Dear, Sorry if I have too much question, I am getting started with GNU radio, and I did not find the answer for this on the Internet.
I have USRP1 and inside it has 2 daughter boards: WBX and RFX400. I run the FM receiving grc file and got this UHD Warning: Tune Request: 102.500000 MHz The ification: Target Frequency: 102.500000 MHz Clipped Target Frequency: 380.000000 MHz The RF LO does not support the requested frequency: Requested LO Frequency: 380.000000 MHz RF LO Result: 400.000000 MHz Attempted to use the DSP to reach the requested frequency: Desired DSP Frequency: 20.000000 MHz DSP Result: 20.000000 MHz Successfully tuned to 380.000000 MHz I changed various frequency and figure out the range that has Successfully tuned is from 380Mhz to 520Mhz. I don't know why this happen, the WBX suppose to have range from 50Mhz to 2200Mhz. Does it come from the wrong firmware ? And moreover, my USRP has 2 daughter board, so how can I choose exact daughter board to use ? In UHD USRP source of GNU radio. only have options for antenna port for example RX2 or TX/RX, right ?
