I placed a table in my driveway, far away from any source of RFI, and set up the radios in identical configurations: same orientation, antennas fully-extended, same AM bandwidth (4.0 kHz), same audio levels, etc. For good measure, I also included the venerable Tecsun PL-660 in the mix.
This was still daytime listening, so all of the stations were from 31 meters and up.
Apologies in advance: somehow the cord from my monitoring headphones is in the shot on some of these videos! I’m still getting used to the new Zoom Q2n video camera:
WRMI 9,455 kHz
WWV 15 MHz
Deutsche Welle 15,200 kHz
Afia Darfur 9,825 kHz
I should add that QSB was slow and deep on Friday. Twice I had to re-shoot videos because the station simply faded into oblivion.
I plan to do a few more comparisons with the XHDATA D-808 and Digitech AR-1780 soon as I’m very curious how SSB reception may differ.
Please comment with your observations. Which radio did you prefer? I’ll hold my comments for now.
