I was approaching class C airspace for landing at the primary airport
for which the class C airspace is designated and I listened to the
ATIS. The ATIS said "all frequencies are combined on
TowerFrequency". So I tuned to TowerFrequency and made
my radio call to approach. The response that I got was that I
needed to call approach on the approach frequency. So, I guess
that begs the question ... when the ATIS says "all frequencies are
combined", which frequencies are included in "all frequencies"?


Based on the tower's reply, it appears "all frequencies" means tower, ground
control, and clearance delivery frequencies. But that doesn't mean your
assumption was unreasonable.
