I am sure KBDX is brokering time. In that case, competition only matters to the entity buying the time. Likely they have a client that is about to go live and they're giving them a few days at no charge to build a little interest. Pretty much how my station does it, once the contract is signed and check cleared, they go on the air for the rest of the month with the paying beginning at the 1st of the month. This might be their only account at the moment or they may have leased the entire broadcast day to one client.
