When we were at the ground zero weekender we had a chance to chat to Yams for a bit and one of the things we yabbed about was radios. Yams showed us his Baofung handset, which is franking awesome as you can just dial your frequency straight into it. It does.work.with PMr 446 radios, although it's difficult to set up.
You can pre programme set frequencies into them for team switching etc.
Technically you do need a.licence.for.them but the times that they will be used are extremely unlikely to attract attention.
druid and I think.they are a good idea and I am toying with buying one. They area available on eBay at £25 ea and they take.a kenwood 2 pin ptt.
