I’m new in gnu radio and am trying to implement a prototype of new radio
based on USRP platform. We’re receiving several waveforms in different
frequency bands and we want to incorporate a special functionality, just
a demo: The idea is receiving broadcast AM band and retransmit in FRS
(FM narrow band in 450 MHz approximately).
Regarding this issue, we have the following questions:
How can we control side A and side B on the same motherboard in
order to receive in side A and retransmit in side B?
How can we configure FRS functionality in the motherboard and
the TxRx 400 card? Which registers and how should be modified?
Thanks in advance
