Spectrums Gallery

Please click on the satellite orbital position below for its corresponding Spectrums. Most of these pictures were taken on 5/14/2025. The ones that look like line traces are older. The transition to new post-5G frequencies is pretty much completed now so these spectrums are fairly stable.. I didn't get the Mexican or Canadian birds this time. The C-band LNBs have "blue" filters (4000-4200 Mhz) Span is set to 500 Mhz which is 50 per division. Images are centered on 3985 Mhz Cband. Cutoff from the filters is pretty sharp there. Ignore frequencies on Ku band pictures. I didn't change the spectrum analyser settings for those. Note that on C-band, the spectrum is reversed so downlink frequency gets lower to the right.
