3 years ago What are you using to receive the output signal? Consider using SDRangle or GNURadio. Have you used bladeRF-cli to transmit a CW and measure its output frequency? If you input a CW into the bladeRF, and look at it using sdrangel, does it appear in the correct location? A frequency error would be present in both RX and TX, and would likely scale with the center frequency, could this just potentially be a measurement error? Please consider the CW tests mentioned above.

hello, I am a new and proud owner of blade of bladerf 2.0 xa4, a few days ago, I did a signal transmission test with bladerf at the frequency of 435.0mhz, the receiving device sees at least 437.0mhz, sometimes even 437.5mhz, I have tried to transmit with bladerf at 1800.mhz, but I receive minimum 1802.0mhz 1802.7mhz, I tried with different software, gqrx,yatebts,sdrangel that transmit signal but always the same error of minimum difference 2.0mhz up to 2.7mhz. How can I correct this problem? thanks and sorry for the english
