An h3 with issues? Really? So you seam to have 2 things going on.
1 Not hitting the repeater with any of the radios. If your programming is correct the only other thing would be distance/line of sight.
2nd measuring swr on an ht is not accurate at all. But it should atleast do something similar to the others. Bad radio? Probably.
id send them all back asap and get some better radios. Note, better, not more expensive.
