New comer to the forum...
I got my H3 in the Ham version and reprogrammed it to the GMRS version and the weather channels, 11 of them were right after the 8th repeater channel (RPT8). I actually took them out of the scan function because I have 2 active ones and it would always break up the scan. I didn't have to program anything to get them in there. GMRS Version 240229 on my H3 (setting 42).
