Kaito KA1102 AM/FM Shortwave SSB Radio, Black Review

Kaito KA1102 AM/FM Shortwave SSB Radio, Black

This is my fifth Kaito portable radio and it is indeed an excellent product. It seems extremely well made and should last a long time if treated with care. The radio is both very small and readily transportable yet the reception is still excellent on all available bands.
I especially like being able to change the AM(MW)/SW narrow/wide (bandwidth) filter setting, the DX/local RF gain switch as well as the news/music (narrow/wide) filter switch in order to improve reception of any desired signal. Using the SSB BFO fine tuner on page 9 is also very easy and straight forward as well. The ability to step tune with very small increments on pages 7-9 is also excellent in my opinion once a signal of interest has been located.
I also really like the highly useful system of storing presets with the ATS system on page 0 and then being able to use the copy command to transfer them to other pages after they have been thoroughly edited into a useful list.
I also really like the very pleasant blue backlighting system on this radio with ALL buttons as well as the LCD screen being nicely illuminated. This is especially useful for nightime listening while going to sleep.
I didn't think that I would like the digital volume controls before I got the KA1102 based on other digital volume controls that I have tried previously, but I have totally changed my mind on this very nice feature. The steps between each setting are sufficiently small that very precise control of the volume levels can be attained, especially when using earphones which is my most common mode of operating this radio. In addition however, since the volume controls are totally digital, the common problem of accidentally turning an analog volume control knob and thus changing the volume level significantly from the last use of the radio is no longer a problem at all. Too many times my ears have suffered from not properly checking an inadvertent change of the analog volume control knob setting on other radios that I have used!
In addition, several people have complained about the poor English Kaito/Degen manual, but if you can't figure something out, just download the Grundig/Eton G3/G5/E5 manual (based on the recent reworking by Grundig of the poor ergonomics of the Kaito KA1103 radio) where all other relevant details are readily explained. Grundig/Eton has recently significantly changed the fine manual that was available online until February 2008, but the new manual is still better than the Kaito manual for providing many explanations for poorly explained features.
The unavailability of the LW bands on this unit is something that should be rectified by Kaitousa (pun intended) at some future date (although the Kaito KA1103 was introduced to make that specific correction among others).
Also a screen version of the signal strength meter (now done using 4 red LEDS, except in FM stereo mode where only three LEDS are used for an indication of the signal strength- see also below) should also be added as well as an indication of the DX/local switch setting.
One additional idea: Kaito should make future editions of this radio so that the internal AM/MW ferrite antenna could be disconnected from the system and replaced through the external antenna jack by either an indoor or an outdoor antenna for even better AM listening (UPDATE- 5/06/2008: This am antenna decoupling has now been done for the Grundig G5 made for Grundig by Tecsun/Degen, the Chinese parent company for all Kaitousa products. The G5 is the updated and more expensive version of the KA1103 with all its odd ergonomic problems corrected including the famous volume control problem). Kaito still offers an antenna that inductively couples to the internal ferrite AM antenna along the top edge of the radio, but that is a clumsy way to get even better AM reception in my opinion since there is no easy way to attach the coupler directly to the radio.
Finally, the choice of listening in the stereo FM mode seems to be presented redundantly (twice) on the KA1102 by the presence of both the 4th small red LED below the LCD screen and by an indication on the LCD screen itself (through the symbol, ST)?
I look forward very much to having the fun of using this radio for the very high quality sounds of music, news and just general shortwave listening from all over the globe for a very long time.

Kaito KA1102 - Portable radio Review

Kaito KA1102 - Portable radio
Average Reviews:

(More customer reviews)
Built in a factory in China famous for its radio electronics, the Kaito 1102 has become a beloved radio among techies and radiophiles alike for many reasons. Open it out of the box and you'll notice it's tiny, smaller than a thin-sliced sandwich. Its silver, modern exterior looks as updated as any new Sony or Sangean or Grundig. Then place it against its competition, the Sangean 505 (about 20 dollars more), the Sony ICF SW35 (about the same price) and you'll notice that the Kaito beats the other two for different reasons. First, the Kaito and the Sony 35 have similar, strong reception, on both AM and FM, but the Kaito wins because it has a vastly far superior speaker, crystal clear and capable of good sound for this type of radio. The Kaito and the Sangean 505 have similar good speakers but the Kaito has better reception, especially on AM. My only complaint about the Kaito is the owner's manual which has five different ways of showing you how to use the presets and the "pages," and only one of those instructions (I found out two hours and much trial and error later) is accurate. You must press the M/Lock key to activate your preset option and for some reason the manual only makes this vaguely clear in one of its instructions. But if you don't mind fiddling with the controls and scouring the manual with a patient eye, you'll find yourself in possession of a gem and discover why so many techies consider the Kaito 1102 a real buried treasure that stands up to the far more expensive Sony 7600 and Sangean 909.
Post Script: In the ensuing months I've bought the lesser priced Kaito 1101, almost identical to the Kaito 1102, and have found that the 1101 gets even better FM sensitivity. Many have expressed the same experience with the Kaito 1101. Thus I must conclude that for a PLL synthesized portable radio with presets, the Kaito 1101, which cost me thirty dollars less than the Kaito 1102, is the king of digital portable radios.
Update: In spite of its awkward ergonomics, which include two-step preset choice and strange push-button volume control, the Kaito 1103 amazingly gets even better reception than the 1101. The 1102 is last of the three but has the best ergonomics.

Kaito AN-03L - Radio antenna Review

Kaito AN-03L - Radio antenna

From what can be seen on the Amazon website as well as on other sites, this Kaito reel antenna (AN-03L) is essentially the same as the Sangean ANT-60 antenna (and 50 % cheaper in price!) right down to the supplied connector for a whip antenna (for radios without an external antena jack of any kind). The only notable, albeit quite small, differences are the presence of two separate finger holds used to reel the antenna back up when finished listening and a separate small attachment for hanging the unit up on a hook in the wall or on the ceiling, etc.). This Kaito antenna is designed to improve reception on FM/SW as well as for TV (UHF/VHF) and for the Weather bands for any such radio. AM (MW) reception is separately controlled by a ferrite antenna coil that is comonly incorporated inside of most radios. I have used this Kaito antenna on my Kaito KA1102. The antenna is 7 m (~23 feet) long which should usually be placed as high as possible near an outside door or window of any building for the best reception improvement. I have found an excellent improvement for weaker signals on the FM/SW bands (too long of an antenna can overload some radios like the KA1102, but this length of wire is perfectly adequate whereas other longer external antennas will not be. Always check your radio manual first before investing in a very long external antenna!). It must be remembered that the antenna not only allows an amplification of signal, but also of the prevailing background radio noise level so if it is very noisy at the time of reception at a certain frequency, the improvement in "hearing" may not always be as good as at other times when the background noise levels are much lower. Overall I am very happy with this very inexpensive purchase which is a simple passive fix for a generally quick improvement of signal strength for the weaker FM/SW radio waves.

Kaito KA1103 - Portable radio Review

Kaito KA1103 - Portable radio
Average Reviews:

(More customer reviews)
I own the whole lineup of Kaitos and the 1103 beats the others for FM sensitivity. The 1101 takes second, the 1102 takes third, and the 105 takes fourth. AM is similar on all models. But the speaker is also superior on the 1103.
Here's what I like about the 1103:
1. Powerful, crystal clear FM reception that is superior to radios that cost twice as much.
2. Warm full speaker sound for a radio of this size.
3. The cool factor of a radio that has so many innovations and is changing the radio industry, causing Sangean, Grundig, and Sony to wake up and start making more competitive products at better prices.
4. PLL synthesized tuning with over 250 presets or memories.
Here's what I don't like:
1. You have to press buttons or digitally enter for volume control. There is no spin wheel for quick volume change.
2. The analog display takes up unnecessary space on the radio.
3. AM, like all PLL synthesized radios, is well above average but needs improvement.
However, AM is more than adequate and as a whole the 1103 is my favorite PLL synthesized, dual conversion small radio. If I could only own two radios, a compact and an analog medium sized radio, I'd keep the Kaito 1103 and my Tecsun BLC 2000 (sold for considerably more as the Grundig S350), which gets great AM.
If you don't mind finding an English manual on the internet, you can spend half the money on the Kaito by buying its clone, the Degen 1103. Degen radios, the original Chinese versions, are Kaitos but only come with Chinese manuals and they need AC adaptor converters. The upside is that they are half the price of the American version Kaitos.
Post Script: I enjoy my Kaito 1103 more than ever because I placed it ontop of my Sangean WR-2 and hooked up an audio cable between the two radios. So I'm feeding the sterling 1103 reception through the Sangean's premium speaker. Great bedside setup. You could do the same for cheaper by just buying a good speaker and hooking it up the 1103.
Update: I don't recommend you save money by purchasing the less expensive Chinese clone Degen. The adapter gets hot. If you must get the Degen, buy a USA-built step down 110 converter to avoid fire hazard.
Update for 8-12-206: Both my Degen and Kaito 1103 have shut down making me think that they had lost all electric power or had "fried" inside but in fact they had "shut down" and only needed to be reset by sticking a paper clip end into the reset hole. Now they both work fine. In fact, I bought the Kaito because I thought my Degen had "fried." I was wrong. Keep in mind, these radios can be a little touchy and may need to be reset from time to time.
