The NACs have not changed. Have you monitored them with this radio previously? If so, the following is old news to you.
I live about the same distance from Mayfield as you and cannot pick-up the Graves tower. You may have better luck with the Hickman and Ballard repeaters. If you haven't yet done so, enter all the Post 1 towers. Sometimes, the closest tower isn't the best for your location. Also, ensure that the freqs are programmed as FM, not NFM.
Thanks for the information I am new to trying to listen to them and didn't know if I had done something wrong or not. Do you hear beeps when they are talking that can of distracts from what they say. I entered the universal nec that is like carrier squelch and did hear them but also get the beeps that makes it hard to understand all of what they are saying.
No beeps for me. Sounds like a setting unique to your radio. I am not familiar with the Vertex and can offer no advice concerning it. I am sure someone in the Scanners and Receivers Forums can assist you.
