XHDATA D-808 FM-DXing Comparison with the Tecsun PL-380  View Printable Version 
Saturday, June 02 2018

IRCA
Paul,


I've ordered (and received) two of the D-808 models from the following eBay listing https://www.ebay.com/itm/XHDATA-D-808-Portable-Digital-Radio-FM-stereo-SW-MW-LW-SSB-RDS-Air-Band-LCD/263589135532?hash=item3d5f2304ac:g:gzgAAOSwCBFaxd8G
The delay time in receiving the model was about 4 weeks, so it isn't a quick process. Somehow the seller got away with shipping me two of the type 18650 3.7v Lithium-Ion batteries through the mail, although USPS regulations supposedly forbid this. Who am I to complain?
The batteries can also be purchased via eBay, if he won't continue including them, and you can't find them locally.

XHDATA D-808 FM-DXing Comparison with Tecsun PL-380  View Printable Version 
Saturday, June 02 2018

IRCA
After receiving an inquiry from Mark Roberts concerning the new XHDATA D-808's FM-DXing sensitivity, I decided to run a detailed comparison with the Tecsun PL-380-- one of the Si4734 DSP chip models which gained top FM-DXing honors in the 2015 Ultralight Radio Shootout review. In my very mediocre Puyallup Valley location (surrounded by hills on 3 sides), I checked three FM fringe stations which have a reputation for being tough FM catches


The new XHDATA is a very sensitive performer on the FM band. In direct comparison with the PL-380 in outperformed the Tecsun in the reception of the low-powered 95.3 KGY in Olympia, WA, 100.3 CKQQ in Langley, BC, and 106.5 KWPZ in Lynden, WA. The D-808 had 95.3 KGY at a weak level, while the PL-380 had nothing at all. On 100.3 the D-808 had CKQQ at a good level (plus an UnID Spanish station under it) while the PL-380 had only CKQQ at a fair level. On 106.5 the D-808 had KWPZ at a good level, while the Tecsun had it at a fair level. FM selectivity was identical in the two models. The D-808 benefits greatly from its 26" (66cm) whip antenna, compared to the PL-380's 21.75" (55cm) antenna. In addition the D-808's RDS capability really augments the model's FM-DXing sensitivity, adding an extra dimension to the entire experience. FM-DXers can order with confidence!

Where can you buy one? The sites I've checked won't ship it to the US
(not FCC-approved, maybe?).

TP 31 May Victoria version  View Printable Version 
Friday, June 01 2018

IRCA
Initially, this morning seemed like a complete wipe-out. However, a couple of DUs did make a fleeting appearance.


pretty darn good audio (all of it understandable by a native speaker, at least briefly):

not today

Reasonable audio at times during the period (much of it understandable by a native speaker, though often battling w/splash or noise):


no


not so reasonable audio, occasional words or phrases in splash or noise could be understood by a native speaker:

and no


Burbles in the splatter and noise (if lucky, language might be guessed at by cadence of talk, or parallel established by changes in talk or music)

612 4QR ABC fanfare 1200UT; Murphy was napping, as that was its peak strength

702 2BL 6 pips but most of fanfare concealed by splatter, 1200UT


Strongish het, no or "near imaginary" audio (either undermodulated or ravaged by splatter)

nothing seemed to be Asian;
567 774 1017 seemed to be DU

best wishes,

Nick
