Has the NASA Transponder's Power been reduced?

Post by belter-one » Sat Jul 04, 2020 2:00 pm

Hello,

I noticed that this morning that the NASA transponder on 127W (3920 V, DVB-S2, 8PSK, 28068-3/4) went from SNR 16.2 yesterday to SNR ~9.0 today. The Reelz transponder (3820 H, DVB-S2, 8PSK, 30000-5/6) SNR has remained the same at SNR 12.4. Has anyone else noticed NASA's transponder SNR being reduced today? Any feedback on this will be greatly appreciated.

May the Clarke belt smile upon your dish,

NASA transponder SNR is down for me.

On my 12' dish I get

Reelz: 17 dB
Nasa: 12.3 dB
ESTV: 16 dB

There could be adjacent satellite interference or NASA needs to crank up the power. Those with smaller than 10 footers probably aren't even getting a whiff of the signal.

Awesome!

Thank you for this very useful information. Twelve foot dish! I am not worthy! :worshipking:

Many thanks,

There is another NASA feed on Intelsat 14 (45°w). The 4K feed on 101°w has been discontinued for now.

I have an 8 foot dish and I get it. I think the transponder changed. Because I had two transponders for nasa and the next day I only had one and it was coming in at 77%.

everyone suffering the same problems but it will recover it after dust in our atmosphere gets cleared by weeks later ...its not only 127w..but all satellites loss 3.5 SNR power but still operational with that like nothing change in signal picture degradation...even with 9.0 snr that supposed to be 9.5 SNR minimal for those channels ...still operating without issues with picture ...just dust cause signal to split in smaller beams...its reflected sunlight, just like mars if person lived there...cause cooler nights and hotter day time ...just wait for rain storm will also clean up the atmosphere

have anyone try to look up the night sky and seen moon .....sand does amazing things to our atmosphere ...cause our skies to illuminated like scatter led lamps across the sky than normally focus one location...hard to see the stars in the background but i do enjoyed seeing jupiter in naked eye

Hello all,

The lost SNR on 127W is back. I will be checking other satellites later, out of curiosity later.

Have a great Clarke belt day,
