Thanks. I was only looking at the actual channel number (57-2) in the spreadsheet. Let me give that a try. Do you know if I have to double reboot to clear out the channels first? I used a Colchester, VT zip (05439) to make the channel appear with a different guide.
You might have to clear it. But I would run the zip first and check the results. In my setup, it will sometimes give me a second channel with the same number (57.2 in your case) and sometimes not. So run the zip first and if you don't have it, then clear the AM21 with a double reboot. Since you have a 57.2 channel already established, and your matching the RF34 channel number instead of the 57.2 channel it probably won't pick it up and you will have to do the double reboot clear.
