namlosh posted:Hey thread! So the genuine RTL-SDR is perpetually out of stock so I need a recommendation on what to get to dip my toe into SDR stuff. For watching planes I just use https://globe.adsbexchange.com/ so I don't have to spend one of my SDRs on it. Most of TX is on trunked P25 systems with some counties being completely encrypted. Check out https://www.radioreference.com/db/browse/stid/48 to get an idea of what exists in your area. I have a few of the RTLs that Jonny linked and they work just fine for most of the stuff you've listed.

wolrah posted:Like a lot of hobbies, there is no right way to do amateur radio. There are of course some wrong ways, like transmitting where you're not supposed to or loving with other users of the spectrum, but as long as you're not doing those kinds of things then do what makes you happy. If you're enjoying yourself and maybe occasionally learning something you're probably doing pretty well. Ahem. Reminder, we use DMR to hold a net bi-weekly.

Yeah, it will come to life Tue/Fri 9p eastern. Generally the script is ran through in like 10 minutes and a lot of times we'll rag chew afterwards for a bit.

Since we are talking about securing janky antenna structures, feel this is a good point to mention that tripods designed for holding up speakers are great. They're designed to mitigate top heavy loads, and can easily be attached to with gear that you would use elsewhere.

evelyn87 posted:I've taken an interest into understanding radio. I volunteer at a local fire department and historically they've had their own VHF/UHF "network" with repeaters they own. I'm an IT person so I never took time to understand how all of it works, I just threw some of their gear on their own vlan's and routed them across our IP network, what was actually being sent I have no idea and didn't really care to figure it out. I don't think there is any frequency you could use to do this that wouldn't require every member taking part of it to be a license amateur. Edit: Well, you COULD use 802.11 but that's really more in scope of the "IT aspect" on what you're setting up as a deliverable and ventures into this realm via "how do I properly distribute the signal" Double Edit: What you're talking about is a WISP really more than using RF for sending messages al-la APRS/wspr/wsjx/etc. drunk mutt fucked around with this message at 23:51 on Mar 1, 2023 |

doomisland posted:I'm in my "I should get a HAM license phase" and was looking at antennae and from my situation of being in a town house with window screens that don't open and no balcony a loop antennae seems to be the best option in a theoretical set up. Is there a go to guide for building one? Guessing with the "should get licensed" statement, are you planning to start out and just get tech? If so, I'd just look at getting an n9tax https://n9taxlabs.com/shop and hang that somewhere. I have one literally hanging off the side of my desk and it "works".

M_Gargantua posted:Also what is the obscure english word for getting a radio licence and then immediately wanting to go ham on building a radio tower in the middle of my rural forest. There are probably like 400 tower sections in good state available to you second hand. We had a lot of silent keys the last 3 years, and I know at least down here, you can get pre-built tower sections for pennies to their value.

Achmed Jones posted:me too but then i got it and put it on a shelf and didn't plug it in Why would it be any more difficult than any other device? Honestly, the rtl-sdr hardware is what I prefer because of the simplicity of getting it working on the host system in a way that I can taint a node and have something like op25 access the hardware. If you want to get super fancy, you can setup udev rules on the host system so that you don't even require privileged containers! Bottom line is, if you can get the hardware operating on the host system you can get it operable in a containerized slice of said system.

I guess I'm missing something here, why does this matter inside of a container? This is crap that has to be done on the host system and once that's setup, provide access to those resources inside of the container. There are quick and easy ways of doing this that aren't very secure, but it'll work.

Achmed Jones posted:most people running a fleet of containers for their silly personal projects aren't doing it on windows hosts. you can't run windows containers on linux hosts. someone has to create and share the container in the first place. the problem isn't with mounting a usb device in a container or dropping a binary inside a container, those are trivial. it's the whole "windows only" thing that's an issue, and that issue basically kills the containerization stuff before it gets off the ground That makes sense, when I was reading through the github that I found on it it didn't seem like it was completely restricted to using the pre-built dll and that was just the artifact they offered up. Looked like with some work one could get it working within other build ecosystems. Don't doubt I am wrong there as I skimmed that repo.

Coxswain Balls posted:I'm trying to view the hydrogen line by following this paper as a base, and so far I've got the thing bashed together at least. It was snowing today so I couldn't set it up outside, but it's working well enough to triangulate some spurious emissions on 1419 MHz somewhere on campus. If I want to fine tune things more it sounds like I need a VNA, but I'm not sure which one I should get. NooElec has the NanoVNA H4 and the NanoVNA v2 SAA2 for the same price ($163 CAD), and while it seems like I should just go with the latter because it has a higher frequency range, I'm sure there must be more to it than that which I'm missing. It's a tool that analyzes, if they seem interested just ask as the worst is they just nope out. As far as the NanoVNA, it is a nifty lil tool that plays nicely for things like this (just use the software instead of the builtin interface) so that also is an option. Don't know if there are cheaper versions that might work and am now starting to wonder if my "NanoVNA" was even done by Nooelec.
