According to RXTVlog,
Pick TV HD will be on
channel 147 on Freesat, the recently closed
Challenge+1's old number.

Additional: it seems that on Freesat the HD version of the channel will be the only version on Freesat that has the Premier League football. The SD and +1 will be showing the non-football version of the channel.
The HD version is on a UK spotbeam, the SD versions on Freesat are on a wider spotbeam. So the difference is rights-related.
