Quoted By:
Wouxun KGUVD1, UHF/VHF which is IP55 Dust and Water resistant and can be bought for about 80 dollars.
I power mine with 5AA rechargable batteries which are charged by a goal zero nomad recharger and battery pack.
As long as i have sunlight to recharge and dont drop it in water or down a crevice i always have a working radio.
There are better radios, such as some of the handheld yaesus which are fully waterproof for 30 minutes, but they start at 4 times the price.
