  • Regarding SDR, there’s a variety of software for different purposes, but some good starting points I can think of are:

    Gqrx is great for receiving and listening. Other options are available.

    GNU Radio was used for making Gqrx. Maybe you could make something with it too? According to themselves, it is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in research, industry, academia, government, and hobbyist environments to support both wireless communications research and real-world radio systems.

    There are also other applications made for encoding and decoding various digital modes, just like the SSTV apps for Android, but I don’t remember their names right now. I remember that some of them work by decoding the demodulated audio (e.g. audio output from Gqrx or a signal from an external source) so for some of those you will probably need some audio routing software, as these are not made for the receiving or transmitting radio but just for encoding/decoding digital modes to/from audio.

    Since I’ve only had receivers, I’m unsure what the coolest software for modulation and transmission is, but here’s at least something to get you started with SDR reception.


  • While you’re looking for a radio and waiting for it to arrive, you could prepare yourself for further exploration of SSTV modes through these two apps on F-Droid:

    SSTV Encoder

    Robot36

    Running both at the same time, you can encode, transmit (as audio), receive and decode on the same device (or on two devices that can hear each other). You could also feed the audio output into the radio you’re getting and transmit it over the air, or receive and decode other SSTV transmissions. When testing it over audio on local device(s), it’s always good fun to distort the images (as if they weren’t distorted enough already) by making weird noises over the audio signal, where different frequencies and amplitudes of course will result in different colors and patterns, depending on the mode etc.

    If you’re into computers, you could even consider buying some SDR (Software Defined Radio) transceiver instead/too. It’s basically a radio tuner you connect through USB and encode/decode through software, so you’ll be able to encode and transmit from your devices, and to receive and apply DSP, decode digital modes, listen, record or whatever you want to do with it. Note that some (like RTL-SDR) can only receive but not transmit. I believe the HackRF does both, but it’s been a while since I looked into it, and I’ve only ever had RTL-SDR-based receivers. There’s a lot to look into here!

    Btw, have you considered searching for other local or competing options instead of going straight to Amazon for a ham radio – maybe even something used that does the job? I’m pretty sure there’s plenty of used ham equipment to find on online second-hand marketplaces, ham radio groups on facebook, something related to the national member society representing your country at IARU or ask the members of some local ham radio club?

    I’ll catch your SSTV transmission or something equally as cool some day, yo!









  • Thank you. I do have Arcticons Dark installed from F-Droid (it’s just called Arcticons there, it seems, while the other editions have their full names), and it’s the latest F-Droid release of it from 3 weeks ago. I already assumed it would work like you described, but only the “Breezy Weather” and “Pixel” icon packs are showing up there.

    I’m unsure what could cause this, but some possibilities I can think of are:

    🤏 Differences between F-Droid, Github, Accrescent and Google Play releases?

    ✋GrapheneOS system security restrictions limiting the scopes of the apps?

    If you (or anyone else reading this) happen to know anything that could lead to a solution, I’m all ears!


  • Then what you need is a VPN that supports port forwarding. There are very few, but I bet you can find a thread somewhere on Lemmy discussing the options you have. Then, if I’m not mistaken, you still need to know/set the port number in your torrent client and config the router correctly, probably through its admin site which you’ll find on the router’s IP in the browser. If you don’t know the login (and admin/admin doesn’t work) you can find the default credentials by searching the web for your router model number + admin login. When logged in, you can set new admin login credentials if you don’t want other users of your local network to be able to access or change the config settings.



  • Check the open port number of your torrent client – which should also be set in your router’s port forwarding or firewall config (alternatively enable UPnP in the router config to let it handle such things for you).

    You can use a utility like CanYouSeeMe.org to check if it’s correctly configured.

    EDIT If you can’t make it work, you might be behind double NAT, sharing varying IPs with multiple other of the ISP’s customers at once. In that case, you’ll need to find one of the few trustworthy VPN providers that support port forwarding to get connectable, as it’s called, and be able to connect to all peers no matter if they’re connectable or not. Alternatively, rent a connectable seedbox in the cloud.





  • r/TV_NCA on reddit has such things… Though, that one is a members-only subreddit, so you will need a reddit account to get approved by a mod of the sub. I read somewhere that they’ll accept most membership requests - but only if the account has some karma…

    The private torrent tracker TVCUK has it too.

    I also saw a filehost link posted on a private Discord server - which is a different annoying obstacle in itself, and I’m not sure if I should share more details about that server in a public comment like this, though it is really great for UK, AU, NZ stuff. Though, if you can join r/TV_NCA a lot of the same stuff is available there too.

    Other related public subreddits now we’re at it:

    • r/TellyBum2 for UK stuff (but low activity)
    • r/DownUnderTV and r/RooTV for AU/NZ stuff
    • r/panelshow for various panelshows of the world but mainly UK ones
    • r/notpanelshow for content featuring UK panelshow regulars but isn’t a panelshow
