I agree with what Jim said but I would like to add another comment.  Any 
source that is Q5 at one location and unable to be heard at another 
location 200' away is DEFINITELY close to the Q5 location.  It would be 
humorous and slightly embarrassing if the power supply that runs your 
QS1R was the noise source.  My vote is for a small wall wart type power
