Because this is second hand buy, I wonder if chirp is working with E2820 or there is some difference between 2820H and E2820 or there is some problem with the data port of E2820.
Looks like you selected the radio model specifically. Can you use Icom/Auto-Detect and see if it logs a message about an unsupported model?
