Subject: [UltralightDX] Old Version D-808 Vs. New Version D-808-- Weak Signal AM-DX ShootoutIn what is probably the first "shootout" in which old and new versions of the same model compete against themselves, this comparison was made after China's XHDATA company completely revised the RF boards in their D-808 model without any notice, resulting in slightly poorer reception of weak AM-DX stations. As far as I can tell, this major revision was made in late 2022, and the sure-fire way to identify a "new version" D-808 is by the USB-C connector on the model's right side (as opposed to micro-USB connectors on all original D-808 models).
An old-version D-808 (S/N D8082017120587) was matched up against a new version D-808 (S/N D80822L6241) in stable daytime DX conditions around local noon in my noise-free back yard. Only very weak AM-DX stations were used for this test, so the volume controls on both models were maxed out. In each fringe station recording the original model D-808 receives the weak station for the first 15 seconds, followed by the new model D-808 for the final 15 seconds. Both models were set up in the 1 kHz DSP setting (which provides maximum sensitivity), and both models were directed for best reception of the fringe station.

Czy można zaufać sprzedawcy (producentowi?), który taką amatorkę odstawia?
To wygląda jak tani scam.
Niewielkie różnice w porównaniu do Tecsuna pl-330. W internecie jest sporo porównań.
