Hi guys, it seems that in a contest like NAQP where presumably almost
everyone is running the same 100 W power, you should be able to hear the
other guy at the same level he hears you. Even if the other guy has a
$25,000 dollar beam, and you have a simple 10 foot random wire, the
weakness in your transmission ability will also weaken your received signal
just as much in the other direction. So if you can hear him, it guarantees
he can hear you. (Unless one or both of you has separate receive and
transmit antennas, or the receivers you are using are of very different
quality.) Does that make any sense?
