|Creative Design New FM+DAB USB DVB-T RTL2832U+R820T|
|EZCAP eztv645 RTL2832U / FC0013 USB DVB-T Digital TV Dongle|
Both arrived yesterday. I tried the ezcap first, but my shack PC didn't like the mini-disc that came with it so I was unable to test it as a TV receiver. Following the instructions for the aircraft decoders I installed the driver using zadig_xp, then downloaded and ran rtl1090 which is a decoder for the ADSB packets. This seemed to work - no error messages appeared - but nothing else happened. To display the aircraft data that I hoped to receive I downloaded ADSBScope and installed it. I then spent a lot of time trying various options to connect ADSBScope with rtl1090 but got nowhere. I also tried SDRSharp in the hope that I could use the dongle as a VHF/UHF SDR, and ADSBSharp as an alterntive to rtl1090. But neither of them received anything.
After a while I gave up, disappointed. I then installed the Creative Design dongle and its software. A scan for channels found about 55 TV channels with its quarter wave antenna hung in the window. So it was obviously working. Just not with any of the SDR or ADSB software, as I had suspected.
This morning I tried installing the ezcap software CD that my shack PC couldn't read on another computer. The software installed perfectly on this laptop so I plugged in the dongle and hung the antenna in the window. The software scanned for channels and found precisely nothing. I think this proves conclusively that I have a duff ezcap dongle. Ah, eBay!
