Is it possible to stitch together GOES-16 and GOES-17 full-disk images?

So yesterday was my first successful reception of GOES-17, and with it came other downlinked data that was shared from GOES-16 and GOES-15 (albeit at lower resolution). That got me thinking since it appears to be able to relay images from Himawari-8 as well, could you stitch together enough full disk images to create a "panorama" of the earth on a Mercator projection map? Presumably, you'd also need images from Meteosats 11 and 8 to complete the full wrap-around, but that's a separate problem. I also don't know if they all take images at the same time so there might be some weird artifacts where the images overlap.

Looking for a cheap SDR that can transmit at 1.2 — 1.3ghz

As I don't need the full 6ghz range of the HackOne which would be my preferred option, I wondered if there is anything in the market that can broadcast in this range.

Hi! What is the current draw please? I would like to use with HackRF which provides 50mA.
Thanks!

RF Analyzer — recording IQ files

Hi there, i just tried to record NOAA 15 with my shitty V Dipole and RF Analyzer for Android. It sadly picked up mostly noise, but i want to look at the recording. The output files are .iq, what do i do with those? I tried to convert them to .wav with sox, and also tried loading them in SDR#, but it says wrong filetype (since they're .iq and not .wav).
Any idea?

Wire for Dipole V Antenna

Hi guys, I've been trying for a few days to receive something else than noise. Since I've got no roof access, I'm going outside for the transfer. I've built a V Dipole from thick copper wire, but didnt get a good connection to the coax. For my next try, I've just taken some copper wires since I've read that the diameter doesn't really matter for receiving.
Do i need to strip the wires, or is the plastic insulation no problem?

Also, I'm planning on using my android with the RTL-SDR driver and RF Analyser, any tips regarding that setup?
