[Discuss-gnuradio] garbage signal when TX is enabled

[Jung Il Choi]

Hi all,

I am using two RFX2400 daughterboards on USRP1 to implement TX/RX on each 
daughterboard.
When I do ZigBee packet transmission, I found that there are always some 
trailing garbage signals after each packet. The trailing garbage has strong 
fixed I and Q values (slightly changing) which lasts about 80 microseconds. The 
cause was TX/RX switch time. When I do set_enable so that TX is always enabled, 
I see those garbage symbols throughput the gap between packets. 

So, the question is whether there is a way to avoid this. Because I am doing a 
packetized transmissions, it is a pain to feed all zeros between packets.

Thanks,
Jung Il
