We are interested to operate our USRP N200 radios in TDM. In other words, we 
want each of our radio to transmit and receive at the same frequency. Since we 
expect very high self-interference in this case, we would be interested to play 
a little bit with the ADC mute option. Could you provide us some pointers on 
where to modify the FPGA code to do this? Also, how much realistic/feasible it 
sounds if we want to control ADC (on/off) switching from within the GRC flow 
graph (at the very least, we will expect some latency associated with this 
operation).


Thanks in anticipation,
Mahboob
