Neat idea! Nothing is really going to go through multiple buildings in a city, so your best bet might be the ham bands that like to bounce off the atmosphere, bypassing the city entirely.

27mhz can skip if the conditions are right, im guess i just find out if it works. Used some web SDR to check the CB band round here…not much going on so at least there wont be much background noise

  When you get skip on 11m, it usually goes halfway across the continent and nothing will be heard the next town over.
  
  You need NVIS propagation to get a signal to a nearby location. That only works on lower frequencies like 30m through 160m depending on solar conditions. The signal gets send straight up and bounces back down in a several hundred mile radius around you. There is a map that shows which frequencies will currently work for NVIS as well as the Local Area Mobile Prediction tool to help you figure out what frequency to use for a given time and location.

    NVIS propagation
    
    Is a interesting topic, basically what i am looking for. Problem being is that right now i am restricted to license free bands.
