Jim Franke 0 Report post Posted April 5, 2021 I replaced my 250 Plus with a U6 for Mac Big Sur OS. With exhaustive autotune scans on both ASTC and clear Qam I can't get a gateway channel. The 250 had a channel change select that I could put on channel 3. How can I set channel 3? Quote Share this post Link to post Share on other sites
