I am sure someone has tried to find out the maximum transmission
using USRP2. For example, I am interested in the maximum transmission
in the following setting:
USRP2 with WBX, 400MHz/900MHz, outdoor, los, static,
benchmark_tx/benchmark_rx with default except tx_gain=25 (maximum).
We are interested in extending the transmission range by adding external
amplifier module. If anyone can share the experience, it would be
