Thanks for the explanation. I managed to get the system working by
introducing a delay before every packet transmission. I know it's a hack
but that's the quickest method I can think of. The minimum delay that I can

turn-aroun

I have been troubleshooting an issue with possible packet relflections and
cannot figure out the cause. I am running tunnel.py on two USRP2s that are
cabled together with a 20dB attenuator between them. The settings I am using on
both sides for tunnel.py are:
Tx Gain: 15 dB
Rx Gain: 10 dB
