 Okay, welcome, and again, this is part of a series on sending files and information from your computer to other devices using audible tones. And we're gonna do this through the airwaves and stuff. And again, this is part of a series. There are gonna be lots of videos following up on this. We already watched the previous one on doing Morris code on your computer. If you haven't checked that out, be sure to check out the full playlist. There should be a link in the description, and hopefully at the end of this video, if I remember to put it there. Now, as I stated in the previous video, Morris code is an option. Oh, but it's super slow. So the next option I looked into is something that I used to play around with years ago called PSK31, which there's lots of different similar things to PSK31. PSK31 is just the format that I'm used to working in. But the program I used to use, which is called GPSK31, no longer seems to be in the repositories, and it was kind of outdated at the time of making it as far as how it worked with the audio devices on my computer. I had to start up basically virtual sound systems to get it to work, but it worked fine. But let's go ahead and look at what is available in the repositories. Again, I'm running Debian here. I'm gonna do aptitude, and I'm just gonna search for PSK and see what comes up. And here you can see we get a few different programs. You can see right here that I have three installed. And we're just gonna play around with the first one today. They're all kind of similar, but Lynn PSK. So I'm gonna start that up. And Raymay, if I click this Transmit Receive button, it's gonna tell me that the device is not available. And it does not seem to save my settings. I gotta go into Generals. Actually, there was a Save Settings button there, I just realized. But if you go into Settings, General Settings, we're gonna change this to whatever your audio card is. I'm gonna set this to my internal audio card here for both the input and output. And I'm gonna click OK. At this point, I can go ahead and click this Transmit Receive button. And I'm now listening and transmitting. And up here, if I had audio coming in, I'd be receiving it. And down here, I'm gonna type what I want to go out. And you can see it is picking up my microphones, picking up some audio that it's trying to decode, but it's not actual tones. So you'll get that occasionally when you're just recording from an open mic. But let me go ahead here and I'm gonna start typing. And I click Transmit. And I can keep typing. So as you can see, it's transmitting. And it's not just using dots and dashes like Morse code, it's actually using different frequencies to send different messages, which is a lot faster. And I like PSK31. And there's a lot of programs all similar to this, and they're all geared towards people with ham radios and sending out, you know, communicating with other people. Let me go ahead and stop this here. And I'll tell you what, they're very easy to use once you open them up, you know, at least getting the little bit going. There's a lot of options in here that I haven't even played with. And they all have similar options. I'm gonna do, I'm gonna exit out of this. The problem with PSK31 and other similar, I'm not sure the word I'm looking for, formats of sending data like that, for the most part, are all GUI interfaces. I could not find a shell, a command prompt application for PSK31, which kind of makes it useless to me for what I'm trying to do, because I'm trying to receive the information and send it from other applications and then dump it into other files that programs can pull from. So although this is a great way to communicate, if you need to, it does not work for my project of having input go out and then being manipulated into its own little GUI or some sort of format output or even sending commands to another machine. I need it to be a shell application, not a GUI application. If anyone knows this of a PSK31 program that's available in the repositories, I don't, I have no need to go out of the default repositories for Debian. I would love to know about it. Even if it's not in repositories, tell me about it, I'll check it out. But I try to stick to what's in the repositories. And again, there's a few of these programs and that's just ones that have PSK31 and the title. There's other programs out there that it may not be in the title here. But again, so many of these with GUI interfaces, I'm surprised that I can't find one that is just a shell command because you would think it'd be simpler. But I found something similar that we're looking at in the next video that does very similar. I'm not sure as far as speed, how well it works, but it's very similar and it is a shell command. It is in the repositories. So I thank you for watching this. Again, check out these PSK31 applications. There's a few of them. It's a fun way to type and send information, communicate with other people through audible tones. I thank you for watching. Be sure to check out the full playlist. There should be a link in the description of the video and hopefully at the end of this video. And there's more videos coming out later this week. So if you're going through the playlist and a video is not available, it will be in a couple of days. So, and if you're a Patreon supporter, you've already gotten these videos unless you're watching it. Yeah, Patreon supporters get download videos if you're in that tier of support.
