Subject: why does my radio reception change if i stand near radio?

i use a stereo with a cheap T antenna, also portable boombox with extendable 
antenna.   i live out in country.  if i tune radio and walk away,  often the 
quality of reception dramatically changes (for better or worse). I do not have 
implanted electronic devices.  I must be emitting RF waves.... but that seems 
crazy !!  This was same  whether in room with rug,  or in concrete floor 
basement so I doubt static electricity as the cause.  Tx much.
