Article said, "...the main requirements would be adequate power and storage space for radio equipment..."
This seems to be magnifying these issues solely to create drama.
The "adequate power and storage space" are pretty much irrelevant. ALL the radio hardware needed to provide Amateur Radio connection is already designed and integrated into the ship as part of its regular radio inventory. All they have to do is set the appropriate frequencies which are well within the spectrum of frequencies already available to the radios and antenna arrays on the ship.
Similarly for the power requirements. Communication to the moon and back on these frequencies actually requires very little power and should be well within the capabilities of Artemis' existing energy budget.
