I'm probably the last person to know, but when I was chatting to Walt, G3NYY this afternoon on 432MHz, he was telling me that he'd been QRV on 70MHz using a Wouxun KG-699E, available from China.
There's an interesting range of dual band handhelds - which looks to make it very easy to get on 144/432MHz at very reasonable prices, but the 70MHz handheld looked useful too.
You can see the details here
Reading the spec, I do wonder what the 'stun' and 'kill' alarms are!
If you don't want to use a converted PMR set for 70MHz FM and want to carry your rig around, this could be a great solution.
