Last week I have tested the RTL2832U-based ezcap EzTV666 DVB-T dongle on the air using various VHF signal. Already Saturday I attempted to receive APT from the NOAA-18 weather satellite. These satellites are always very strong and it was no different using the EzTV666 as you can see on the screenshot below. I was using a handheld ArrowII antenna using an extra adaptor cable, but nothing to match the 50 Ω from the antenna with the 75 Ω in the dongle.” — Alexandru Csete
