KAITO 1103 old or new versions?
I've just bought a slightly used 1103 (looks like unused), and can't
figure out which one I've got. The guys said it's a 2006 version, but he didn't have anything with date of purchase - any receipt, or anything. I've read a lot before choosing 1103 over Sony 7600 (costing twice as much and not any better). My 1103 does have "shuffling" when rotating the tuning jog-dial - light "blip-blip" in quiet sections of MW and SW. It is barely audible, and in noisy sections of SW I don't hear it at all. I've read that this defect has been eliminated after March 2005. Q1: Anybody has this "blip-blip" on his 2006 model? Is there anything else that makes the latest 2006 models different from earlier ones? Other than that, I'm satisfied. Functions are almost intuitive. Some buttons are too close to each other, and I would like them to be larger too. My apartment i is a RF nightmare - downtown Vancouver (Canada), wooden building, but few hundred yards from railway depot and some industries, and mountains all around. So I'm not surprised to hear so little on SW. Just a few stations with a so-so quality here and there, in 41, 49, and 31 m bands. MW is astonishing - not only I hear a bunch of them in neigboring Seattle 200 miles away, but also as far as Texas and San Francisco, - more than a thousand miles away. Wire antenna doesn't change much, even when hanging out on the balcony. Time and the last listened station are lost if you un-plug it or remove the batteries - it returns to the deafault loud 40 level volume and to FM band. But pre-set stations remain in memory. Q2: I am confused about its "100-300000 khz continus coverage". Bands on pseudo-analog dispaly are not overlapping. For ex. low AM ends at 520 KHZ. If I dial 519 and go down, it apperas to tune to 519, 518 etc. But if I dial, say, 140, it displays 140, but tunes to 1040 AM (MW). Anybody noticed this? |

Try having a set of recharged batteries on hand. Replace them immediately
after removing the spent batteries and you won't have this problem. wrote in message ups.com... Time and the last listened station are lost if you un-plug it or remove the batteries - it returns to the deafault loud 40 level volume and to FM band. But pre-set stations remain in memory. |

Maybe you are implying/suggesting that the manufacturer went through some type of a major engineering change somewhere during the development cycle which produced a significantly different radio. I have heard that there was something different with the antenna circuits when plugging in an external antenna that changed along the way. I think my radio acted differently from the schematic that was posted to Degen group. It would be nice to have a list of engineering changes that took place along the way, but not likely with a radio made in China. 73 NEO The most comprehensive description of the KA1103/DE1103 appears to be on the Russian Radioscanner forum. There is a compilation of material on modifications by someone by the name of IRIS, a crude, computer translation of which is available on the main English language forum at http://groups.yahoo.com/group/de1103/ in the Files area. It reports a difference in the antenna input and one or two internal changes that are obvious when opened up. However, this was a revision in effect after October, 2004. Whether there has been any subsequent revision has not been reported or, at least, is unknown to me. The antenna input change may be detected by an external test. Tune to a weak VHF-FM signal. insert a bare 3.5mm plug into the antenna jack. If the signal decreases, you have a post Oct/2004 model, otherwise an original one. The newer one disconnects the telescoping antenna when an external antenna is plugged in; the older model left the telescoping antenna always connected. Tom |

Tom Yes, the Russians - iris have done a very nice job of supplying info for radio. thanks NEO |

Yes, that's what I've heard. Russians on their forum (as much as I could understand) are talking about 2 versions of circuits in Degen 1103. But may be it was only change in external antenna commutation somewhere in 2004. The most comprehensive description of the KA1103/DE1103 appears to be on the Russian Radioscanner forum. There is a compilation of material on modifications by someone by the name of IRIS, a crude, computer translation of which is available on the main English language forum at http://groups.yahoo.com/group/de1103/in the Files area. Yes, thanks - and here is "normal" English translation, edited by some american user: http://www.radioscanner.ru/receivers...n1103_eng.html . IRIS has done a great job - very detailed review, not just a compilation. There are, as I understand, other his publications on modifications made by IRIS and other users (not by the factory) in Degen 1003, but this requires knowledge of Russian. Dan Say, - thanks for the link to Ontario Dx website. Now that I knew where and when to look for, and got rid of AC adapter on SW - using batteries instead, as my friends suggested, and stepped out to the balcony - I think SW works fine for my particular location. Yesterday late evening Radio Australia was more-less where it should. I really have a terrible apartment - it was miracle to get any reception at all in the room. The exterior walls, as it turned out, are covered with metal sheets (wet weather protection), and the window and balcony is facing North, towards Rocky Mountains some dozen miles away. And between those mountains and me there is an electrical Skytrain viaduct, railway terminal at Main Str (I'm at Main and 2nd), plus freight rail-yard, railway engine depot or some engine repair facilities few hundred meters away. Cars and trolley-buses are probably generating more noise than rail yard, though. Btw, I was wrong about Kaito 1103 tuning to AM 1040 when dialing 140 - it is, as I understand, really 140, i.e. Long Wave channel of the same station. |

I am not sure that should respond to something like this at all, but just for the sake of fairness - 7600GR doesn't appear to be superior. Reception and sound are not better than in De/Ka 1103, display is not too good either, no battery charger (I hope there is no need to explain about AC adaptor and SW), and also a bit larger and heavier than 1103 (this is important in my outdoor uses). Somehow Sony have managed to come up with item inferior to 1103, - which is confirmed by slightly lower ratings in all the rviews that I've seen. 7600GR is no longer manufactured, if I'm correct, - and there is nothing newer or better from Sony to replace it. |

Now that I knew where and when to look for, and got rid of AC adapter on SW - using batteries instead, as my friends suggested, and stepped out to the balcony - I think SW works fine for my particular location. Yesterday late evening Radio Australia was more-less where it should. And also RNZI which booms in on a summer evening. The 'blanks' in the ODXA.on.ca World English Survey are usually when they broadcast either their vernacular (Chinese, Swedish, Japanese, etc.) to North America or the Spanish language. Get thee to a Spanish language class in the new year. I really have a terrible apartment - it was miracle to get any reception at all in the room. The exterior walls, as it turned out, are covered with metal sheets (wet weather protection), and the window and balcony is facing North, towards Rocky Mountains some dozen miles away. And between those mountains and me there is an electrical Skytrain viaduct, railway terminal at Main Str (I'm at Main and 2nd), plus freight rail-yard, railway engine depot or some engine repair facilities few hundred meters away. Cars and trolley-buses are probably generating more noise than rail yard, though. The metal isn't that think and you can 'induce' an antenna on your side with a sheet of aluminum foil on the wall and a thin wire off it. Same with foil on the windows or that sticky tape foil window alarm. The metal was another of the infamous Brad Holmes "artist lofts" idea of selling under-furnished apartments for too much money too little fitting, but creating instant 'street-cred' with industrial sheet metal cladding. See the book lists in the back of the ODXA "Listening in" sample issue and think about ordering some. Go to both Com-west on 8171 South Main and also Burnaby Radio (4257 East Hastings) and brows their shelves on antenna books. As a receiver only you don't need thick wire antennas. See from the ODXA.on.ca book lists what your public library has of of the same titles. Burnaby Public used to have a lot of 'ham' and radio books pushed by local entusiasts. You have equal borrowing privileges with them. www.bpl.burnaby.bc.ca/ www.vpl.vancouver.bc.ca/ Those are NOT the Rocky mountains which are 400 kilometres to the east, but the start of the Coast Range of mountains, what the Americans call the Cascades. http://www.bivouac.com/default.asp http://en.wikipedia.org/wiki/Categor...itish_Columbia Mountains don't affect you in the middle of of the Fraser Valley as you are too far away (8 km from a 1000 metre "mountain" and most signals won't come that nothern way (and 1000/8000= is a pretty low mountain unlike Mayo in the Yukon where you don't see the sun), for a signal from the sky to be blocked by them. Besides if you have your azimuth map you can see that sometimes you'll get long path radio from around the world. If you are are at Main and 2nd then you have welding and light machine shops causing arcing as do the trolley buses on wet days. How is it on dry days if you have them, and what about after 6 when many businesses close down? Check the signals when you come home from late-night xmas partying at 4 in the morning. (Europe is having lunch and sending signals to the rising East Coast), but signals don't stop there but arrive after a few attenuating skips to Second and Main. Make a long wire with such things as a PVC pipe or hockey stick Example : http://www.hard-core-dx.com/nordicdx...al/broom3.html http://www.hard-core-dx.com/nordicdx.../northant.html It's not easy to get long continuous wire in town. See what R P Electronic Components Ltd. 2060 Rosser Ave Burnaby has. They have a web site. Learn about loop antennas and their breadth and directionality. And loops don't have to "round" but more like a spider web of spiral wire http://www.hard-core-dx.com/nordicdx...inducloop.html http://www.hard-core-dx.com/nordicdx.../reducin1.html The word "hidden" antenna often means for apartments, e.g. http://www.hard-core-dx.com/nordicdx...den/index.html but have you gotten permission to go on the roof and thead a long wire across its expanse, with a small feed line down? 2 two by fours each stuck in one of those decorative cement breeze blocks for stability and some scarecrow flashes hanging from the wire to keep humans from tripping into it. What area of the balcony can see the southern sky? What neighbour wouldn't mind a stick on one corner of their south-facing (east- or west-) balcony out-of-the-way and a wire to your balcony? And think in three dimensions: a neighbour above, below, to the east to the west. However since you say that you got a good signal from RAustralia, the problem of only being able to see north is moot. Here's a thought about noise sources http://www.hard-core-dx.com/nordicdx...noise_pol.html Btw, I was wrong about Kaito 1103 tuning to AM 1040 when dialing 140 - it is, as I understand, really 140, i.e. Long Wave channel of the same station. There is only a weather long wave. Everything else is a harmonic. Useful but unintentional See the range of Canuck freqencies for Long Wave at Industry Canada Spectrum Search pages by : Geographical Area http://sd.ic.gc.ca/pls/eng_alpha/web...raphical_input More generally Spectrum Direct®: Main Menu URL: http://sd.ic.gc.ca/engdoc/main.jsp#Radio There is an FCC version of the same thing as you have found that you can get 30 Canadian AM stations easily and 100 US stations, being so close to the border. have fun with Xmas loggings You are logging your hits aren't you in UTC-DAY and UTC-Time? -- -\_,-~-\___...__._._._._._._._._._._._.
