Hello Stu,
Yes, I learned about that capability from a Norwegian TV show ( Norsk lyttestasjon viktig brikke i Falklandskrigen - Brennpunkt - NRK , I use a translator...)
However, later I talked with former Soviet army personnel and with a former Polish navy officer and they told me that is unlikely, due to good ciphering and, most important, because all Soviet recon satellites had no radio links with earth stations to transmit gathered information.
Mr. Aldrich´s book gives more info about that?
Regards!
The book simply states that throughout the conflict the Norwegian signals intelligence base at Fauske regularly intercepted the Soviet satellite intelligence data. It doesn't say how they did it but if what you say about the Soviet satellites having no radio links is correct then one wonders if the satellite intelligence recovered by the Soviets after an overflight was then being transmitted by other means upon which it was compromised?
