Hi

I’m new to the GNURadio, so I’m trying to get some of the
basic tests. I am using Flex 2400 daughterboard

This is important later on …

I’ve run the dial_tone.py example, and it is running. for usrp, I have
tested usrp_wfm_rcv.py. I’ve connected daughterboard to RXB and TXB.
Then I write ./usrp_wfm_rcv.py -f 96.5M, I get an error message as follows
1. FYI: No powermate or Contour Knob
2. Failed to set initial frequency (on USRP WFM RX screen)
3. (python 6931): GnomePrintCupsPlugin-WARNING **: The CPUS
printer couldnt be created

… as it seems you’re trying to tune a Flex 2400 to 96.5MHz.

You need to either:

  • Tune to a frequency the Flex 2400 can tune
  • Acquire a board that can tune to the frequency of interest (96.5MHz)

[W]hen I test usrp_wfm_rcv.py -f
2400M there is no error message ‘failed to set initial frequency’ but
other warnings are still there:

  1. FYI: No powermate or Contour Knob

This is just an information. If you have one of the two mentioned input
devices, you can use them to control the interface, e.g. set the
frequency, volume etc.

  1. (python 6931): GnomePrintCupsPlugin-WARNING **: The CPUS printer
    couldnt be created

A known message from GNOME.
You should not worry, you can ignore both.

In the range of the RFX2440 you won’t find any FM radio, so you will
just get static noise. Not very interesting.
Use a BasicRX or a TVRX for FM Radio, these support 88-108MHz.
