Thank you! I understood. This is as I suspected.
-
I checked, but IQ packets seem to be in mono (real+imaginary part). I did some raw testing and I suspect that DRM is not presented in IQ format as a real+imaginary value, but as a pcm encoded stereo signal (different from IQ). So I suspect: IQ forma…
-
I finally managed to decode DRM, but the audio is distorted. Is decoded DRM data sent in the same format as IQ (which I can interpret correctly)? Is it sent in stereo or mono? What is the sample rate? what do you mean by: mono: hdr 10 data 1024 mono…
-
Is there an flag in the header indicating it is an IQ packet?
-
I am sorry I do not write for iOS. If you bought a coffee and entered the key you received, you will not get the fading DEMO text over the waterfall and the waterfall smoothly fading out after 20 minutes. Maybe I should add an indication that the se…

Just now saw all these comments (i was talking in another thread with jks, will use this one now ;-)) I am currently fixing a lot of problems, like the 2 connections will be 1 for all (wf, snd and ext). Fixing other problems like enter in the search…

Another question when using DRM: Before the DRM decoder locks, the SND socket keeps sending audio packets with lots of 00 and 01... Is there a flag in the header that I could test on to check if the audio packet has valid information? If so I can te…
-
You can ignore this below, because I already found the reason (the id's in the ws//<url> should be the same for all sockets) Thank you. I try to implement DRM decoding following your instructions. When the user selects DRM mode, I send this t…
-
Thank you, but I still do not understand how to interpret the audio data when in DRM mode. Is the audio data also sent over the SND socket when in DRM mode? Problem is that when I tune into a DRM station, I only get ticking noises from the SND socke…
-
Thank you. I see that at start, the client opens 2 sockets to the server: a SND socket for the audio and an F socket for the waterfall. When the user switches to DRM, an EXT socket is opened and packets are read after sending a few commands like &qu…

There are different LCD color themes: https://forum.kiwisdr.com/uploads/312/KIQ7EIMHU5HA.jpg https://forum.kiwisdr.com/uploads/712/CE9BUU0YM6YC.jpg https://forum.kiwisdr.com/uploads/756/NFELEKGCYDBC.jpg https://forum.kiwisdr.com/uploads/389/TCK74W1L…

Found out myself: even if squelch is on, audio packets are sent back, but client has to blank them out depending on flag 0x0040 (squelch flag).
-
@jks I have a question about SQUELCH: Is the SQUELCH filtering done at the KiwiServer side, or do I have to provide my own Squelch algorithm in the client? I send the SET squelch=<1-40> param=0.00 (max) command to the server, but it does not a…
-
From some servers I receive these messages on the sockets: On the waterfall socket (and the waterfall does not start): MSG badp=5 On the audio socket (and the audio stops): MSG monitor What does it mean? Also I notice that some servers se…
-
My SDR Radio is almost functional. But I still cannot create a SQUELCH function. I need help for this protocol. I use the following commands: SET squelch=0 param=0.00 (off) SET squelch=<1-40> param=0.00 (max) However, it does not work. What am…

deleted because redundant
-
Version 18 is now ready. Many features now work, like signal meter, compression, noise reduction, noise blanker, spend 1 day on reworking the audio decoder, now cracking and chopping solved.but lots of work to do... https://forum.kiwisdr.com/uploads…

I need help: I try to implement the SQUELCH function. After sniffing in the browser, I found the format: SET squelch=0 param=0.00 (off) SET squelch=40 param=0.00 (max) However, it does not work. What am I doing wrong? Do I need to specify more para…

Noise reduction command works like: NR off: SET nr algo=0 NR on SET nr algo=3 SET nr type=0 param=0 pval=1 SET nr type=0 param=1 pval=0.95 SET nr type=0 param=2 pval=100 SET nr type=0 param=3 pval=0 SET nr type=0 en=1 SET nr type=1 param=0 pval=1 S…

Thank you for your information! This is the latest release 12 and the new waterfall. Color settings can now be changed. https://forum.kiwisdr.com/uploads/965/SHMG5QYDNUWX.png Still have difficulties to derive a significant s-meter. Help is welcome. …
-
How often should I send a keepalive signal on the socket? I now set it to 5 seconds.
-
Thank you that is helpful information! It is a pity there is no real protocol documentation or wiki. Another thing I search for is how can I implement NR (Noise reduction). Is there a command ("SET ...) to send that info? And what values can it…
-
I have to implement a signal meter. How and where can I find the signal information? Is there a need for a separate socket to open or can I find it in the audio socket data somewhere?
-
Implemented the bands and the correct zoom factor for the waterfall. Implemented the different modulations and the according lo and hi bw Implemented the scrolling over the waterfall and displaying the bandwidth Implemented scrolling outside the wat…

Prototype with waterfall is now working: todo: bugs, bugs, bugs implement band buttons, nr, squelch, memory handling, serverlist selection box and so much more https://forum.kiwisdr.com/uploads/289/GHWEYIY8BCJL.png
-
It should run on IOS and Android and HTML (pc/linux). I am busy translating my prototype to javascript and HTML. So it should work on all platforms. I wrap it later using Android studio in an apk.
-
I extended my interface prototype (waterfall not yet implemented here) https://forum.kiwisdr.com/uploads/742/VBPAK65BZB3T.png
-
It is a very early prototype to test the principles and guide myself towards the interface I want to build. I would like to create the nostalgia of the old Kenwood receivers, simplified and combined with a waterfall interface and translated into a p…
-
Have to integrate prototype 1 and 2. Still a lot of work to do and debugging.
-
Interface working towards something like this (raw prototype), should run on mobile. https://forum.kiwisdr.com/uploads/192/7DXXMOWYIK47.jpg
