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.
