This is a parallel recording of the same transmission from Shannon Radio on 13,264 kHz USB. In other words it's the exact same transmission both radios receive, and I only play them consecutively so you can hear the difference. The first radio is probably one of the radios hit worst by the Si474x chip's AGC quirks (this is reportedly a bit better on the more recent radios with that chip) - the other one is the 2022 Belka v3 set to not pull up the noise so much.
Just putting that here so you can draw your own conclusions out of it, given the original asking price of IIRC $160 w/o shipping & taxes not being a whole world apart from all the other SSB portable offers. Listen to it a few times and imagine you want to listen to both radios for 3 hours.
(If you think the second audio clip was turned up louder - it's actually peaking 0.2dB
lower than the D-808-clip. It's just the XHDATA's AGC letting the attack transients pass, causing hefty peaks in the radio's audio stages and the AGC pulling back the gain late and far too much then lowers the overall loudness.)
