Steve,
He won't or can't answer your question. Every Chinese company has "connections" with the Communist Party: In this link are some interesting comments from a corrupt CCP businessman: http://english.epochtimes.com/news/5-1-28/26080.html "dxAce" wrote in message ... wrote: More to the point, what does your question have to do with Degen radios and shortwave listening. [?] It was a legitimate question regarding DEGEN radios. (And other Chinese sets as well) You may not like being reminded that by your purchase you help fund the PLA and help promote slave labour? Got a problem with that, 'tard boy? dxAce Michigan USA I am impressed that the designer of the DE1103 has given us some insight into that radio and more importantly has asked the SWL community for suggestions on how to design a new radio. That is a first for me. I think we should focus this discussion on Degen and their shortwave radios. And I'm sure you agree. dxAce wrote: Joe Analssandrini wrote: Dear Sir, At the risk of posting too much, may I say that I understand that Degen is one of China's leading radio manufacturers. As such, I hope that the design of this radio is a "no-holds-barred" short wave receiver of absolute top quality. Ergonomics especially should be user-friendly. Menu-driven radios are perfectly acceptable IF the owner's manual is comprehensive and complete. (I own an AOR AR7030 Plus, the best performing radio I have ever owned, which I find very easy to use due in part to its superb owner's manual. Though menu-driven, its ergonomics are superb.) NO "FRILLS" (such as a "fake" analog dial) should be on this radio; everything incorporated should be there for a distinct purpose: the best possible reception of the signals desired. I sincerely hope you will take into consideration my suggestion to incorporate the various new terrestrial digital reception modes. It is not necessary (nor, in my opinion, desirable) to incorporate XM or Sirius satellite "pay" reception into this forthcoming radio. Satellite radio can better be served by another separate receiver. As I stated above, ABSOLUTE TOP QUALITY in DESIGN, COMPONENTS, and CONSTRUCTION QUALITY are of PARAMOUNT importance. Degen should market this radio in the USA under its own name. If the radio is a great one, this will give impetus to awareness of the Degen name in the United States. I believe that, if any company can design and market a near-perfect short wave radio, Degen is that company. My question is: What relationship does DEGEN have to the PLA (People's Liberation Army)? dxAce Michigan USA |

Hello,
The radio should offer: Dual or triple conversion with no less than excellent front-end selectivity. Full coverage from at least 100 kHz to 30000 kHz AM (no gaps), 76-108 MHz FM, and possibly simple air band reception (118-137 Mhz). 4 or 6 rechargeable-NiMH "D"-cell operation with MANUAL switch on back to choose AC or Battery operation (so that AC Adapter need not be unplugged when on battery power). Synchronous-selectable sideband reception is a MUST. Should be designed at least as well as that on the Grundig Satellit 800. Full passband tuning would be even better. Lock must be held as well as on AR7030 model and must automatically turn off when tuning and then re-lock when station is selected. A good notch filter (with at least 50 dB depth) with range of 0.1 - 5 kHz. At least 3 IF filters (bandwidths) (preferably 4) of 2.2 kHz, 4 kHz, 6 kHz (and possibly 1 kHz for data/CW); operation of these filters should be cascaded so that inexpensive ceramic filters will give much better performance than usual. (6 filter bandwidths would be ideal.) All shape factors should be less than 1:2. All parameters should be fully adjustable independently in all modes of reception (except FM and the digital modes). At least 200 memories. Tuning via knob (no "chugging" or muting), "slew" buttons (5 kHz on SW, 9/10 kHz on MW, 9 kHz on LW, and 100 Mhz on FM). Signal-scan automatic tuning. Memory scanning. Automatic memory sorting. Automatic station setup (as on Sangean models) for AM and FM memories. Remote control operation possible with a CORDED detachable remote control (at least 6 feet in length or adaptable to an extension cord if user desires). Dial illumination via LEDs, perhaps color-switchable (Red, Blue, Green). Dial light scheme similar to Grundig Satellit 800. (Always on or always off with AC power, on for 15 seconds with any button push when using battery power, or always off with batteries, as desired by user.) Line outputs for external speaker(s) and stereo system. Excellent sound quality is a must. Independent tone controls (Treble and Bass) should be incorporated. Internal mono speaker of high quality is preferable to mediocre stereo speakers. At least two external antenna inputs for AM/SW (high and low impedence) as well as an FM antenna input. Built-in antennas should be: a LONG (possibly detachable) whip (PLUS a shorter whip possibly optionally offered for travel); a LONG (at least 130 mm) internal ferrite antenna for MW and LW. External antennas to override internal ones. IBOC reception (AM & FM) for the US. Canadian DAB. (Possibly European DAB.) Self-contained DRM (or a 12 kHz IF output to connect to a DRM-equipped computer). Clocks should be RADIO-CONTROLLED (and operated independently from radio and powered via 2 AA or AAA batteries). Two times zones should be available, one of which should be UTC. Local time should be adjustable for daylight-savings time (via radio control) if required; UTC should NOT be affected by DST change. One of the clocks (including seconds) should ALWAYS be visible, radio on or off. No LEDs (except for dial illumination and possibly button illumination). Properly calibrated digital bar graph S-meter of at least 12 segments. A high-quality plastic cabinet or, preferably, a light-weight metal (aluminum or magnesium) cabinet. ALL internal components to be of TOP-QUALITY (formerly known as MIL-spec). Excellent sensitivity; a 3 or 4 step attenuator (or adjustable RF-gain control) should be incorporated. All other specifications to be of Drake R8B/AOR AR7030 caliber, especially blocking, ultimate rejection, image rejection, and, most important, dynamic range. Excellent sensitivity (a 3 or 4 step attenuator would be of help). A carrying case (nylon or leather) should be optionally offered; this should be able to carry AC adapter, batteries, and any other options, as well as fully protecting the radio. Servicing is important. All service information should be made available on line. Guy Atkins has made some important suggestions; his suggestions should be incorporated also. A tall order? Yes. A "perfect" radio? Almost. There has never been anything like it! What should this radio sell for? I would pay $1000 or more for such a radio; could it be manufactured in China for $700? Since this is to be your top-of-the-line radio, it should be designed and made as perfectly as possible. You make it, I'll buy it! Joe |

sure the chief engineer of SAT800 is from Tecsun ,one of the biggest
radio manufacturer in China, now he has left the job then running a independent design house, the DE1103 if one of his design out for DEGEN company. |

Dear Sir,
I should also like to add one more item to my list posted previously: all memories and the firmware should be non-volatile. Should battery and AC power be disconnected, all information should be retained permanently (until changed by the user). All my best wishes for the success of this forthcoming receiver. Joe |

LW2,
.. Some where i thought that I had read that Tecsun GEM China (PRC) 'owned' or was a major share holder in Degen. ? Now Is That True ? |
