RadioMail 2.0 Best Path Prediction

What is the best gateway to connect to? A new prediction score in Radio Mail 2.0 helps you answer that. [whistling music] Now, by default, when you start a session and you select the gateway, it will open up the best path prediction window, and you see all the remote station that you can connect to ranked by score based on the prediction of your ability to connect to them. So you can scroll around and select the one you're interested. You can also filter down that list. So you can open the filter, change the mode, change the band, and basically narrow down the list based on your current capabilities. Maybe you don't have a particular antenna that day, and you don't want to see any station on that band. Once you change those parameter, the list will, uh, recompute and resort automatically. All of that is done locally on your device. And there are a couple of assumption built in, uh, in term of radio power and the noise floor that you have around you, and you can change those at the top. So if you say increase your power of your station, now you'll see the score going up. So obviously, green means you're more likely to connect, uh, and as you go down the list, um, you're less likely to be able to establish a connection. Uh, also note that the, uh, station that are NVIS are identified as such, so that you can also deploy your antenna in a way that will give you the most, um, likely-likelihood to reach those station. Um, with HF, propagation depends on the time of the day, so you can actually change the time, uh, in the future over twenty-four hours to actually see how the propagation change over time and perhaps determine a better window for you to be able to connect to a particular station. Um, so that changes, uh, quite a lot. So it's actually pretty fun to play with it and sort of see when your communication window should occur to be able to reach some particular station. Now, let's take a look at VHF/UHF station. Let's switch to packet. And for this mode, in this case, the only factor is the distance of the station to your location. So the prediction use the location known of your device as well as the station and will rank them accordingly based on your ability to, um, reach it. Now, in addition to that, both model also incorporate successful or failed attempt to connect to station to influence the score. So every session when it's completed, the information is aggregated anonymously and is being used to actually weigh, um, the station based on, on those, uh, recent report. And if you look here, the fourth station here, WH6AZ-10, even though it's very close, it's one mile, it's in my lab here, it has a low score because it's the station I use constantly to test, and therefore, there are a lot of failures, um, that occur with that station. And therefore, the success rate is determined to be lower because there's been a lot of failed connection that have been reported against that particular station. In addition to the best path prediction, Radio Mail still has the notion of favorite, like the previous version of Radio Mail. So you can navigate to your favorite, and any station that you use frequently will be found here, and you can, uh, filter them by mode and band, so you can easily find them and do a quick connect. Um, you... This can be both station that are coming from the Winlink directory, but also custom station you may have added will re- be reflected here. So to favorite your station, you go into the dir-directory itself, and you will see all the station with a star are favorite. You can filter them. The filter here is similar to what you find in best path prediction. Actually, the settings will, uh, carry over, except here you have a few more, um, filter you can toggle. You can, um, filter by origin if it's a published station from Winlink or if it's something custom you've added, and you can toggle those to navigate your directory. So let's re-add the HF, uh, mode here so we can have all the station available. And in the dir-directory, the station will, um, be combined with all the channel available, like in the previous version of, uh, Radio Mail. So if you select a particular station, let's say H six, uh, H seven L here, you see a, a map with the location and all the channel are basically the band, the frequency, the mode that this station exposes. So you can see everything at one glance. Uh, you can favorite if you want it, and you can get a sense of the capabilities of what is, um, nearby you. You can also quickly search the directory. If you know a station or you wanna look at certain call sign, you just tap it and it will filter the list down to, uh, your entries here. And once you've found the station, if it's the one you had in mind, you can look at its location, look at the channel, add it to favorite, and do that very quickly. If you want to add a custom station, you go into your favorite. You can look at the custom station there. Uh, and if you, um, create a custom station and you actually enter a grid square for it, it will also show it on the map, and it will get included in the best path prediction because now the application knows where this custom station is located. When you enter a custom station, you can name it. You can create an alias. And like previous version of Radio Mail, you can also set up a connection script. If it's a packet station, you can turn it on and then describe what command to execute. If you connect to a node and want to establish connection, you can do it so here. With the best path prediction feature in Radio Mail 2.0, you can now start with the station that's most likely to answer. Mahalo and 73.
