I am a retired Public radio engineer. I am retired from two Universities. I worked at the radio stations for over two decades. At the second Radio station our transmitter was co-located at the PBS transmitter. So for over ten years I had the opportunity to observe the transmitter sites of both an NPR and PBS stations. In the time I was there, the television station replaced their transmitter 3 times. While that was going on there was no money for replacing my 30 year old transmitter. Maybe I am that much a better engineer than theirs were. Well, I must admit that during that time the change from NTSC to ATSC occurred. That change should have been funded outside of the regular equipment replacement funding. My point is that television is funded far in excess of what radio needs. A radio station should not be required to keep repairing a 20 to 30 year old transmitter when the television station is over-funded that they can replace theirs twice. I AM erring on the conservative side in saying that they replaced their transmitter twice during that period.
I am an engineer. I therefore not a writer. I tend to be terse. I am not a persuasive writer or speaker. I must insist that you take my statements and observations as real and more critical than I am stating here.
