[Discuss-gnuradio] Failed to set TX frequency!!
Hi, I think there is a problem in setting TX frequency of Basic daughter board using the USRP tune function in the range from (45MHz to 83MHz)!. Outside this range, the tune function is working fine.

What is happening that shouldn't be happening? What isn't happening that should be happening? What do you see on your screen? Has it worked before but something changed and now it is not working?

Re: [Discuss-gnuradio] Failed to set TX frequency!!
Hi Johnathan, Sorry for not being clear. I was making a new usrp_source.py usrp_sink.py files (attached below) to be posted to gunradio. Testing the new usrp_source.py code was ok for all frequencies and daughter boards. However, testing usrp_sink.py code, with TX frequencies between 44MHz and 83 MHz gave me the tuning function failing indication which I use it to print the message Failed to set TX frequency. This is strangely happening to the Basic TX daughter board only in this frequency range.

This is strangely happening to the Basic TX daughter board only in this frequency range. The digital upconverters in the AD9862 don't allow you to set the frequency to values close to the nyquist frequencies. Since it samples at 128 MHz, the prohibited ranges are around multiples of 64 MHz.
