Thank you, Matt. Is there any other way to transmit in the frequency
range of 70M - 84M Hz?

When I tried to set the center frequency to 80M using Basic Tx
board, the error message I got is as follows. I also tried some
other frequency, from 70M - 84M , and had the same error. For
most of the other frequency, it works fine. $ ./usrp_siggen.py
--const -i 32 -f 80M usb_control_msg failed:
usb_control_msg(DeviceRequestTO): pipe is stalled Using TX
d'board A: Basic Tx Failed to set RF frequency Does anyone know
the reason for this and how to solve this? Thank you very much.
The DAC sample rate is 128 MS/s, and due to the sinc shape of DACs
it means there would be very low signal around nyquist (64 MHz) and
its multiples. So we don't let you set those frequencies as you
wouldn't get much signal anyway.
