[amsat-bb] DOSAAF-85 transponder activation

[Paul Stoetzer]

RS-44 has been added to the AMSAT Linear Satellite Frequency Summary:
https://www.amsat.org/linear-satellite-frequency-summary/ and the AMSAT
satellite status page: https://www.amsat.org/status/

It should also be added to AMSAT's keps distribution by this evening, which
will update a number of tracking apps with the satellite and our own
website's satellite tracking page as well.

As per custom, we will use the satellite's Radio Sputnik number to identify
it, so it will be listed in AMSAT sources as RS-44.

73,

Paul, N8HM
