I have been listening to the Wyoming county sheriff and many times now they say they are going to IRP . I have now for years been listening to them with no problem. But here lately when they say they are going to IRP I have not been picking up everything as I had before. I still pick them up on IRP but not all the time like I use to. So , here is my question. Have they gotten some new IRP frequencies?? I have an outdoor scanner antenna. Also a preamp that has adjustable gain. I use the pre amp because I have about 70 foot of line. I am using the best coax with the lowest line loss. I have three scanners going at the same time. The pro-197 and the whistler trx-1 and the Bearcat 396xt . Sorry to be so long on explaining this but I tried to cover all bases to give you guys an idea of my set up.. This site and you guys are the best. You all have been vey nice to this old man and I don't know what I would do without your help. Thanks and have a blessed day...
