[GreenKeys] FRF FSK conv. (was - Two eBay Novelties)

[David Christ]

I have no specific knowledge but I suspect that the issue was that the unit's oscillators were not well enough shielded and there was concern about detection by RDF (radio direction finding).  That is why the shipboard warning.  Not such an issue for a shore station.

Purely a guess
