BeagleBone AI
by jks ·Think about the difficulty in implementing that in the context of the metal case assembly. Plus conduction/convection cooling is always uncertain. A fan does wonders. Also, it's more than just the cpu -

(newbie question) How can I search for DRM stations in a KiwiSDR share?
by Bjarne ·Kiwis, mixing the resulting audios into Dream. But when testing on my own two, via internet, I do hear that the signals are audibly out of sync and so will likely not decode as DRM. The only other af -
(newbie question) How can I search for DRM stations in a KiwiSDR share?
by mahaju ·I used @jks's suggestion and lauched Dream from command line and start it with the option I / Q input positive (0 Hz IF) [this is dream -c 6 in Dream 2.1.1 for Windows) and it is decoding properly wit -
(newbie question) How can I search for DRM stations in a KiwiSDR share?
by jks ·@mahaju: From your screenshot it looks like you are configuring Dream for SSB input and not I/Q input. See how your "input PSD" graph shows energy from 0 to 5 kHz whereas Martin's sh -
(newbie question) How can I search for DRM stations in a KiwiSDR share?
by G8JNJ ·Dream decoding is tricky, once you have found a station you have to fiddle with the audio level, exact frequency (look for the frequency error in Dream), SDR agc settings and RX bandwidth to get the b -

by mahaju ·I have diverted the browser output to Virtual cable, and I am using Virtual cable as input to Dream, and speaker as output of Dream -
(newbie question) How can I search for DRM stations in a KiwiSDR share?
by mahaju ·I already know how to use a Virtual Audio Cable to send the output audio from browser displaying the the shared KiwiSDR site to Dream decoder (https://hobbyradio.se/en/drm/kiwisdr.html) -
Realtime frequency/mode change via the jks-prv/kiwiclient library?
by jks ·Chris, I'm not a Python person, so I didn't even know about the sounddevice library. I think the way it works is fine. Very similar to the command line syntax for Dream (i.e. using a number to choose -
IQ File Recording Format
by jks ·I'm a little confused. Sure, people use VACs all the time to route Kiwi audio coming from a browser to decoder apps (e.g. your apps, fldigi, Dream DRM etc.) But is what you want a modified kiwiclient -

DRM demod? [yes, external app Dream now working!]
by jks ·Here's how I do it with Loopback 1.2.1 (I haven't upgraded yet) and Dream 1.11. I was never able to get Dream 2.x to work on Mac (El Cap 10.11) because of missing CODECs. But that was a long time ago -

Half Channel DRM unidentified station
by KA7U ·Picked up an unscheduled DRM transmission in English this morning. 01/25/2019, 16:46:00utc, on 13690.00kHz. The signal fades in and out, but when it is in, it decodes in the Dream receiver quite well. -

raw I/Q channels
by jks ·I should add: The biggest pain seems to be setting up the necessary software to route audio between the browser and the decoder application. It's been talked about but there is no setting currently on -
