UMKA-1 SSTV over Stockholm 2025-08-30

The UMKA-1 satellite has turned on it’s SSTV transmission on 437.625 MHz FM Robot 36-mode. Strong downlink that should be possible to receive with a simple yagi without elevation.

Equipment used:

  • RX at 437.625 MHz FM
  • 2 x 13 el LFA X-Yagi (InnovAntenna) on at horizontal polarisation during this pass
  • AlfaSpid RAS az/el rotor
  • LNA Mini-70 from SHF Elektronik
  • LMR-400 coax
  • RTL-SDR v3
  • SDR-Console v3 with doppler correction of downlink and satellite tracking, rotor control
  • PstRotator for rotor control interface between SDR-Console and RAS controller
  • RX-SSTV v2.1.5
  • VB-Cable: virtual audio cable for piping audio from SDR Console to RX-SSTV. Set to 96 kHz and 16 bit.

Decode QO-100 PSK beacon

This is nothing new, but it is actually the first time I have done it. The PSK Beacon can be found on 10489,745 MHz and you can use the following Windows software:

IZ8BLY P3D Decoder. I have tested this one, and it works fine.

AO-40 Telemetry Decoder. Should work fine, but I have not managed to decode.

What you need to do with both these software is to “pipe” the audio from a receiver to the software. This can be done with VB-Audio or other virtual audio cable software.

Below is a short video during decode:

HADES-ICM telemetry over Stockholm 2025-04-10

Strong signal over 25 degree elevation, easy to decode. Link to decoder in post. Equipment and software used:

  • RX at 436.662 MHz USB
  • 2 x 13 el LFA X-Yagi (InnovAntenna) switched between horizontal and vertical polarisation
  • AlfaSpid RAS az/el rotor
  • LNA Mini-70 from SHF Elektronik
  • LMR-400 coax
  • Airspy Mini SDR
  • SDR-Console v3 with doppler correction of downlink and satellite tracking, rotor control
  • PstRotator for rotor control interface between SDR-Console and RAS controller
  • Kepler element number used: 63492
  • VB-Cable: virtual audio cable for piping audio from SDR Console to Soundmodem. Set to 96 kHz and 16 bit.
  • Genesis 200bd Soundmodem v0.03b and AMSAT-EA KISS Console, download from:
    uz7.ho.ua/genesis200.zip

HADES-ICM was deployed last Monday, March 31, at 7:37 UTC from OTV ION-SCV-017. Telemetry data shows the satellite is in good condition. The satellite has already accepted commands and now it is undergoing a testing phase. The final TLE is not yet available but you can use this one (Source SatNOGS):

HADES-ICM
1 98637U 25052X 25092.34373891 .00000000 00000-0 42496-2 0 03
2 98637 97.4434 347.3229 0004588 342.2991 86.6061 15.18376415 09

The repeater will not be active until we have its final TLE and the satellite has been fully checked. This can take several weeks.

The same software as for HADES-R can be used for demodulating and decoding. (Recommended Andy’s Soundmodem).

AO-73 FunCube telemetry 2024-04-16

Long time since capturing the AO-73 telemetry. Still very strong and easy to RX.
