    Bob in general a person living in a city will have a Ham station 
nearest using the band(s) that are open. Today that is all under 10 MHz 
most of the day. As the sunspot cycle grows the higher bands are 
popular. If you have one of the about 60 moon bounce stations near you 
then you might get some interference.  But as a rule...
