The radio will not be shut down for HTV berthing. I will see if I can get the problem resolved.

I expect this is a mistake on the astronaut’s part, or possibly an error in the post-contact procedure.  I’ll pass this on to the ARISS team in Houston.  They can get a message up to correct this.  At the very least, it should be resolved when the radio is turned on after the shutdown for the HTV docking on Tuesday.
