The booster will "fill in" the areas that are shadowed, or blocked from the Morena antenna, when and if it ever goes to legal power.See Radio Locater for their coverage area. They are a limited signal to the north under any circumstance.
The booster was on/off many times from Wednesday, and had music on at night. The main site power was reduced during this time, but is back up to its underwhelming level. Daytime RF testing IS frowned upon by the FCC.
I'm not sure WHY the County of S.D. would allow this commercial operation to be located in Summit Park,temporarily, or at all.
