DOSAAF-85 transponder activation
Good day! Satellite DOSAAF-85 turn on transponder (linear, inverting) on for testing purposes. UPLink 145965KHz +/-30 KHz DOWNLink 435640KHz +/-30 KHz BEACON 435605KHz TLE: 1 44909U 19096E 20120.96346743 +.00000010 +00000-0 +00000-0 0 9999 2 44909 082.5239 027.5343 0217449 340.2089 019.0669 12.79706663015985 Try it! -- 73! Igor, RW3XL
The new amateur payload DOSAAF 85 appears to work very well. Doppler measurements confirm that it is indeed object 44909, 2019-096E. The satellite identifies itself as "RS44" (i.e. Radio Sputnik 44) on its CW beacon on 435.6043 kHz. The passband is about 63 kHz wide. It may also have a downlink between 2400 and 2485 MHz. The frequencies of RS44/DOSAAF 85 have not been IARU coordinated. The satellite is in an elliptical orbit with a perigee of 1175 km, an apogee of 1511 km and an inclination of 82.5 degrees.
The payload is apparently attached to the Breeze-KM upper stage of a Rokot launch vehicle that launched three Gonets satellites on December 26, 2019. It was originally expected to launch in 2015. It is based on the Yubileiniy platform.

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.

The failure of RS44/DOSAAF 85 (also known in Russia as "Radio 2017") to separate from the Breeze-KM stage also prevented the deployment of BLITS M1, an experimental passive laser reflector satellite.
With RS 44 now attached to the Breeze-KM stage, its gravity gradient stabilization boom can not be extended, because that is at the side where the satellite is attached. But fortunately all radio antennas are at the end of the satellite that points away from the stage. Therefore the radio equipment of RS 44 is fully operational and works well. The CW beacon on 435.604 MHz still only sends its ID "RS44". Maybe later some telemetry can be sent as well.

Oh dear - this also happened with RS25 which was launched on the same time as SSETI Express ...https://space.skyrocket.de/doc_sdat/mozhayets-5.htm
RS25 never became active but RS44 is certainly working well!

Dear All,
Confirmed Graham working well.
Made a quick QSO on RS-44 with my good friend Kob (E21EJC) which I contacted on a few birds in the past, really nice.
Also Rx 3B8FA on same bird, seems working fine so far.

Great sat!
I suffer for linear pol antenna (I'm going to build new cp yefa when I'll be able to get alluminium, after lockdown) but I've completed qso with 2M0SQL, R9LR (3900km) and DJ8MSD.
RS44 has an orbit similar to AO-7, operating mode like FO-29 but stronger signal, what more? :-)
73, Lapo IK5NAX
Does this mean it will be in orbit for quite a while?

Great sat!
I suffer for linear pol antenna (I'm going to build new cp yefa when I'll be able to get alluminium, after lockdown) but I've completed qso with 2M0SQL, R9LR (3900km) and DJ8MSD.
RS44 has an orbit similar to AO-7, operating mode like FO-29 but stronger signal, what more? :-)

Does this mean it will be in orbit for quite a while?
I think so. It's a satellite with a large passband, many qso at a time. I don't know about primary payload... let's hope well.

I thought it was reported to be attached to the booster rocket, which would represent a fairly significant source of drag. But, at that altitude, it should take a while to come down.
Here's hoping for a long active life!

p.s. BTW, object 44909 shows as satellite "BREEZE-KM R/B" in gPredict, from Celestrak's data.
