Hi,
  When I run benchmark_tx.py with "-discontinuous" flag ON, I notice
the following problem:

   When the transmitter goes to sleep (for 1 sec), the receiver TIMEOUT (which 
is fine).
But then when the txmitter wakes up and sends the next 5 packets, the receiver 
consistently does not
receive the first packet (of this set of 5 packets). Occasionally, I see the 
rcvr does not
get the first two packets.
   So, I think there is some problem when packets are sent after a period of 
"lull"
which leads to very first packet (after a TIMEOUT) being lost.

   Can anyone think of what could be wrong with the ofdm implementation which 
may
lead to this problem?

   I am running gnuradio 3.6.2 on USRP N210.


thanks and regards
