I know an elderly set of identical twins who live together on a very remote island, and spend their days doing this sort of thing with a 5m dish. Watching this reminded me of their antics.

Remember kids, like a gaming PC, you can actually add 3 dB of gain when you add RGB lighting to your satellite dish, lol. Anyway, a really nice deep video about GAC, really like it! Btw did you consider to add counterweight to the big dish so you don't have to lift most of the dish weight? I feel your pain just by watching and hearing the squeak 😅

Remember there are collaborating receiving stations all across the globe. and the signal can be received anywhere within the footprint.

Hey man, cheers from Poland! When was this video filmed? Everything melted here for us already. If there's still snow in Czechia I seriously need to move to you guys

It sucks that the GAC mode is only transmitted when in view of Svalbard, but I wonder if it dumps to Wallops or Fairbanks at all. Might be something to try out

@maosolny5856 6 месяцев назад

I never offset my center frequency. I m using RTL SDR v3. I dont see signal losses when satelite is in the peak elevation.

@t0nito 6 месяцев назад

I didn't offset either but when the satellite passed peak elevation I would always get a dropout exactly over my location and I didn't know why, someone then told me it was because the carrier crossed the DC spike causing a momentary loss of sync. After I offset the frequency by 0.5 Mhz the problem went away.

Do you think GAC is receivable from Portugal?

@dereksgc 6 месяцев назад

that might be far too south for this to work, but if you are in portugal you may be able to receive HRIT from the GOES-16 satellite instead

@t0nito 6 месяцев назад

@@dereksgc that's too bad, goes 16 is only at 8° Elevation from where I live, but I live in a valley so the satellite is behind a hill 😅. Also maybe my modified wifi grid antenna is too small for that. But I do get peak 17dB with NOAA and Meteor satellites and around 14db with MetOp. Are you a member of the APT Group on Facebook? I post there regularly.

As West Australian I had the same question but as a West Aussie I now totally understand. These have been some great videos bro, thank you so much for all of them. They are really helping me on my sat journey @@dereksgc
