I used an IC-7000 in my truck for quite some time before having
to retire it to my shack, so you'd think I would just know this.
I'm pretty sure though that the 7000 will remember one band in
addition to the standard Ham bands based on what was last used
outside of the Ham bands.
What you seem to be saying is that it now has two 30 Meter
bands as you use the band up/down buttons. Is one of them close
to the 30 Meter Ham band but not in it?
Try going to some other non-ham frequency range, such as AM
broadcast or something, then use the up/down band buttons again
to see if that's now the additional band.
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.
