Great Radio  Time owned: 3 to 6 months
Kaito has put out a little DSP radio that is simply amazing to say the least . This radio works with two main IC's , one of the IC.s is used as a audio output amplifier , the other is used as a Digital Signal Processor . This processor works with the changing of voltages through a potentiometer tuning thumb wheel control . Each frequency band has a fixed 1% resistor of certain value connected to a slide switch to change bands . This radio looks like any other regular analog AM FM SW receiver from times gone by and it is about the size of a cell phone with a 4" screen . The difference is this radio changes frequency by voltage changes IE through a resistor connected band switch and potentiometer tuning thumb wheel . There is a big difference however as you tune you will notice a tuning noise as you pass through each single frequency . I have tried the FM band out and there are stations you can receive on this radio that can only be picked up on a expensive car radios, or other DSP radios like the Kaito KA321 . The AM band is way below average and can only pick up local stations and not many long distance stations . So if AM is your band it is better for you to buy another type of radio that will pick up AM real good . Shortwave comes in pretty good and I am really amazed at the stations it picks up . The battery life is a little under 200 hours which is great . I remember my Kaito KA 1103 which on alkaline battery's would play exactly 4 hours , and when I used the supplied rechargeable battery's rated at 1300ma it would play exactly 7 hours . The Kaito KA1103 is a little more sensitive on shortwave then the Kaito KA321 but not by much both are very enjoyable to listen to . The AM band on the KA1103 is way better then the KA321 . The FM band on both are about the same . For the price you really cannot beat the new KA321 as it can be had for $19.00 and last for almost 200 hours on 2 AA battery's . I am using this radio now as The Kaito KA1103 really eats up battery's real fast I have owned 5 of these and they all do the same when it comes to the battery life .  
Product is in production.
