Power Genius XL Utility v2. March edited June 2 in Third-Party Software. It only took me maybe 20 minutes to get the software installed and running. March edited March Thanks Roger, I have not tried that yet.Digimode Automatic Propagation Reporter This started out as a project to automatically gather reception records of digimode activity and then make those records available in near realtime to interested parties — typically the amateur who initiated the communication.

The way that it works is that many amateurs will run a client that will monitor received traffic for callsigns the pattern 'de callsign callsign' and, when seen, will report this fact. This is of interest to the amateur who transmitted adn they will be able to see where their signal was received.

The pattern chosen is typically part of a standard CQ call. The duplicate check is to make sure that the callsign is not corrupted. The rules for protocols like FT8 are different as the callsigns are protected by error correction.

You do still need to call CQ in order for your signal to be reported. The way that this would be used is that an amateur would call CQ and could then within a few minutes see where his signal was received. It will also provide an archive of reception records that can be used for research purposes. There is a map display of this information. There also a page of statistics about the project. If this is interesting to you, then please contact me at the email address below to see if there is a client for your digital mode decoding application, or you can contact the author of your package directly, and point him at this page.

Note: This system does not transmit any signals over the air, it just makes use of existing signals that are being transmitted by people calling CQ.

This approach is different to some other propagation reporting tools, and has the advantage that adding more monitoring stations provides better coverage without consuming any bandwidth. Also, you don't need to have an amateur radio license to participate.

All that is needed is an antenna, a radio and a computer, and you can start monitoring. Current Uses Many of the monitoring stations like to use this for bragging rights. It is also interesting to see how long it takes to spot different countries. A well placed station with a decent antenna can do this within a week of monitoring, but the best systems can do it within a single day.

It includes integration with PSK reporter. To enable reporting, you need to enter the following information into the settings or preferences panel. On the general tab, you should enter your callsign and your locator. Enter at least a six character locator as it marks your location on the map with more accuracy.

On the frequencies tab, you should specify your antenna on a per-band basis. This makes it a painless operation to install and use. There are typically over active monitors during the day, mostly in North America and Europe, which means that your call is likely to be heard.

More monitors from other parts of the world would be much appreciated. This will open a dialog box, and you just check the 'send updates' checkbox, and you are done.

Now, whenever the SuperBrowser detects a callsign, this information will be forwarded to the database and made available for other interested parties to view. This program is popular on Linux, and also, being multiplatform, they could not use the DLL that I provide for generating the logging messages. However, with only a small amount of help from me, they managed in fairly short order to build their own implementation of the message generator, and start racking up the spots.

To actually make it work in fldigi you need the information from this message.

Frequently asked questions

Short answer: you want to click the Spot button in the main window. Long answer: pressing initialize with the autospot box checked should reveal a Spot button at the top right cornet of the main window. If it is unlit, the autospotter receives no data and never calls the PSK Reporter module. This may seem superfluous, but the underlying spotting "framework" is supposed to be able to accommodate other things besides PSK reporter none of which has yet materialised.Sample traces of a few digital mode transmissions as received and captured on a typical waterfall display.

The software runs on a PC that is interfaced to a radio transceiver. A waterfall display of a modern text-mode digital radio communication software displaying multiple closely spaced ongoing QSO within the baseband bandwidth of a 2.

The illustration depicts a typical configuration setup of an amateur radio station operating digital modes on the HF bands using a regular SSB transceiver. The basic concept of interfacing the PC to the radio rig using a simple cable arrangement to connect the 2-way audio input and output. An additional interface is provided to drive the PTT and the CW key input of the transceiver from the digital mode software.

For additional safety and enhanced performance, isolation transformers are recommended on each of the audio lines between the PC and the transceiver. An illustration of how a Video ID that is prepended to start of a digital transmission would appear on the waterfall display at the receiver end. The video ID may contain either or both the TX station callsign and the name of the digital mode.

MultiPSK gives a cluttered appearance and many operators often find it confusing and difficult to use. Having said that, MultiPSK which is available both as a free and a paid version is capable of encoding and decoding perhaps the largest variety of text-mode digital radio protocols in a single piece of software.

MultiPSK also features a builtin logging program with the ability to interface to amateur radio rigs. Though the logging program interface is also rather shabby, it has the ability to export the log in ADIF format for viewing in other logbook software with a better interface.

MixW Software MixW is a good text-mode digital radio software that is maintained and supported by the makers of RigExpert who offer a set of frontline antenna analyzers.

FT8Call stands on the shoulder of giants…the takeoff angle is better up there. Meaning, you will never have to pay for it, and, you can do with it what you want. From version. The windows version has been tested on windows versions 7 to 10, some users have even got it running on Windows XP. Check out the downloads section for your specific Operating System. If received in its entirety by the receiving station, these checksums will not be displayed to them.

Center is your rig center. Offset is where you are transmitting. The characters that are sent in the messages are variable encoded, ranging from 3 to 19 bits in length based on their probability of being used in a sentence. The most common characters take the least amount of space, allowing us to send more than 13 characters per transmission cycle on average.

JS8Call uses the same second transmission cycle as FT8. What is different is that due to the variable encoding of the characters, JS8Call can transmit up to 22 characters per transmission frame. If propagation is good enough for a faster mode, you should be using it instead! But, with poor conditions like we have experienced at solar minimum, JS8Call might just be the best balance. It may seem really slow and it is, relatively speaking.

However, FT8 modulation is able to decode theoretically down to dB below the noise floor. Not many modes can say this, especially those which transmit at faster speeds. What does this mean? JS8Call may work when other modes cannot. This is a friendly competition to maximize the number of continents one can pass a message back and forth to using the retransmit command. For example, this is what the outgoing and incoming messages could be:. This has been replaced, starting in version 0.

Getting Started with JS8Call – One of best things going in Digital HF!

This is a backwards incompatible release which is the primary reason for it being released right when 0. Plenty of big changes included in 0. I hope you continue to enjoy JS8. I encourage everybody to keep an open mind, but to also send me useful feedback.

Your email address will not be published. Notify me of follow-up comments by email. Notify me of new posts by email. Facebook Twitter RSS. JS8Call 0. Hi folks! First, I fixed a big decode issue, so 0.

But, because of this and some message format changes, 0. A few directed commands are a little more verbose so they are easier to remember and easier to read. The functionality is the same, they are just renamed. But, this helps illustrate the intent of them…to signal that your station is alive and on the air. Plus, the idle timer function bugs are fixed, so it works correctly and correctly reports whether or not the station is active.

It allows you to direct a message to a pre-arranged group name. So, say you want to start or join a group. Head to your settings and add the group name to the group callsigns box. Saved messages now have macro-like functionality where you can replace values in the message.Some Icons by Dryicons.

At normal speed, JS8Call transmits in blocks of 15 seconds. That's why it's really important for everyone to keep their computer clock as accurate as possible to within 2 seconds of each other. Here's an example of a block that is within the horizontal lines, so it's well synchronized with my station anyways :.

But it turns out that it was simply a lack of CPU power. The first draft of this page was copied over from VA7FI's site with permission.

Use the up and down arrows to adjust your time drift more on this below :. If everyone's computers were perfectly synchronized, all these Time Delta entries would be 0 ms. Realistically, there's always be a bit of variance, but you should try to ensure that your clock is synchronized with most other operators. The last thing to keep in mind is that this time drift might need to be adjusted periodically depending on how well your computer keeps time. Turns out that running any two of these programs is fine, but not all three.
