nice project! it would be interesting to expand the project and the code by adding other sensors
@radioastronomy20012 ай бұрын
The original project had a web server. I was thinking about adding a local display. I don't have access to other sensors. I am sure someone can run with this and add support.

Excellent contribution, could you upload a copy of your ini file with raspberry w please?
@radioastronomy20012 ай бұрын
Sure I will. I just wanted to see who will ask first. Many people have seen this video and nobody asked for the file. I will do it soon.

Thank you very much, I was able to download the file and put it on my rasberry pico w, I edited the parameters indicated as my callsign, password, longitude and latitude, ssid and password, everything is fine on the arduino monitor, I see that it makes the connection but I can't see myself on the APRS map

A very comprehensive explanation! Thank you. I just want to run SDR Connect exclusively from my Pi4. I use it to see how active the ham bands are before firing up my rig in the garage. Can I cut and paste the commands you used to get a more limited functionality. Ray VE2WEW thanks
@radioastronomy20013 ай бұрын
Thank you for your interest and comment. I have not included any commands in the comment or description section. You can type them blindly, based on what you see in the video and it should work. There is very little customization done and a lot of limitations. It would be cool to run SDR connect as a service so it starts automatically after the reboot without the need to login. Good luck with your project.

hello my friend, I've been building my own J-Pole antenna for months. I build it with pasture fence wire in Germany, we say Weidezaundraht. You can buy 400 meters/1312 feet in 1.8mm/1/16 inch thickness for around 30€/32$. The wire is made of aluminum and it's cheap and quick to build for many antennas, but it has one problem: it's not stable for long antennas and needs a support like a fiberglass pole or something, i hope, the information can help you 73 DO4NRW Andreas from Germany

Cute square loop! How do you have calculated the coupling gamma match? What are the dimensions of the dipole and what kind of balun have you used? Greetings.
@radioastronomy20016 ай бұрын
Thank you for your question. The gamma match has been sized experimentally. Originally, the antenna has been "designed" for 6m, but then I have added some capacitors to bring it down to 10/11m. The dipole is a full size self-supporting antenna made of aluminum 3/8in Tile Edge (I do not remember exact dimensions but it was long and sturdy enough) I got some leftovers after bathroom renovation. I just have several turns of cable, the "ugly balun" to work with it. It was done good 5 (or more) years ago and I have not documented it well. The dipole works OK and have used it many times to talk on our local 10m net.

@@radioastronomy2001 Tile edge... How interesting material! Do you mean full size dipole like a half wave 6m dipole (3m long)?
@radioastronomy20016 ай бұрын
@@DJMotavirust Each piece was about 2.5m long (8feet) Ideal size for the 10m dipole. I had to trim a bit to tune it. (And YES I have another one for 6m just above it. Made from different aluminum scrap pieces) All this is held together, using some small screws, by a plastic cutting board.

Well done, Tom. I think we need to do more field testing with the small loop. I believe the results will be surprisingly good with digital modes. 73 from VE3TWM!

Thank you. After about 6 hours of listening the loop received signals from all major continents. I am quite pleased with the results.

how do you the transfo? any details?
@radioastronomy20016 ай бұрын
Thank you for your question. 4 turns primary and 4 turns secondary. You start from one side and you end up with two ends sticking out. Then you wind the secondary side starting from the other end of the binocular core. It takes a minute, so even if you have to start over and do again it is not a problem. (Actually the both sides are identical, 4 turns each) The ferrite core does not have to be binocular. I am sure you can use a toroidal core too.
