Add deponent radio

what's going on guys kn4 mkb billy here and today we are talking about some more digital ham radio so last year you know that we did the winmore protocol over win link to send emails back and forth well as of the 10th of july 2020 that is gone and i didn't know it until somebody actually commented on the video and told me it didn't work so the new protocol that we're going to be using is called rdop the amateur radio digital open protocol it has been in production since 2015. so it is pretty much made to be a replacement for winmore and other sound card type packet packet systems so it's going to be more it's going to be faster it's going to be more robust and this is all around better performing i've got to try it out here for a little bit and from what i can tell it does establish connections quite a bit easier than win more so i'm pretty excited about getting into this and showing you guys if you haven't watched my sound card video about automatic level control i do recommend you check that out if you don't have a ham radio that has a built-in sound card it's really helpful for these types of thing make sure you get your audio levels right and i do recommend that you turn up your radio just a little bit to hear yourself while you do this or actually hear the other station so you make sure you're making the connection without further ado let's go and get into it we're not going to start start from very scratch i'm not going to show you the details of how to set up wind link because it's relatively easy so the first thing you need to do is actually go download windley and let's go ahead and just roll over to the computer here so you guys can see what i'm doing so the link the link for winlink will be down below but basically you just need to go on the website hit the download button and just download the program all right so user programs and uh you're gonna download winlink express right so you're gonna install that and once you do you're going to come up with a registration screen and that's the first thing you need to do or the second thing you need to do is basically just register your account and that's going to get you an email address that you can use with the winlink system and this gets you into the system there's not much to see here it's a basic email client so up here you have your settings some different settings i don't really mess around with it too much to be honest you can create new messages and reply to others here you can uh see your attachments that you've received from other people and what we're paying attention to here for right now is going to be open session so uh and of course you have your inbox and your red items and outbox and all that fun stuff over here and you have your incoming emails it's basic email if you've ever used the email before so the first thing i'm going to show you is actually the telnet so telnet win link is literally just ip right so you're just literally connecting to a server over your internet assuming you have it and it's just a quick way to get your emails or send out emails if you have them and you have access to the internet but that's not the point of win link is it so the point of win link if you don't know already is basically to send radio uh send email over hf so or any other message really so i want to show you guys how to set up rdof which is a new protocol because we need to replace the old video right so it's pretty self-explanatory and it's basically the same system so you're just going to choose this drop down here and choose art off right and you're going to hit open session and it's going to pop up this window here and we're going to need to configure a little bit of settings and like i said before make sure you know how to use the sound card [Music] it's better to get those basics out of the way now than to try to deal with uh what will happen later if you don't so the first thing you'll want to do once you actually open up the rdof when link section is go to your settings and go to your tnt setup and here you're going to be inputting your capture device for your your microphone and your playback device for your speaker which is our data in and out for a radio right the drive level is actually going to be your power level on your radio and this is something that you may have to play around with i tend to be between 50 and 100 because uh 100 will make my alc kick in and 50 is this a good level for me and that's something you'll have to play around with too so once you start transmitting pay attention to your radio make sure you're not over driving your radio and make sure you're transmitting out of power that you want to and not under right so all these things of course with the sound card have to be played around with just a little bit to get it working the way you want it to so the next thing you want to do is go to radio setup now you don't actually need a push to talk line to get this running but i really advise that you do or compromise on and unfortunately right now push to talk is one of those right so i keep mine on manual none of this stuff really applies to me because i'm not using any type of serial port or a push to talk but if you guys have that i really or you can get it i really suggest you do that because it's really going to help your performance and it's gonna help you not interfere with other people while you're transmitting if other sounds decide to come through your speaker so once you have that set up you can do a transmit level test and you can look at your radio but my myself i have found that it is not the same as when i'm connecting other people so i watch when i connect to other people and then i can tell now whenever you set up your win link it's going to ask you for your grid square and what that's used for is actually finding the best stations to connect to so if you hit your channel selection here it's going to automatically download the channel selection from the internet if available if you don't have internet if you can connect to one of these without getting the list then you can actually download that list but i have internet now so it's downloaded the list for me and it shows the most you can organize it by the most uh highest probability of success making that connection so i found that i i had to go through a few of these and try them out right and and that's another thing you usually have to play with with these things you might even if everything's green and it looks good to go that doesn't necessarily mean that you're going to have a good connection because they could be in the right spot but not the right polarization antenna they could be down in the valley somewhere you never know right so sometimes you have to play with these things and i found this connection right here usually works pretty well for me so once you find one or you want to experiment with one what you'll do is click on it right and it's going to load your settings here it's going to call the call sign the center frequency the dial frequency bearing and quality so what we want our radio set to if you don't have that cat control set up is your dial frequency right so my radio i'm looking at it it's at 7.064.50 that's correct another thing that you want to make sure is that you're in some type of data mode if not you're at least in upper sideband because all these data modes around this region are in usb those are the two main factors that you need to make sure of here you also want to turn off any type of weird noise cancelization noise blanking um you you want all of that in there because some of these digital modes uh it sounds like noise because it's not voiced to some of these program these programs that filter some of that stuff out so just disable all your noise blanking and and make sure that you don't have any weird dsp stuff going on there so once you have that done the next thing you want to do is just try to establish the connection so to do that you'll just simply click start and you you guys may hear my radio clicking it clicks when it starts to transmit um but my radio is going to transmit here i'm going to turn it up to see if i can start hearing it and you're also going to see a waterfall here and this waterfall actually show you the signals too those blanks are when i'm transmitting the noise here is the radios just noise coming through i've noticed with this node it takes a minute there we go so you guys probably see it on the screen here this is actually the signal coming in i'm going to turn up the radio and see if you guys can hear this okay so actually i have some noise cancelization going on in my audio recording and i think it's completely blanking everything out i guess that's a good thing for me but not so much for you guys on the video yeah it doesn't look like the audio is coming through that's fine so you're going to see an update here of your current session and it's just going to populate with information telling you what is going on right so it tells me i've connected it shows my bearing sometimes shows distance it shows how much time you have left on this current connection to this node uh and all while this is going on you're still going to get that waterfall display to kind of show your connection quality and get an idea what it looks like i like to like i said i like to have my radio turned up just a little bit so i can hear it because then i i get a good idea of the the station's strength if it's weak and fading out then i know that maybe i should look for another node all right so not much happened there so now we're going to go back and actually send a message out and we're going to send a message to my winlink email so to do a new message we're just going to hit new message here and we're going to send this to kn4 mkb at the modern am dot com subject we're just going to be test email and input testing the winlink email system right nice and simple and now we're going to post this to the outbox right because we got to open sessions before we can actually send messages we're not using the internet so that's in our outbox and as soon as we establish a connection that's gonna go out so once we establish this connection it should send our email and we should receive the email i sent to myself so i'm gonna go ahead and start this session and we should see a lot more activity on the screen here and we'll also see a lot more activity with a little waterfall display once it gets up and running all right so there's our signal coming in and once again if you do have a push-to-talk system it's going to be a lot easier on you uh it's going to it's just going to be a lot more efficient so i really suggest you set that up if you don't have one already that's something i really need to do oh well this side here is actually your email you guys can't see it because my webcam came on but this is our email that i just sent myself testing the wind link system this message was sent from amateur radio account it adds this on just to make sure if your test you're sending email to somebody that doesn't know any better they know that uh there's a little bit more rules and regulations they need to watch out for but real quick i also want to show you guys the grid file request so this is kind of cool too if you live in a remote region you can actually request weather data weather maps in the form of a grid file you also need software to run that i'm using zgrib and i'll put a download link for that down below too but i'm just going to show you guys a quick example of that in action as well so you'll request a grip file and you're going to select the region you're going to kind of select what you want to see so i'm going to say rain waves and wind for the next uh one day in one hour so i'm going to hit post request and just like an email it's going to go in my out box right and so i'm going to make that connection to rdop and it's going to send this request out to the servers right that handle this stuff and that's step one so the servers are going to get this request and they're going to compile that data for me and then they're going to send it back to my win uh my winlink email address with the group file that we can open this could be useful if you're on out and see or something you actually don't have access to internet but you would like to know what the weather is so you can send the request for these files in certain regions to see if it's going to rain over the next few days and you'll be able to open that up and check that thing out so that's a pretty neat little feature too if you're if you're living remotely and you're actually using this to access the internet and outside information but i'm just going to show you guys a real quick demo of that all right so now that that email is sent which is just a request for this grid file now we're going to reconnect to the winlink node and receive that group file and that could take a little while because this is like dial up speeds right it's really slow but it's over radio it's over hf and it could be thousands of miles away which is really neat so uh we're gonna go ahead and reconnect to this if the message is ready we're gonna know it's gonna let us know uh and it's gonna take a little while to receive so i will see you guys when we get done receiving that file and we're going to open it up and just check it out all right so we have received our email and i'm just going to go over back to the inbox and as you can see i have one new message that's under red i'm going to double click that to open it and this is just got some information about the coordinates and uh some of the the stuff that we requested that's encoded in the message and so i'm going to hit view attachments and this is our grid file i'm actually going to save this to my desktop and i'm going to open that zygrib zy grip once again the download link is going to be below in this program is this going to allow us to open that file and visually see what data is in there so i'm going to open this up and as you can see we have like the wind forecast and we can actually drag this over over time to see how things change and that's just a really really cool little feature of the program but as for wind link there's not much more to it i hope you guys enjoyed the video if you did make sure you subscribe to the channel make sure you like the video and comment down below what you think anyways 73 to you thanks for
