I bet that was me posting to GMRS Amateurs FB page about split codes. There are repeaters in the Denver/Front Range area that all say they use split codes on their information page on this site. I have spent three evenings reading up on the issue. I already have a Midland MXT100 that's been sitting in the box all year, but when I finally set it up in the truck, I found out that it can't do repeaters, let alone split codes anyway. So I've ordered a 50X1, and I'm hoping it will accomplish the task. Sent repeater access request last night, and the radio will show up some time this week. -Bill WRDM784
