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 ?
Best regards,
Hoang
