Re: [Openlte-discuss] Testing LTE_fdd_dl_scan with a rtlsdr dongle.

[Ben W. <bwo...@gm...>]

There are center frequency limits when using the rtlsdr dongles and it
appears the earfcns that you are trying to scan are beyond that limit.  Can
you try using a band that is lower in frequency?

Thanks,
Ben
