is 145.800 an IARU "illegal" frequency?

When voice downlink is set for 145.800, theoretically falls within the IARU border for amateur space communications. But since the IARU bandplan has right underneath the amateur space band on 145,800-146,000 the Region 1 Repeater 12.5 KHz slots (R0 - R7B) with the latter falling on 145,787.5, when ISS sets and doppler draws the transmission frequency maximum 12 KHz down, (due to enormous relative to observers speeds ISS excibits, a result of a lower than average spacecrafts orbit)

mutual interference with the repeaters is assured.

Let me ask for a downlink frequency change, then. Maybe the packet frequency at 145.825 is best suited for voice downlinks, too.
