Hey, all. New GMRS licensed person here. I'm trying to use a local open repeater: https://www.mygmrs.com/view?id=502 I can't figure out the programming for my BF-888S to save my life. I have the frequencies programmed in, and I can transmit to the repeater. However, I cannot hear myself on another radio of identical programming. In addition, more than 50% of the time, all I can receive is some loud "grinding" noise that sounds similar to the sound some of those old bubble pack radios used for an alert. Kinda an errrrrrrrrrrrrrr noise. I hear it randomly when just letting the radio sit, and often after I attempt to transmit. Am I doing something wrong with programming? I think I have the PL correct for receiving too. The owner of the repeater isn't in town, so I can't ask him about the finer details. Channel three in the attached image is my programming from CHIRP. http://www.7220ft.com/radio.PNG Thanks for any help in advance!
