I've looked over the rules for AM band CC broadcasting. The inference from some here have made it look like CC broadcasting is only for education campuses, but, in fact, there are no such stipulations in the FCC regulations governing CC Broadcasting.
Therefore, I'm going to go ahead and start working towards the goal of establishing a CC broadcast station, which will hopefully help solve the problem of getting my programming into buildings in downtown Friday Harbor. It will be at the low end of the band of course, right around 610kHz, which is very far from the 1650kHz used for the stick antenna, and should pose no problems for interference with each other, and so they need not be sync'd.
I can use some help, other than the LPB manuals, which are great, but a long ways from describing what I'll need to do in, say, a 4- or 5- block square area without o many cable runs. I'm ... hoping RF Burns can continue the blog started back in March.
