VGC VR N76 connection

I have the VR N76 and I can’t get it to connect to the digipeater. A friend has one and our radio settings are the same. (i think) I also get a message “the current channel does not support sending” on the radio. I’ve even completely reset the radio to factory specs and started over.
If I delete my call out of Radio mail can I resign up and try those settings? Any ideas ? Thanks, Mike KD9BKU

Hi,
Do you use the last firmware ?
