Cheapest decent solution to connect/convert amiga 500+ scart signal to hdmi?
I built a ESP8266 controlled GBS8200 as main scan converter. https://github.com/ramapcsx2/gbs-control You can get a GBS8200 for about 24$ + shipping and an ESP8266 doesn't cost much. And also it just needs basic solder skills. Not really complicated to build. Then you have a great VGA output. And that you can convert to HDMI with a cheap VGA-HDMI adapter. I personally use an old Eizo 5:4 VGA Monitor because of the aspect ratio but sometimes I do actually connect it to HDMI to record things in OBS.

Upscaling ITU BT.656 480i NTSC Video to SVGA 800x600
Try searching for GBS-CONTROL. You should probably start looking here: https://github.com/ramapcsx2/gbs-control

I just got this cruisn usa board from ebay and it seems to be giving an error code and no video. Anyone familiar with this?
Some games also require you to move the sync signal over to the next pin, some games require sync signal to both pins at once. It can take some fiddling for a few games but I've always gotten it working eventually. It could help to also go ahead and upgrade the board with GBS control. I have my Rush setup that way and it's pretty handy being able to adjust the picture wirelessly with my phone.

Best N64 to HDMI converter?
In my opinion GBS-Control. https://github.com/ramapcsx2/gbs-control

Can some one with experience with GBS Control give me a hand? I can’t access the web interface
Try some of the other URLs after connecting to the local wifi. https://github.com/ramapcsx2/gbs-control/wiki/Software-Setup
- Just got my GBSControl in! Best picture clarity I've seen out of the Saturn thus far using RGBS cables on a modern flat panel.

Best/Budget Friendly CGA converter.
Arcade "CGA" isn't real CGA, it's just analog 15 kHz RGB. You'd have to use something like this to convert the CGA from your computer into analog RGB if you want to feed it into one of those GBS-8200 boards. They're not very good unless you modify them anyway. I use an OSSC to convert analog RGB to HDMI, but that's more expensive.

I build a GBS-Control to use with my new Saturn. It works great!
After a bit of research, I almost pre-ordered a RAD2X HDMI cable, but that would likely be around $85 after shipping, and wouldn't get here for a while. Also, it only works with the Saturn, while I was hoping to find a solution that will work with other retro consoles. Luckily, I came across this video by Voultar showing how to build a GBS-Control.

Ps1 to pc monitor
If you know how to wield a soldering iron then a GBS-8200 plus gbs-control firmware does a good job too for a much lower price, but that does get pretty technical.

Ask HN: What weird technical scene are you fond/part of?
- Sometimes the web UI won't have 1280x960 checked, even if it's outputting a 960p signal. I don't know if this is connected to the vertical shift bug, or if .
Again I'd have to dig into the GBS-C source code to find out why mode changing behaves oddly. There will be a lot of learning to do, understand the software state and chip registers and how they correlate to profile settings and input/output behavior. I suppose I could file a bug at https://github.com/ramapcsx2/gbs-control/issues, but somehow I feel reluctant to do so, partly because I didn't fully understand the setup and don't know if many of these bugs wouldn't happen on a VGA CRT, partly just learned helplessness and not knowing if my bug report is detailed enough or will be ignored or attacked, partly because I'd prefer to chat with the developers in Discord/Matrix outside of a higher-stakes formal bug report or a forum I've never posted at before.

multi_rx,py example for decoding multiple voice channels on single rtlsdr
looks like it may not be able to do what I want it to do according to this. https://github.com/boatbod/op25/issues/184

How can we convert a DMR signal into clear voice by RTL_SDR?
I have no experience with DMR myself, but my understanding is that the Boatbod fork of OP25 has experimental DMR support, and I believe SDRTrunk software does, too.

Ask HN: What weird technical scene are you fond/part of?
Using OP25[1] with RTL-SDR dongles to implement scanners for trunking P25 radio systems on a computer. And as a sidebar to that, listening in on geographically remote public safety radio systems using Broadcastify[2]. It's basically the old "radio scanner" culture, but taken online and distributed worldwide. People listen to all sorts of stuff, but given my background as a former firefighter and former 911 dispatcher, my main interest is listening to public safety dispatch stuff.
That said, another commenter below mentioned modern "phreaking" and how it's become more radio centric... and while I won't admit to doing anything illegal, let's just say that there's some interesting stuff you can do / look at / listen to these days, especially with ubiquitous and inexpensive SDR hardware and related resources. See the recent story about the KrakenSDR passive radar stuff, and some of the papers that are out there about P25 security flaws, some of the automobile hacking stuff that's RF based, etc., etc. There's a fascinating world out there buzzing around on invisible electromagnetic fields... and you can tap into it with a $30 dongle and a Raspberry Pi (or your PC).

Is this encryption or frequency hopping or just not FM modulation? Not law enforcement, just a school they use Motorola handhelds.
If it's P25 Phase I or Phase II then SDRTrunk might work. boatbod's op25 might be another option, but more complicated to set up.

Using a Raspberry Pi without a GUI to stream scanner audio to a phone
I don't have a full guide for you, but I use https://github.com/boatbod/op25 for receiving and decoding P25 Phase 1 digital signals on the command line.

How can I hear the Franconia, VA (Fairfax Co) Police, Fire, EMS scans? Unsure if there is a specific open mhz link for them. Thanks!
If you are handy with Linux you can use an RTL-SDR and OP25 on a Raspberry Pi or really any PC. This is the page for the Fairfax trunked system https://www.radioreference.com/apps/db/?sid=6957. Any talkgroup with mode D can be listened to, mode DE is encrypted. If you want I already have config files made up for the police dispatch and fire/ems dispatch channels.
