Hey all,So, our inband code transmits and receives just fine using the basic TX/RX boards at 10MHz. We want to run it using the FLEX2400 daughtercards at 2.4GHz.
Using usrp_siggen.py and the oscope, we can generate a sine at 2.4GHz and watch it.
I believe the center frequency is hardcoded right now in the USRP interface m-block:
http://gnuradio.org/trac/browser/gnuradio/branches/developers/gnychis/inband/usrp/host/lib/inband/usrp_usb_interface.cc#L278 That's where we set the center frequency of channel 0 to 10MHz.When I switch this to 24e8, set_tx_freq returns an error while using a 2.4GHz daughtercard. It does *not* return an error setting the center freq to 10MHz while using the 2.4GHz daughtercards... so I'm confused.
Thanks :) - George
