Скачать или смотреть XHDATA D-808 vs Deepelec DP-666 - which is better on shortwave?

In my opinion, XHDATA D-808 has a bit lower noise on SW while Deepelec DP-666 is a bit noisy on AM bands even when the display is off.
TEF6686 has better sensitivity on FM band but it is also excellent on LW and MW bands - none of my radios (except the Pioneer MVH-S120UBA) can receive PR1 Jedynka on 225 kHz during the day, in summer!
In addition, TEF6686 chip is always a good choice for car radios! (my Pioneer car radio has it)

Bandwidth on both radios is set to 6 kHz, antennas are aligned in length :)

What about the AIR band on Deepelec DP-666, when it has received China Radio International there, I thought to myself: "What the ____ ! It receives spurious frequencies from SW!"
XHDATA D-808 has separate chip for AIR band while Deepelec DP-666 has TEF6686 that does everything by itself! 😲

P.S: As mentioned previously, both these radios are GOOD! :)
