Re: [Discuss-gnuradio] u2->set_tx_center_freq(freq, &tr) setting failing.

[Hanno Jung]

Hi,

if you're trying to tune to 1100 Hz this should be too low for an rfx 1800.

With that daughterboard try somethinf around 1800 whithout commas.
I don't know if this format is supported.

Daughter Board:  RFX 1800
what is the range i should have to provide? I tried orbritarily 1,100 (Internally what value it takes, ex: 1 means 1GHz or 1 means 1Hz).

best regards,
srinvias.

Hi,

The Tx center frequency setting failing in the gnuradio-3.2.2 stable
release, when i try on my USRP2 to
transmit samples onto other USRP2 box. Even without specifying the
-f freq option also failing at this for
setting the default value setting. Could some body help me out, any
fix i need to take, if it was not in the
3.2.2 release.

=============gnuradio-3.2.2/usrp2/host/apps/tx_samples.cc=====================
 if (!u2->set_tx_center_freq(freq, &tr)){
  fprintf(stderr, "set_tx_center_freq(%g) failed\n", freq);
  return 1;
 }
==============================================================================


best regards,
srinivas.
   

What daughterboard are you using?
What is the value of freq?

Eric
