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
About this deal
Intermodulation products seem to show up most prominently around 7MHz, 10MHz and in the 15m ham band first. This difference is partly due to the fact that the D-808 seems to be a tad more noisy and partly owed to the better speaker of the PL-660.
I purchased a second receiver because I did believe that the receiver was highly sensitive and highly capable and would be worth the money if I got one that didn’t have the high pitched squeal. The better your problem and question is described, the easier it is for other Xhdata owners to provide you with a good answer.Additionally, we always try to include links to other retail options if they are available, as we support and freely advertise independent ham radio retailers. I tried to install the 18650 protected cell that came with my Tecsun PL-990 and its length and width caused my Sihuadon D-808’s contact spring to bend.
The front panel board is near-identical; the front end / RF board uses lightly different transformers, different style of variable caps associated with each, and apart from that the only real difference I’m seeing is a slightly different layout around the power connector and the generally poorer assembly quality of the Digitech. The chuffing sounds different and the background noise sounds wider with more hiss, then after a while (this can take several seconds) the filter pops back in with the regular puff from the AGC.

Without getting into the political ramifications of such behavior the obvious fact in the 2021 portable radio market is that all of the top competitors in this Shootout come from factories in China, and four of the five have Chinese name brands. Secondly, this one is even more deaf on LW than the old one, it’s picking up sensitivity 100kHz higher around 400kHz, so the NDB band is deaf on this one too. Many thanks to SWLing Post contributor, Gary DeBock, who shares his extensive 2021 Ultralight Radio Shootout.Predecessor of famous XHDATA, with exactly same functions and muting, but with even better sound, better construction quality, sturdier, smaller and powered with AA batteries. I am new to the hobby and would like to know if the D-808 alphanumeric display is used for anything other than RDS. Here was a small, well-designed DSP radio that burst upon the scene with outstanding capabilities and which even today is prized among those who own it.
