Re: PLL not locked

Do not type the "-t". Just type "rtl_test"

I get the same error when I tried "rtl_test -t". My dongle uses the R820T tuner, as does yours. It looks like the "-t" is something for a dongle with a E4000 tuner. I've never used any of the command line options on the rtl_test command.

Re: using xtal other than 28.8 MHz

Thanks for the link. I didn't measure the phase noise, I just looked at the spectrum on an analyzer, and it was lousy. When I use this TCXO with the dongle, if I put in an offset carrier I see quadrature sine waves on I and Q, but they are swamped with noise. It isn't pretty. At first I thought I mi...

using xtal other than 28.8 MHz

I would like to use a 26 MHz TXCO with the RTL-SDR. I see where the software allows selection of a different tuner XTAL, but when I try using a frequency much different than 28.8 MHz, the USB does not register. I drove the clock input with a function generator, and it works with 28.8 MHz, but deviat...
