes grief, apart from the number of channels available.

ok sounds good we only use it in the game area and was told we are covered by the site licence true of not I don't no

So they provide the radios? Then the site licence will be the channels in the radios. You could buy your own Baofengs - they start at only a tenner for the simpler ones, and with your own licence on your own channel, would be more private?

so the licence is for the channel so 6 radios on the same channel is it just 1 licence or 6 licences

It's a bit strange. If more than one user is on a specific frequency, there is a system called CTCSS which is designed to insert a tone (that you cannot hear) onto your transmission, and only radios set to that tone will hear it. This means that users who only speak from time to time - shops, offices, workshops etc can share a channel. If two talk at the same time it falls down - one will make it, or the other will, or often neither. If the radios you have been using never suffer from interference where messages get chopped up, then they will be using multiple frequencies, and they should have a licence for each one from OFCOM. If you get a licence, OFCOM will allocate you a single frequency, or just multiply the cost by the number of channels you want. The PMR446 system uses commonly 6 separate frequencies, and then puts tones on each one, making sometimes radios appear to have maybe 36 channels - the reality being that there really are just 6, plus methods to block ones you don't wish to hear. If I was a team member, then buying your own radio each, and then having one frequency licensed would seem ideal. £75 quid between the team isn't outrageous considering how much you lot spend on ammo and other kit.

Just to add CTCSS will ONLY stop other people who are using a different CTCSS on their receive from hearing you.
Anyone not using CTCSS on receive will hear you as without CTCSS on receive you hear everything that is in the open on that frequency.
Basically it is almost impossible to be totally private, just ask the Police. Their encoded digital system called Airwave has cost a fortune & was broken within a few years.
The best way to remain reasonably private is to not use the radios unless you REALLY need to. The less you send the more private you are. That may sound illogical, but the more you use a radio the easier it becomes to hear you.
In his book "The silent listener," D J Thorp describes how the British used electronic warfare against the Argentinian forces in the Falklands. This in part involved creating what felt like natural interference, so messages were sent more than once & were disrupted rather than totally jammed. This was to increase radio traffic.
Also if you look at the way that Germany's WW2 Enigma system was broken. It was in a big part due to the fact they sent everything via Enigma & they repeated messages back to the sending station. While the Americans in the Far East used Navajo's to send their messages, which meant they were not mathematically breakable & the language was very very limited in it's usage & understanding.

An after thought.
The two best ways to remain reasonably private is....
One. Spend a couple of hundred pounds each on some SSB capable handheld CB radios. These are licence free & being SSB they are less likely to be within the listening range of most scanners available to most other people there.
Two. Get a Simple, Light PMR licence & more expensive PMR radios that cover low band VHF.

77 & 86MHz are not available on the cheaper dual band radios & not as commonly listened to or used. So more likely to be semi private.

I know better ways :)

the cheapest way but not legal as you can imagine is by buying the Motorola directcall walkie talkie/phone which uses frequency hopping technology and has nice clear audio but range isn't massive so aslong as your team is closeby they would work very well .

But if your baofeng's have the scrambler function built in , which some 888 sets did then just use that for now but again on a legal aspect encryption isn't liked but will stop casual users so better than being openly heard by the other team etc .
