[Programming for Repeater]

Hey, all.  New GMRS licensed person here.

 

I'm trying to use a local open repeater:

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.

Thanks for any help in advance!
