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 |

I'd like (besides the other specifications) some other things (really cool
for european dxers): FM 64-76 extension (for OIRT dx) RDS (really nice to have FM listening) with PI CODE reception 3 IF FM filters frontend (like Satellit 500 or 700 ... cool for FM dxers -) and two kind of FM selectivity (like 280 and 80 khz Murata filters) it could be really cool mp3 recording and two antenna connector one for FM Antenna and SW and another one for MW antenna to disable internal ferrite. internal ferrite could be switch off besides like in Sangean ATS 909 with a stereo minijack) other suggestions made from other dxers are cool too.

LW2,
.. Using the Sony ICF-2010 as a 'standard and a Grundig Satellit 800 M as a Reference: .. * DRM = Digital Radio Mondiale Built-in DRM Signal Processor. .. * Radio Data System {RDS} Information Display .. * AM SYNC with Selectable SSB - Dual Side Band AM-Sync = 6 kHz - Selected USB/LSB Single Side Band AM-Sync = 3.4 kHz .. * Four AM Shortwave IF Band Widths - DRM Extra-Wide 12 kHz - AM Normal 6 kHz {AM Sync} - DXing Narrow 3.4 kHz {AM-Sync Selectable SSB} - SSB 2.4 kHz .. * Two FM IF Band Widths - Stereo/Local FM Normal = 210 kHz Wide - Mono/DX FM Distance = 130 kHz Narrow .. * RF Signal Input Control Three Position : - BOOST = Built-in 10 dB Pre-Amplifier for the Whip and Ferrite Bar Antennas. - DX = Normal - LOCAL = Shortwave Only 2-30 MHz Band Pass Filter with -20dB Attenuation for both the AM/MW Band and FM Band. .. * Large Tuning Knob and Up & Down Tuning Buttons with about 240 to 360 Memories. .. * Dual Tuning Steps: {Fast and Fine} - FM = 200 & 20 kHz - AM = 10 & 1 kHz {AM-BCB = 9/10} - SSB = 1 kHz & 100 Hz .. Separate Antenna Inputs : - FM "F" / PAL Connector - AM/MW and Shortwave - - HI-Z Dual Terminals {A&G} - - LO-Z Jack SO-239 .. * Speakers Three (2:1) for FM Stereo - One Rear Facing Bass {4.5" Sub-Woofer} - Two = Left and Right Front {3" Stereo} - Audio Output Selector Switch: - - Mono Talk & News {Voice} Front Two - - Mono Music all three speakers - - FM Stereo - HiFi (2:1) NOTE - Sort of like the Grundig Satellit 2400 Dual Speakers put the Controls in the Center and the Speakers on the the Left and Right Front Sides. http://www.dr-boesch.ch/radio/grundig-sat2400.htm .. * Built-in "D" Size Rechargable Batteries with an 'external' ACDC Power Adapter / Battery Charger. Auto/Car DCDC Power Adapter / Battery Charger. .. * The Right "Size" - About the Size of a Panasonic RF-2600 'portable' AM/FM Shortwave Radio : NOTE - Look at the Lay out of the Controls and the Big Main Tuning Knob. http://www.dxing.com/rx/rf799.htm - 13.5" W - 9.3" H - 4.6" D - Seven Pounds (7 Lbs.) .. well thats my double-nickels worth ~ RHF |

the 1103 and 800 are from competing companies are you sure this is on
the level ? |

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. |

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 ? |

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 ? .. i want to know ~ RHF Actually Degen used to be a subsidiary of Tecsun several years ago, the main business is radio sales, aftermarket service and Electrical Design, no production line, some Tecsun's radio electrical designing was come from Degen, but now Degen was completely separated and independent, Degen has full capacity on receiver designing, mass production and has own sales channel, Degen become a powerful competitor of Tesun thus far , sure some Tecsun's shareholder has shares of Degen, but it absolutely not affect the competitive situation. once tecsun bring out a new model, then Degen has a similar one to compete, for example: Tecsun 9700DX~Degen 1107, Tecsun PL550~Degen 1103, Tecsun PL350~ Degen 1105, Tecsun PL200~ Degen 1102, now Degen are building the flagship of DE110* series , we would like to see what does the Tecsun bring to desk |
