Good morning, newbie here too. I have a similar issue with a repeater. I have programmed it with all the info given. I key it up and it seems as if I do reach it, but I don't get any sound back after I let go of the ptt. I do get a the green light to turn on indicating I reached it though.
I have other repeteres programmed that are further away and I do hit them no problem and I get a sound coming back notifying me I keyed up successfully
