Puxing PX-888K will get you UHF 4 watts and VHF at 5 watts for $80 USD shipped. Put it in a radio holder near the top of your plate carrier/vest and you won't have to use a headset. Speaker mic runs about $15 to $20 more. You can use all of the FRS/GMRS frequencies and any VHF you might have near you (like we have MURS here in the US.)
