Topband: TX ANT TO RX ANT COUPLING

I have been following the thread with interest.  I have a K9AY and a DO loop 
located within 60 to 75 ft of the TX vertical at our summer home. 
Interestingly, I find both these antennas very quiet with no sign of noise 
being coupled to them via the TX antenna.  I work a lot of DX from this 
location on topband using these loops as well as a pair of Beverages, both 
of which also pass fairly close to my TX vertical and both of which are very 
quiet.

So, why am I not hearing this noise many are experiencing?  The TX vertical 
is a 60 ft toploaded affair and I do not de-tune it on receive.  All I have 
done is to run all the feedlines for both RX antennas and the TX vertical 
underground in different conduits to a remote switching location.  Someone 
please tell me why I am missing out on all the fun of having noise on my RX 
antennas.
