Some of it may be power. In general, most antennas are reciprocal -
i.e., when your antenna is receiving a station well, you will probably
transmit to him well also. But it you're running 100W and he's running
1500W, if everything else is equal (and admittedly it seldom is) you're
probably hearing him 12 dB better than he'll hear you. Then there is
the question of QRM - he may be hearing a lot more of it from areas
where you're don't have propagation at the moment.
So if you're hearing a station loud, that's good. But if you try to
imagine what things sound like at his end, I think you'll find the
answer to your question.
