The other Urban broadcaster (I thought it was Inner City, someone corrected me earlier but I forget who it was) lasted just a few months. And again, WAMO was still around.
I am rooting for you guys but unless you can get a translator, I think your best bet would be to find some ministries that want to buy some blocks of time.
The new WAMO proves what can be done with the right translator, as the rules allow them to be a virtual Class "A" if maximized.
