DEGEN DE1108 worldband receiver is now in preliminary design stage, any one has recommends on it?
wrote in message ups.com... The designer(also the main engineer of DE1103 & Grundig SAT800) now ask advise of the receiver function from BCLer, the DE1108 will be the high-end receiver of DE 110X series, it comes with a large dot matrix LCD display(128*64) two way speaker system, MP3 recorder, AM sync detector, SSB, dual conversion, the reference basis is SAT700, it should has better performance than sony 2001D, 7600G, SW77 even SAT700, the outline dimensions will be large than SAT700,pls post your thougts here, I will take the message to the design, thank you! OK, here are a few thoughts on features I would like to see on the DE1108 portable: 1. Digital readout to a finer resolution than the Sony 2001D. A readout of 0.01 kHz would be very nice. 2. A passband tuning control (PBT) such as the Eton E1/Grundig Sat900 will have, useful to at least +/- 2 kHz range. If passband tuning cannot be included, then the AM synch detector should be a SELECTABLE SIDEBAND type, as with the Sony's. Ideally, the new Degen would have both of these features. 3. Sensitivity at least as good as the DE1103, which is a useful portable here on the West Coast of the USA where signals are weaker. 4. A comfortable, large tuning knob, without audio "chuffing" (muting) when tuning. The tuning knob on the DE1103 was a step in the right direction, except it couldn't be very big due to the small size of the radio itself. Guy Atkins Puyallup, WA USA |

One idea would be to make it a "hang on the wall" shortwave. Desk space is problem for a lot of us, and I think a radio with a form factor like a flat panel TV would be neat. (My 2 cents worth. $.02 is probably asking too much). Mark Zenier Washington State resident |
One thing I have long waited for -- a radio with USB flash drive support.
It would be great to record off the radio with different quality bit rates (low to high) and transfer the files to my pc for CD archiving or vise versa for playback on the radio. wrote in message ups.com...

Also, a bright orange or green (or white) backlight is preferable to a DIM
blue one, even if blue LED's are more trendy. |
Any Degen product priced under 100 Yuan would be just perfect.

HI all,
I have a Degen 1103. It's a good rx. About the 1108 I suggest to care about FM section. In the world there are a lot of Dxer looking for a good FM radio since Grundig Satellit 500 and 700 disappeared. Here are some important features about FM section, with low cost to implement it: 1) coverage also of East Europe OIRT FM 65.9 - 74 MHz 2) 3 IF filter (bandwidth, with low price Murata ceramic filters): narrow 53 kHz for hard dx; middle 110 kHz filters for better RDS decoding also in dx; large 180 kHz filter for music 3) 10 kHz step possible 4) External antenna possible for FM too 5) RDS with also PI code reading as Sat 700 6) Connection with a computer for RDS decoding and analysis, via serial port (better) or jack Features 1 - 4 - 5 and also 6 can be obtained without too many problems also with Sangean 909. The feature #2 is obtained on Sangean (only one fix bandwith) changing the 10.7 IF filters with a Murata ceramic one. 73 Giampiero wrote in message oups.com...

First my idea about the MP3 recorder:
-96-112 kbps for FM Stereo -max 20 kbps for AM It can be useful if common flash (removable) memories will be used What about adding VHFII band?

First my idea about the MP3 recorder: -96-112 kbps for FM Stereo 112 max seems a bit tight to me. Even with frequencies up to 15 kHz only, the maximum should be the equivalent of ~200 kbps ABR/VBR from a CD (around 160 or so?). Noone has to use that, but the recording from a high-quality station at maximum quality should be indistiguishable from the original even using good headphones. -max 20 kbps for AM A selection of 16, 24 and 32 kbps seems reasonable. It can be useful if common flash (removable) memories will be used Yup. Since size is not an issue, I'd look at CF. Stuff in a big Microdrive or similar and record forever and a day, plus potential incompatibilities are minimal since CF cards have their own controllers. What about adding VHFII band? ( 150 -180 MHZ ) Hmm, what's that used for? It would most likely require a separate frontend since you can't expand FM band coverage indefinitely.

Using blue is just inefficient considering us ordinary humans have the maximum sensitivity in the yellow-green range.

While any open sourced digital recording ability would be GREAT, I'd
prefer mpeg4 or AAC format for its better quality in a smaller file. However, as a beggar, I won't be a chooser! I'm already putting a few bucks away a week for this radio when it is rolled out. I love my Degen 1102 and would have no qualms about buying another product of theirs. Zach Liang wrote: First my idea about the MP3 recorder: -96-112 kbps for FM Stereo -max 20 kbps for AM |

Yes, and I'll jump in with a third. The DE1103 is also proof that
Kaito can design good performing inexpensive radios. If they go up-market they will have to consider receiver performance as well as the numerous features we all want. Dynamic range, selectivity and image control become a whole lot more important in the over $500.00 price range that the DE1108 will probably price out at. |
Nawwww,I am saving up for a Sony 7600GR Radio.
