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!
