TronxII

Might be the last ones which will still operate after a couple of high altitude nuclear tests wipe out some of the satellites. We take these satellites for granted like we believed that electric power, security, peace, cheap food and progress would always be there. But big parts of Europe have already no more GPS over the baltic sea, the electric grid breaks down, riots ...

Today I modified my antenna, which was horizontal strips of 0.2mm thick and about 1cm large. My idea was that the signal comes from above and therefore I turned them horizontal. It seems however that this was not a good idea. In vertical position, a noaa15 pass was received better than the days before. Comparing the satellite picture on the right with the commercial weather radar website picture on the left, I would say, there is even more information in the noaa15 picture. Still my antenna setup is not optimal. I'm not getting the nice signal in the waterfall like you posted in the other thread. So here is a picture how the antenna should not be positioned - horizontally, but the metal strip should be turned 90°

This reminds me of the weather report pictures from the early 1980s in TV, they had such pressure maps.

Not sure anymore what satellite the previous picture was. The generated json always says noaa15, no matter which one passes. Thanks for the website, with this I could capture an 80° elevation pass of noaa19 today. However it gave me only a useful signal when the satellite was quite high, like above 30° it started to decode. Only received some clouds in Antarctica LOL. Means my antenna is suboptimal. I'll try to play around with this antenna first, and then maybe the bandfilter with amplifier from Aliexpress. But over 20€ each! Glad that I'm not a HF affectionate, this must be quite an expensive hobby. I saw passive ones with only RLC which cost around 5€. That's tempting, but for 5$ I could order 5 PCB in China and make it myself ... Would be a good justification to buy a set of smd inductors.

Why is this?

On facebook they posted screenshots of second hand Neta V in china, all sell around 60 - 80 kBaht. So there is still a lot of room for discounted netas. 300k for a car without warranty, spare parts and service points but with a history of failures in all components ... not sure how many they will sell at this price

I'm in Spain. My antenna was a dipol for 162MHz, now I cut new metal strips and checked resonance at 137 MHz with a VNA. Its probably the best I can get before making such a complicated antenna like yours. With the new antenna, there is sufficient signal. The signal can be seen in the waterfall right and left to the actual frequency, and audio can be heard. This was not the case with my old antenna. The pictures of the clouds only are not that interesting, but the satellite also measures infrared or something and then colors the rain clouds. These are really nice. Thanks for your help with this, and I put my antenna here not because it's beautiful, but that others will be encouraged to try. Its minimal effort to make one.

OK thank you for the instructions. Following these guidelines, I did receive something from noaa15, although no idea where this is, and no idea, if this picture is from the satellite or if this is some map overlay from the software. The next satellite noaa19 gave some islands which I cannot identify either. Therefore I imagine that "3 - Your antenna is not suitable (what antenna are you using?)" is the next thing to address. I'm using a dipole built some time ago for 162MHz for AIS ship position, which worked well for that purpose. So the SDR and cables might be good and I'll remake the dipole next.

Could you have a look how your waterfall compares to mine? I seem to get a weak signal, and sometimes it decodes, but I feel there is something missing. This morning, I also had the automatic thing connecting when the satellite passed, but only grey in the decoded picture. At the moment I think, maybe my signal is too weak?

Idea is good, but take a suitable diode, not one of these toys. At 0.8V and 10A, the diode needs to dissipate 8W. Put this into your MC4 connector and you get a nice ignition device to burn down your whole installation.

Before this dish, what antenna and software did you use for the previous pictures? I played around with this stuff some months ago, IIRC the frequency was around 160MHz ? , made only a simple dipole but could not get any good reception with the SDR.

I would not really call these reductions cut throat. In china, they can sell the BYD seagull for around 10k$, and I m sure they dont sell at a loss. The Dolphin which is similar, was 799kB at the beginning, and now they are producing in Thailand. The cost of labour in TH might be even cheaper than in China. Therefore reducing the car to 500k, would seem to me just normal price. Its not that they are making losses. I m waiting for an electric pickup reasonably priced. The Riddara 6 entry level model at 900k is still way above ICE pickups and that cheap model can only go 300km or so. Electric should be cheaper to produce than ICE with 10 000 moving parts only in the motor. And therefore the cars should also be much cheaper.

No the shark is too expensive for me and I dont want plugin hybrid for the same reasons KhunLa explained.

Wife says, she saw somewhere that BYD announced a full electric pickup in TH for the end of the year. Did anyone see this? I m reluctant to buy the riddara rd6 seeing the issues Neta V owners have now. Neta even had dealerships, but very little repair centers and no spare parts. Geely seems in the same situation to me. Therefore my hope for something affordable pickup size from BYD.

If you see the prices in China for exactly the same vehicles, and if they are produced in TH, then there is still room for nice discounts.
