Do your two antennas have different Schedules Direct lineups?  I have two
HDHR dual tuners and channel 2 (31) can record from any of the 8 virtual
tuners that gives me. I don't think the HDHRs know how many antennas but if
they are pointed in different directions perhaps they are actually not
picking up the stations. I am probably not being that helpful and it has
been a long time since I had multiple antennas pointed in different
directions so the memory is weak. At one time I had three antennas, one
north, one south, and one south east. It is no longer necessary as PBS
broadcasts the same programs on their two locations and NBC is now has a
transmitter both north and south of me.

So my advice is if you have antennas in different directions you reconsider
that in light of where people are transmitting from and if you have both
antennas pointed in the same direction then the HDHRs should not be able to
tell the difference.

One thing you might do is just delete everything and do a full scan. That
will probably leave you with one station you don't want but perhaps you
will get a prompt to discard the weaker one. Otherwise, just scan delete
the station and scan for the one you want. I didn't do it that way because
I don't want to get all the stations that I can, like the ones in languages
I do not speak.
