XHDATA D-808 Portable Digital Radio FM stereo/SW/MW/LW SSB RDS Air Band Multi Band Radio Speaker with LCD Display Alarm Clock External Antenna

Product Information

You will likely get significantly better range by using some ism band dedicated transceiver chip (like cc1101 from TI) than kludging a FM broadcast band transceiver to do it. A valid product review is one where you have experience or knowledge of the product that you would like to share with others. The supplied 3.7v lithium ion battery has superior run time, and may be easily charged using the supplied USB cable to either a computer or AC outlet (with the appropriate adapter). As reported in various posts throughout this year, the D-808 model has rugged construction with an excellent record of survival under tough conditions, including hot summer days, moderate rain exposure and extended usage as the main receiver during a 9-day ocean cliff DXpedition in Oregon—performing flawlessly at all times. Conclusion Na dlouhé anténě (cca 25 metrů) se XH DATA během dne chová dobře. Vnočních hodinách má sklony se zahltit, což není nic překvapivého. The D-808 is shipped with a non protected button top 18650 battery with a 67mm length. The protected kind averages 69mm in length and have a conducting strip for the protection circuit board attached at the negative pole.

The first option is the temperature in either Centigrade or Fahrenheit (depending on your pre-set preference), while the second option is the alarm time. The third option is the current time (which you need to set according whether you prefer UTC or local time), while the fourth option is the received signal strength in both dBu and dB. Absolutely amazing! Thank you for taking the time to put this procedure together and describing the process in such fine detail, Gary! Hats off to you! I remember about 20 years ago, I was on the mailing list for one IC company and there was a string of intriguing cellphone ICs. Wait, it was Maxim, and they offered samples. I kept looking at those, knowing they had a lot of what was needed for “SDR’, but it was never clear from the bits they sent out whether they were too sculpted to cellphone applications or they could be shifted to “useful” frequencies. Pod displejem se tradičně nachází klávesnice. Má velmi malý zdvih, avšak je spolehlivá. Pokud jste zvyklí na poslech v posteli, kdy vedle dřímá drahá polovička, jemné cvakání kláves ji rozhodně rušit nebude. The first time we drove up the road to the lighthouse on the Mull of Kintyre we stopped and I put out a call with the modified walkie talkie and got 57 from the west coast of Northern Ireland about 70 miles away.

You can add to or update/edit your existing review's content including the Rating and Time Owned with the Edit button on the right side of the review text body. Edits will go thru the review Approval process. Obviously if Silicon Labs do not allow user programmability of the chip that is off the agenda at least for now. If your new review has not been Approved after several days you can assume that it was found to not be within the product review T's&C's shown below during screening.More Info: https://xhdata.com.cn/collections/xhdata-hot-selling/products/d-808-radio?variant=43660713558334 The Si4735 DSP chip has markings of “3560, DCUL, .738” and provides a wide range of AM bandwidth choices for the Medium Wave DXer (6K, 4K, 3K, 2.5K, 2K, 1.8K and 1K). These perform very well, and as with the other DSP-enhanced portables, the narrowest bandwidth (1K) provides the most sensitive AM band reception. When your Litz wire lead ends resemble the photo above, cut the soldered portion down to a length of 3/16” (5mm) and observe the appearance of the end of the Litz wire. It should have a bright, solid circular shape, with no gaps or individual Litz wires showing. If not, reheat the end of the Litz wire while adding some solder, and repeat this step.

Radio Waves: SWL Contest, Shortwave Modernization Concerns, Still Need AM, and ARRL Asks for Comments on 60M Rulemaking Refer to the photo below. Using the flat Jeweler’s screwdriver, once all of the glue bonds have been broken and the ferrite rod is loose in its slot, lift the ferrite rod out of its slot on one side by prying up under the plastic cover on the end of the ferrite rod. Ensure that the Litz wire leads have either been cut or desoldered from the circuit board, then grasp the ferrite rod with your fingers and pull it completely out of the slot with a slight twisting motion. The silabs chips can do SSB demodulation, but they seem to have contracts in place as they seem to exclusively supply those to tecsun and other portable radio manufacturers, but not the general public. Přijímač XH DATA je pocitově velmi dobrý výrobek. Pokud vezmete na milost jeho strohý design, bude se vám líbit. Rádio skvěle padne do ruky. Je menší než recenzovaný Tecsun PL-660, což rozhodně není na závadu, spíš naopak. XH DATA bychom se nebáli nazvat kapesním rádiem.Na krátkých vlnách je XH DATA jako doma v celém pásmu, tedy 1,7 – 30 MHz. Umožňuje poslech AM, LSB i USB, a to velmi slušně. Máte dokonce možnost si aktivovat filtry od 500 Hz výše, které jsou pro poslech skutečně užitečné. I) Amidon 7.5” x .5” ferrite rod, part no. R61-050-750 (MW model) OR part no. R33-050-750 (LW Model), available at http://www.amidoncorp.com/rods-and-tiles/ Se světovými přijímači se vposledních letech roztrhl pytel. Dříve to byl zejména všeobecně známý Sangean, následovaný vtěsném závěsu SONY, Grundigem a Etonem, dnes vládne ryzí „čína.“ Nesmíme zapomenout ani na „naši“ Olympii ATS-803, na které mnoho znás začínalo. XH DATA D-808 je velmi slušné rádio, které připraví svému majiteli mnoho radosti. Pokud používáte paměti, připravte se na poněkud krkolomnější ukládání.
