r/amateursatellites

like the title say has anyone used vr to receive satellite images?

this link shows the person receiving metop weather images and dvb-s video feed all on one vr headset. I never thought was possible as everyone in the ham radio community seems to carry old laptops and heavy dish units. The user seems to receive using unique handheld antenna while at the same time using augmented reality to process. I think this is excellent!

Hey everyone, I'm new here, and just started messing with an RTL-SDR blog v4 a couple of days ago; so far, I've been able to pick up ADS-B with just shy of 100km range, and of course plenty of broadcast FM and DAB. After trying and failing to get a working decode of a tetra signal, I thought I might try some weather satellite passes (just my SDR and V-dipole bc no filters/LNA yet). Although I was fairly disappointed to hear that NOAA's VHF weather satellites are all gone (r.i.p.),

I waited around for a decent meteor pass. On my first go, I got functionally no signal, mostly my fault because of leaving the AGC on. For a second go-around, this time a better pass (max 83º), I got what looked like a bit of a stronger signal but still no picture. I've included a few pictures of my setup as I think that the railing might be the issue, but please let me know if there's anything you can spot that I'm doing wrong.

(let me know if i should upload my recordings of the passes or screenshots of something if they can be of use)

Hey all! I've received NOAA APT, just pulled a Meteor LRPT the other day, and I'd like to go for a GOES image next. It seems like a cantenna on a dish is what I'm going to build but I have one question.

When I solder wire to the connector inside of the can, does it bend to travel out of the can? (I know it's not going to be long enough, just saying it that way for description purposes)

OR, it seems like most guides are saying to solder the wire so it is perpendicular to the can's side? In this pic it looks perpendicular

La première est retourné pour que l'Europe soit dans le bon sens, pour une réception de 309 secondes au total. Vous en pensez quoi et quelle amélioration je pourrais faire ?

Pour se que sa interressent, j'ai utilisé l'antenne de base du sdr v4 et un trépieds d'appareil photo pour faire le V à l'envers. Je précise que j'ai reçu le Meteor M2 - N4

Forgive me if this has been answered previously, I did a search or two and came up dry, but I also have some vision impairment (due to a recent injury and I am recovering) so it's entirely possible I couldn't see.

I was thinking about buying a FB MP dish or something off eBay when I realized the previous house owner had two of these near the back corner of the house. So they're mine now (I've been here a while and the previous owner is dead so I don't think they're coming back for them).

Would these work for any type of satellite (other than the ones intended by the manufacturer)?

I have been listening to the airwaves and am now working to get a technician license. But I am deeply interested in radio astronomy and satellites so I figured I can use one of these to listen to something out there.

I have a few SDRs and a can do attitude. Lol, man it's time to mow again. That rain is a blessing to the land, but that grass grows like wildfire lately.

I know there has been a lot of discussion on whether a bunch of Yaesu mobile radios are full duplex or not. It's been confirmed they are including the FTM-150, FTM-300D, FTM-310D, FTM-400D, FTM-500D, and FTM-510D. See the attached picture I got off the AMSAT Facebook group.

I've used my 500 in cross band repeat mode, and yesterday coincidentally while transmitting on a local net on 2m I received another operator on 70cm. I then fully tested it while listening to that net on 2m and transmitting on a 70cm frequency.

I'm going to try to work a satellite on it next.

Still working on this folding antenna, however the focal depth does seem like it's a bit deep.

diameter is 1214mm

Depth is 609mm

When I do the math, it's only coming out to 165mm

Can anyone confirm my math is correct?

Helicone antenna was printed from open source files available online, SDR used was a B210 USRP compatible, Software was Satdump.

Used a novel filter LNA design involving triple SAW filters in a SAW-LNA-SAW-LNA-SAW configuration, significantly reducing frontend overload from out of band signals on the first LNA

SAW filters are custom 1.7ghz±15mhz Insertloss 3db filters ordered from HCI.

Carrier board is modified COTS LNA board, replacing the onboard SAWs and adding pads for a 3rd SAW filter by PCB cutting and modifications.

Overall performance meets and exceeds that of COTS Sawbird GOES, in terms of overload tolerance, noise factor, and passband selectivity for 1.7ghz satellites of interest.

edit: last image is of METEOR pass, first picture is of GK2A LRIT reception

seems to have some small issues, but will iron it out as I go along, will post the plots of performance once all is ready!
