Fsk decoder windows

The working area of the program is divided into several windows, the sizes of which can be changed by the user by dragging the borders. In the top window the current spectrum of a signal blue line and a peak detector of spectral components green line are shown. Ruler under this window shows frequencies of sound spectrum. The long vertical red lines in this window show the working frequencies of the decoder filters. In FAX mode these lines show "black" and "white" frequencies.

To change the center frequency, click on the desired frequency probably between the peaks. The bottom window shows an oscillogram of the decoded signal. Logarithmic scale is more convenient usually, but it needs more computer resources.

The " SQL " button switches squelch on. The number to the left of the "SQL" button determines the squelch threshold. When squelch is switched on, the horizontal red line shows the squelch threshold in spectrogram window. The " AFC " button auto frequency control adjusts the long red lines working frequencies to the closest peak frequencies. The first number is local deviation in hertzs, i. Second number is global deviation in hertzs, i.

User-selected frequencies are shown at spectrogram by short red lines. These phasing lines are transmitted just before real image transmitting.

Amateur RTTY radio station and some commercial station use opposite polarity. Weather stations use 50 Baud speed. They use 85 Hz shift in the longwave band and Hz shift in shortwave bands usually. Amateur stations use 45 Baud speed and Hz shift usually. Commercial stations use 50 Baud speed and Hz shift usually. Narrow deviation is used at long wave band. When this option is selected, program can synchronize with receiving signal much faster, because it doesn't need special idle symbols to do it.

But there is chance to make incorrect synchronization in that case. Received symbols are displayed on the second from top window. A name of log file is date-stamped. For example, " TXT " is raw log file for 08 October SeaTTY finds these sequences in symbol stream and writes messages separately in the " Messages " folder. A name of message file is time-stamped. If station ID is found in a message, it is included in a filename.

For example, " KA TXT ". Filter list includes 4-symbols mask, which can consist of digits, letters, "? These messages are not human-readable and consist of groups of digits.

If message was started or stopped manually, it is saved nevertheless filter settings. The same button has " Stop " caption while message receiving and can be used to stop message receiving before "NNNN" footer.

If you install it into the Mac Applications folder or into the Windows Program Files folder or any other folder that is not writable by the applicationthen you will need to choose a different directory to write the decoded data into. You can do this the first time you run the program. Run FoxTelem by double clicking FoxTelem. On Linux, you should be able to double click FoxTelem. When FoxTelem starts then you should have the Welcome screen shown below.

The Simple install will use the installation directory to store the decoded data. This keeps everything in one place, but mixes the program with its data. Further instructions are available in the manual, which is in the installation directory and accessible from the Help menu.

FoxTelem will not start if you do not have java installed, or have a version before Java 6. You will get a message from the launcher telling you to download and install the latest version from www.

Windows gives this message for new or little know applications that have not established a reputation. MacOS has similar security precautions and will give you a message like the below:.

FoxTelem is not really damaged and it can in fact be opened. After that it will run without the Command key. If you do not know if you have 32 or 64 bit windows then Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.

Under System, you can view the system type. If you are using MacOS FoxTelem is written and compiled with the latest version of Java Version 8 in Sept but it is compliant with Java 6 so that it works on older Mac operating systems. On other platforms you can run FoxTelem with any versions of Java from Java 6, but Apple and Oracle have not made this simple on the Mac.

I wanted to use proper signal processing code. Unfortunately, now I've got it all working and I've put the transmitter back out on the oil tank where it belongs, I find it doesn't work very well. When the signal level decreases, the FM demodulation gets very poor.

Note that the amplitude of the FM demodulation appears to decrease as the amplitude of the input decreases. Which is strange, because the frequencies surely don't get closer together? The options available are:.

Heh, so much for "I don't want to have to do signal processing code so I'll just add this protocol to something that already exists" then :. I'll take a look Hi, The FSK decoder is still very young :- You are right, that the FM demodulation is currently very simple and the frequency output depends on the amplitude as well. A simple atan2 approximation may fix that. However, as the FSK decoder adapts to slowish changes of the frequency levels it should not really be a problem.

A bigger problem, is that the carrier detection OOK is non-adaptive and will declare end-of-package before the signal is gone. It is interesting with some more signals to challenge the decoder. I will have a look tomorrow and experiment a bit. Here a screenshot showing the simulated FSK demodulation, where the adaptive frequency estimators are shown.

There is some noise in the low-amplitude part, but a simulation with a true atan2 FM demodulation showed similar noise. I had to lower the OOK threshold though, so we should probably make that adaptive too. But a number of them are different. Including the one we're looking at here. Admittedly, this specific one isn't a perfect example. Normally we do expect oil tanks to remain relatively still, and we wouldn't be walking around with the sensor.

But in general it would be good to improve performance on the lower-strength signals. There is a lot of scope for layering violations here, if we know what we're looking for. By the time we get to the noisy part of the signal here, for example, we should know we're looking for signals at kHz and kHz — so the FM demodulator could be basically making a binary decision, and the results of the noise could be filtered out a little more effectively.

There are other things we could do along those lines too. Some of those feedback options are quite hard to implement, especially given the number of devices we support and the diversity of signals. But some might be feasible, so we should keep an eye out for them.

I do not think it is necessary nor desirable to use absolute frequency offsets. That would add much complexity to the code and make the decoder very sensitive to changes in tuner frequency and sampling frequency. Thanks; this seems to be an improvement.

Add -F json csv to select between json and csv. Let's start with it simple — can you bring the device close to your receiver and stick a magnet by its binding spot briefly? That'll make it stream about three reports a second, instead of one every 35 minutes.The working area of the program is divided into several windows, the sizes of which can be changed by the user by dragging the borders.

In the top window the current spectrum of a signal blue line and a peak detector of spectral components green line are shown. The vertical red lines in this window show the working frequencies of the RX filters.

In most modes you see two vertical line; in PSK modes - only one. To change the center frequency, click on the desired frequency probably between the peaks. In MultiFSK mode mouse click defines lowest radio frequency, not center one. The short thick black lines show TX frequencies. To change the TX frequency, click on the desired frequency by right mouse button or the left mouse button with "Ctrl" key pressed.

Ruler under top window shows frequencies of sound spectrum. RX and TX frequencies and shifts are also shown in the status line. You can use keyboard and screen buttons located below spectrogram ruler for fine tuning. These screen buttons can be used for TX frequency changing also. TX sound frequency is changed if right mouse button is used or "Ctrl" key is pressed.

The logarithmic scale is usually more convenient, but it uses more computer resources. The " SQL " button turns squelch on.

The number to the left of the "SQL" button determines the squelch threshold. When squelch is switched on, the horizontal red line shows the squelch threshold. The " Zoom " menu and " Alt-1 " To move a visible part of spectrogram or waterfall to left or right drag it by mouse with Alt key down. A phase indicator can be used for fine tuning in PSK modes.

In ideal conditions you see immovable or slow rotating line there. Faster rotation means more frequency error. The third from top window shows an oscillogram of the decoded signal. The received text is displayed on the second from top window.

When the RX buffer has grown to about 20kB, part of the data is moved into an invisible buffer.
