Somehow in all my switching this past week chasing the VP8, between CW SSB and FT/8, I accidentally added an extra 30 meter screen to the "Band" up and down. That would be OK except when I try to change it it reverts back to an unusable frequency hi. How did I do it or how do I erase it? I can't seem to find the answer. I see it in memories but nothing about removing it.
