the Kaito KA-600 looks fantastic. when you go to use it, it won't be.
I got a KA-500 (analog) and discovered that the solar panel isn't enough to run the radio by itself. it takes forever to charge the NiMH battery, and putting it in the sun gets the radio hot. sometimes way too hot. the worst thing about it, to me, was that it absolutely SUCKED batteries. it draws 164 mW of power, where a normal analog radio takes around 20. I would estimate the KA-500 lasts about 44 hours on a set of 3AA batteries. any other typical 3AA analog radio will last 300 hours or better. the reason why? it's not analog. it is DSP with an analog dial. and the freq stepping on SW is a ridiculous 25 kHz.
the KA-500L uses an 18650 battery. on the product page, they don't mention that it doesn't take any other batteries! you don't put in AA batteries. just that 1 rechargeable battery is all it has. nothing else. I think if they did mention that, sales would decline.
so I don't trust them.
this KA-600 radio, does say it takes 3AA batteries, but now being a digital radio with everything but the kitchen sink, must gobble batteries like candy. and I'm sure the solar panel won't run the radio by itself. the stepping is probably better than 25 kHz because they can't get away with that when people get to see what the tuner is doing on the display.
so it probably would make a nice emergency radio as long as you have AC power or a case of spare batteries.
forget about solar power coming form a solar panel on the radio. it won't run the radio by itself. and half the time it will be dark outside, and you may be inside sheltering from rain/tornados/frogs etc. without sunlight. you need a crank and rechargeable battery (600 mA NiMH is plenty) and a pack of spare batteries.
Grundig FR-200, Eton FR-350, or if you want a digital radio get one of the Tecsun pocket radios.
or, one of those Borg Johnson HS-912R cheap radios actually are the most battery efficient of all that I have tested. it's a pocket AM/FM/SW/TV that takes 2 D batteries, each of which is worth more than 5 AA batteries, so that is equal to more than 10 AA batteries. I estimate the ol' BJ should last 1600 hours. after that? pop in 2 more D batteries and keep going.
