GemsTV1 is no longer on Freeview channel 44. You will need to rescan you box (a full rescan) to remove the channel placeholder. The channel used to air 7pm-9pm daily. Gems TV programming will however now also be shown on Netplay TV on Freeview channel 49 from 4pm to 9pm daily, and Gems TV is still available on channel 43 from 9.45am to 12.45pm daily.
Gems TV have extended their hours on Freeview by two additional hours – but on a separate channel name and number. The new slot is called Gems TV1 and their existing Gems TV slot also remains. This means Gems TV will broadcast on channel 43 from 9.45am to 12.45pm and on channel 44 from 7pm to 9pm. The space Gems TV are now using 7pm-9pm looks like it came from the space freed up when The Jewellery Channel left Freeview earlier this year.
