Kaito Electronics Inc. KA500BLK Voyager Solar/Dynamo Emergency Radio - Black Review

I tested the KA500 along with several other self-powered radios for a project I'm working on in rural Sub-Saharan Africa.I found that the KA500 is a very capable shortwave receiver it's just not nearly as rugged as its competitors. Here are my thoughts:

What I like about the KA500:
- Solar Panel--the KA500 is one of the only portable shortwave receivers out there with a built-in solar panel. The panel is effective enough that it will power the radio (if in direct sunlight) without batteries and produce a reasonable amount of volume through its built-in speaker.

- The 5 LED reading lamp -- This reading lamp is impressive. If the batteries are fully charged, the lamp works for VERY long periods of time. I'm also an amateur radio operator and found that the reading lamp is bright enough that it lit up my large radio table.

- Good shortwave sensitivity -- For a self-powered analog radio, I was impressed with the shortwave sensitivity. I also found the AM broadcast and FM bands adequate/average.

- Good selectivity -- When a station is tuned-in well, you don't often hear adjacent signals.

- Good frequency coverage -- I like the fact that KA500 covers the NOAA weather frequencies, FM, AM and a very large portion of the SW spectrum (from 3.2 MHZ to 22MHz, missing only a little used piece between 8 & 9 MHz)

What I didn't like:
- Quality -- Though the radio feels solid in your hand, I found through my testing that the quality of the KA500 is actually quite poor. More than once, the tuning mechanism would slip and the needle would get stuck in the middle of the dial. The worst part, though, is the poor quality of the hand-crank mechanism. The dynamo and crank arm feel cheap. Well, they are cheap.After only a month of occasional testing--and with me being very careful with the hand crank--the dynamo started showing signs of failing. The crank became less fluid to turn and would rub the side of the radio chassis. One day, while slowly cranking, the crank arm just snapped in half. No more crank power.

- No Fine Tune control -- Kaito fits the whole SW1 and SW2 spectrum on a small dial. There were a few times I wish this radio had a fine tune control like the Grundig FR200.

BOTTOM LINE:
I sent my KA500 back and did not get it replaced. It's a shame, really. I loved the radio's features and overall performance, but was very disappointed with quality.

I could only recommend this radio to someone who plans on tucking it away and using it on rare occasions or someone who wants a basic full-featured radio but never plans on using the hand-crank.I'd also keep the receipt handy for the return (and buy from an authorized dealer like Amazon or Universal Radio).

For my purposes, I will be using the Grundig/Et

The speakers are definately an upgrade to any stock stereo. I highly recommend placing the speakers into a sealed enclosure and not just into an open hole precut into an interior panel.

Uniden Oceanus 25 VHF Waterproof Two-Way Marine Radio Review

Uniden Oceanus 25 VHF Waterproof Two-Way Marine Radio
Average Reviews:

(More customer reviews)
While I liked the features for the price, including the hailer/loudspeaker function. I was dismayed to find that the interior of my display fogged up over about 2 years. After the warranty period had expired (by about a month with no "grace period"), I found that repair (it lost the receive function on all but channel 16) would easily approach the cost of a new unit.

COBY CX-CB12 AM/FM/LW/SW 12-Band Radio Review

COBY CX-CB12 AM/FM/LW/SW 12-Band Radio
Average Reviews:

(More customer reviews)
For most people, Coby isn't the first name that comes to mind when you think of bang-for-the-buck electronics, but if ever the company had the opportunity for a turning point, or at least a shining exception, the CX-CB12 could be it. Know ahead of time that this radio doesn't break any new ground in sensitivity or selectivity - it picks up the same AM and FM stations at the same strength as any other under-$50 radio you've ever used. That being said, this radio has some big advantages.

A quick glance at the wider-than-tall analog display gives you an idea of it's expansive shortwave band coverage. There aren't any other radios in that under-$50 class that let you listen in on the 60 all the way to the 13 meter bands. Any and all of the major international SW broadcasts can potentially be received by this radio.

The control surfaces belong on a much more expensive unit - the power and band selection switches on the front move with luxury car smoothness, and the large, open tuning and volume wheels on the right side have clearly been designed for comfortable long-term listening.

Add to this incredible battery life. With only the little "Tune" LED contributing to power drain aside from the actual radio circuit (the power and band selection indicators are all mechanical), you can enjoy several hours of listening a day for literally months without replacing batteries.

Should you purchase one of these gems, you should also pick up a $10 pocket reel antenna (available here on Amazon and anywhere else radios are taken seriously), which will exponentially improve your SW reception. I have picked up several numbers stations (Google "numbers stations" if you don't know what those are) using only this $10 radio and $10 antenna setup. You won't be able to use a bare wire or large antenna, as powerful and/or nearby AM stations will flood the dial at all bands and frequencies, rendering reception impossible (yes, you'll have to spend more than $20 to hardcore DX). Accessory-wise, the included earbuds are of course cheap, but this makes sense as the purchase price should go towards the actual radio itself, not earphones. A quality set of headphones will result in quality sound.

And all of this for *ten bucks*. It's an ideal first SW set - if you or someone you know is interested in what the buzz is about shortwave, you can get your foot in the door here for the cost of lunch. At this price, losing it on vacation or having a curious youngster immolate one isn't such a big deal. It's quite possible that this is the low-cost mass-produced Model T of shortwave radios, and hopefully Coby will take note and build on this example in the future.

2.5mm (Male) To 3.5mm (Female) Stereo Audio Jack Adapter Review

2.5mm To 3.5mm Stereo Audio Jack Adapter
Average Reviews:

(More customer reviews)
It's seems (from reading the reviews) that there is some confusion about the 3 rings on 2.5mm jacks.

I notice that nobody has commented on how well this adapter works with their headset/microphone! Here is the deal; you do NOT need 3 rings for stereo! (left channel + right channel = stereo) hence two rings, plus the common ground (the tip on all jacks)to create stereo.

The 3rd ring is for a standard classic over the head, or in the ear, WIRED HEADSET with microphone, like this one:KX-TCA60 commonly used on home cordless phones. But also work on your cell phone! (with the above adapter)

A generally MUCH BETTER sounding alternative to your lost bluetooth, or the one that needs charging that you can't use right now. BTW, although a wire can be a pain sometimes, you can't beat the price, sound quality, and always ready to go device. (quality varies by model)

Here is where it gets a little tricky. Some cell phones, like Motorola, and others have a slightly different 3 ring configuration. That is probably why some customers here have been having trouble getting stereo sound.

So assuming the product itself is not defective, it is more likely your model phone is the problem. You will need to check with the manufacturer to be sure.

last thoughts: I'm constantly misplacing my bluetooth, or forgetting to charge it. These inexpensive headsets are a "must have" for us folks that can't stand holding that cell phone up to our ear all day. Or a safer way to talk when driving (where allowed) when a bluetooth is not available. PLUS they are interchangeable with cordless land lines, and you do not need to "pair" your device!
