In this particular case, it's actually not very important. Kal is basically performing a tone search and the sample rate used for internal calculations is the rate returned by UHD. The sample rate can be almost any value. 2 kHz offset is within tolerance for 1900 MHz. Locking to a stable 10 MHz reference, generally an OCXO or GPSDO, is the recommended approach. -TT _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
