John,I updated from that fix but it still makes a busy terminal. This fixes it though.python ~/kiwiclient/kiwirecorder.py -s fenu-radio.ddns.net -p 8073 -f 3965.00 -m iq -L -5000 -H 5000 >null & It dumps the print and places the python in th…

John,I think it will record DRM. It records AM OK and I did get a partial on a weak DRM signal to record. I am very curious to see what comes of the GPS time stamp.RonKA7U

John,Since the 151 update, the older version of Kiwirecorder.py fails with the below listed run. ron@linux-4cdz:~> python ~/kiwiclient-jks-v0.1/kiwirecorder.py -s southwest.ddns.net -p 8073 -f 3955.00 -m iq -L -5000 -H 5000client_public_ip: 67.21…

Recording multiple instances using the Python coded kiwirecorder, in Linux, might require a setup of multiple users. Each user would have Python installed and each user would coordinate the recording frequencies and times with the other users. Of co…

Martin,Thank you for the available receiver. this morning I find one good recording:30 23 * * * python ~/kiwiclient-jks-v0.1/kiwirecorder.py -s southwest.ddns.net -p 8073 -f 9770.00 -m iq -L -5000 -H 5000 & 00 00 * * * for pid in $(ps -ef | aw…

After a night of 4 slices receiving WSPR the satellites rotated off the grid, so to speak, but the frequency remained true according to the magnified spectrum display on WWV @ 10.0MHz. It has been a pleasure to test with you rrobinet. It would seem …

I'm testing tonight. I have the 4 slices set for an overnight run. working 40 meters and down. Check the running report here: http://wsprnet.org/olddb?mode=html&band=all&limit=300&findcall=&findreporter=KA7U&sort=date That shoul…

Martin,Thanks for the information. I've scheduled a group to test on your receiver starting tonight. My schedule is UTC-7 so add 7 to see your time for these stations. So I'll hit your receiver fairly hard this evening. Hi Hi I'll let you know if I…

Martin,What is the UTC and duration of this broadcast? I'm running a test tonight starting at 0532 UTC and recording for 30 minutes.73,RonKA7U

Now for a cron job to start and stop the recorder. I think I might manage that... Is there a way to specify the recording length time on this recorder? So how to start and stop the kiwirecorder.py using crontab (ie. cron job)add these commands in cr…

jks,My error. The file does not play as it is recorded. The players load the file to the point it is recorded and then loop giving that impression, if I'm not really listening. So to listen to a complete recording, I should wait until the file is re…

John,Thanks for all the work you do! I just might write the author. ron@linux-4cdz:~/kiwiclient-jks-v0.1> grep -nri antarctica ../kiwifax.py:372: self.set_geo('Antarctica')./kiwirecorder.py:46: self.set_geo('Antarctica')ron@linux-4…

Another interesting aspect to this kiwirecorder.py is that the Dream receiver will play the file while the file continues to be recorded. This effectively makes a near real time connection for replay while recording, or you can come into a program l…

I tried this and the file plays in my Dream receiver just fine. I am currently recording and when I open a web browser pointed to the above URL, it opens and works just fine, but there is no indication of the recording connection. Does this recordin…

Martin,I forgot to like to a youtube video.https://www.youtube.com/watch?v=P8QRezNME8g and my blog post "how to", for whomever might benefit.http://ka7u.us/2017/11/17/kiwisdr-setup-to-use-the-dream-receiver/ RonKA7U
-
Martin,The Dream receiver is working well on my openSUSE sytem, but SoDiRa is much more difficult with DRM, it does very well with all other modes. So I use Dream for this service exclusively and think it is a fine program. I settled on "settin…
-
UR5VIB,You were the encouragement I needed! You installed on Linux Mint and that got me thinking about libfaad. It also got me thinking about my audio setup for the IQ stream input. So back to the openSUSE repo and installed libfaad for the AAC Mono…
-
sv1btl,I do not yet have a source for Sodira 0.99. I'll try it if I can find it. I suspect the Internet feed is possibly defeating the decode of DRM. I notice many restarts of the DRM receiver that I think are caused by lost packets in the feed. I p…
-
This morning I managed to lock to a DRM station here: http://southwest.ddns.net:8073/?f=3965.00iqz8 The lock did not hold long and the audio was not properly demodulated. I think the loss through the Internet feed is the biggest problem or perhaps …

Further effort with DRM decoding. I compiled DReaM on a ACER Aspire One running Ubuntu 14.04 LTS this evening. I used the script file found here:https://gist.github.com/onetransistor/4cbe3a8ab5d47da22cde The first run failed to compile looking for a…

Emmanuel, Thank you for the link to the video and the KiwiSDR. This particular thread is a Linux OS specific thread, although I think VAC will run in WA2ZKD's W7 OS running in a Virtual Box... I do have SoDiRa playing AM from the IQ input, so it do…
-
Hey Martin,I did try to decode DRM @ 3965KHz using your station this morning. Sodira would almost lock but not quite. So I was not successful with it on DRM. It does seem to work nicely on AM, but I have not tried it with the Stereo AM. The version …

I do have the loopback and the sink working properly, it was a need to select a decoder in Sodira. So now to find a DRM station to decode. Hi Hi Sodira runs great with Linux and the WINE API. I should probably write it up in my blog on ka7u.us so ot…
-
W7 running in Virtual Box took some effort to setup. Sodira is running under the WINE API on my openSUSE desktop. I can feed audio to MySink from Chrome and get recording input to Sodira from Null Output, but I have not yet setup correctly to drive …

I did get one on the October Massdrop. K7RHB might get it on the air one day.RonKA7U

In the examples given above a sound sink is created and then a monitor of that sink is used to feed audio to DREAM. The linked examples aren't using commands that Pulse Audio will accept in my version of Pulse Audio. The following commands will howe…

When you get ready to run DREAM to decode the DRM software, you will want to send the KiwiSDR audio to DREAM, but not have to listen to it in your speakers. This link should open a thread on this subject that might help you to configure your system …

Are you using Google Chrome or Chromium? I think Google Chrome is less likely to hang up with memory management problems. You can get it here:https://www.google.com/chrome/browser/beta.html The directions are a bit cryptic, so if you want it and ne…

The attached screenshot shows Chrome running KiwiSDR on a FAX line and Multipsk printing the FAX and Pavucontrol set in the "Recording" tab with the device select pull down window open to show that a "monitor of built in audio analog …

I did not mean to discourage your use of Jack. Jack offers real time audio connections and Pulseaudio introduces latency through the connection chain. Pulseaudio is built into a lot of desktop applications and they will not run without it. So if you…
