Even if the Herald took it on as a vanity project, and assuming the Herald is not exactly swimming in money as the newspaper industry is going the way of the blacksmith..... and they could get it for short money, moving the main studio to Fargo Street, there is still that pesky issue of the transmitter site, which is rumored to be a huge expense.
Nobody on the last 30 years has been able to make that station viable in the market, and with AM signals being hampered by increasing levels of interference, it isn't going to get any better.
So unless someone has a grand plan to move the transmitter, or get a translator ( in this market !) 1510 is a station that has no bright future.... How do you make it break even?
