I think I may need to go this route to get my local CW channel. I live in Waci and get the National DC feed but only in HD.

1. Create a custom guide list and select only those OTA channels (and, of course, any others) that you wish to appear in said list (this is the method I use):
2. After completing your initial AM21 setup, under Edit Off-Air Channels, select only those OTA channels that you wish to globally appear in any guide list:
