It is good to know that having both + and - on at the same time in the display for programmed offsets is OK.  That knocks another concern off my list.

Rich, you asked earlier if I could do a factory reset on the radios.  I have done many resets on all 3 of my radios ( 1 each UV-5RHP and 2 each UV-5R8W's).  At one point, following a reset of both 8W radios, I downloaded a new .img file from each of the radios, copied just my test repeater details from the CHIRP Repeater Book .img file and pasted that single line item into my two radio .img files , then uploaded those files back into their respective radios and performed a test with the same results.

Right now I have two concerns.  First, when I export a .img file to CSV, (including the CHIRP provided Repeater Book file), the resulting .csv file shows 88.5 in every empty CTCSS frequency cell (columns G and H).  See embedded image.  Am I correct in assuming that for simplex channels with no CTCSS, the Tone column has no entry, so the radio won't even look at columns G and H and for simplex channels with CTCSS, the tone column has TSQL, so the radio will look at both columns and for repeaters, the tone column has Tone, so the radio only looks at column G?  If that is a correct assumption, then that knocks another concern off my list.
