Hi, I received my dvb-t dongle this morning (order number PI178461), thanks. Problem is it doesn’t work for ADS-B. The dongle is recognised OK, the led is lit, When going through the instructions listed for dump1090 (the software recommended on the dongle’s web page) it passes all the tests. It can pick up (using kalibrate) some of the lower frequencies on the GSM900 bands and it picks up a couple on the GSM1800 and GSM1900 bands so I know the receiver is working OK.
The error shown is:
[FC0012] no valis PLL combination found for 1090000000 Hz!
The problem seems to be the onboard tuner in the device, this is shown as being a “Fitipower FC0012” which unfortunately has a gap in the receive frequencies between 948.6 Mhz and approximately 1400Mhz. The frequency needed for ADS-B is 1090 Mhz - right in the gap!
Google “Fitipower FC0012” for plenty of results which give the specs of this tuner.
Bottom line is, this dongle is simply incapable of receiving the required frequency for ADS-B.
