I've been thinking this over and rereading the downloading glossary entry. There are 2 paragraphs that talk about a card other than a facility or site downloading a personnel/ship/equipment, and neither clearly apply. Those paragraphs are:
downloading glossary entry wrote:When a card other than a facility or site allows you to download a Ship, Personnel, or Equipment card, but does not specify where you may report it, you must obey all normal reporting requirements and report the card to a place that card could normally report (e.g., to a compatible facility and/or an appropriate site, in its native quadrant). For example, Defend Homeworld allows you download a SECURITY personnel, but does not specify a destination. You must report the personnel someplace it could normally report. In most cases this will be a compatible facility in its native quadrant; however, a Borg player could download a SECURITY Borg aboard a Borg Cube (which allows reporting aboard), and a downloaded Luther Sloan could report anywhere, as specified by his skills.
When a card other than a facility or site allows you to download and report a Ship, Personnel, or Equipment card to a specific destination (such as "download to here," "to this location," "to one of your ships," "to an outpost," etc.), you must report the card where specified; normal reporting requirements related to where you play the card (e.g., a facility, appropriate site, native quadrant) do not apply. A special download icon also implies a specific destination ("here").
The first paragraph doesn't seem to apply because
Gagh Tek Or? does specify a location the personnel
may be reported to. I think this is the paragraph that is intended to apply and if it was phrased without the word may, it would be more clear. The second paragraph doesn't seem to apply, since
Gagh Tek Or? doesn't say the downloaded personnel can't report somewhere other than the site.
In my opinion, I think the intent of the (may report to that site) clause was to clarify that the site would be in play when you download the personnel, so you could report it there. If I were to use the card for tournament play I would operate under the assumption only alpha personnel may be downloaded to the site with that function. If you're planning to use it in an event and this is a significant aspect of your deck, I would recommend talking to your TD to see how they would rule.
