Voice on CH70

I turned on scanning on my VHF.
It locked onto Ch70 with routine voice traffic from Falmouth Coastgaurd. I'm not sure if 70 was one of the channels within the scan.

I thought Ch70 was data only...

Can anyone shed any light? Don't be afraid of going technical with me - I feel I really should be able to work it out, but haven't done so yet!

I’d get your radio manual out and work through the scan set up and DSC part carefully... my guess is there is something about how/what your set displays that you’ve misinterpreted.

Can you select channel 70 as a channel on your VHF? I am nowhere near a VHF at the mo but I don't think it should even appear as a channel you can select.

But I assume you can't transmit on it?
