Each packet contains information on the location of the transmitter, so you can see where and how far away the packet you've received comes from. WSPR is also not as active as FT8, although WSPR is more of a beacon mode rather one used for making contacts.Īpart from being used by hams to make contacts, these weak signal modes are also valuable indicators of the current HF propagation conditions. Released in 2017, FT8 has shown itself to now be the most popular mode by far with JT9 and JT65 taking a backseat. The special design of these modes allows even weak signals to be decodable by the receiving software. QRP digital modes such as FT8, JT9, JT65 and WSPR are modes designed to be transmit and received across the world on low transmit powers (although not everyone uses only low power). QRP is amateur radio slang for 'low transmit power'. JTutorial: Setting up a Low Cost QRP (FT8, JT9, WSPR etc) Monitoring Station with an RTL-SDR V3 and Raspberry Pi 3

If your audio is choppy you may consider turning off Wifi and disabling it all together, or use a USB wifi adapter, or do the opposite and use a USB Bluetooth Dongle and disable the onboard bluetooth or use it for other things.

I learned a lot from these links but never really got all the bluetooth speakers playing at once, so these are just useful hints from the rabbit hole. usr/bin/mplayer -ao pulse ~/sounds/fckYes.mp3 I was able to pair, trust, and a bluetooth a2dp sink was created and my speakers started working with: # Automatically load driver modules for Bluetooth hardware /etc/pulseaudio/system.pa

By adding the following lines and running pulseaudio as a system user (root) despite the warnings in my console telling me something was wrong with me. See comment, on the previous article, there was something missing that made all of this work for me using Pulseaudio and mentioned adding the additional line for module-bluetooth-policy so that I could actually trust and pair my devices. Running PulseAudio on Bluez5 using Bluetooth see comment.Running PulseAudio on Bluez5 without BlueAlsa.The next link seems the best solution right now if you want to combine multiple audio outputs into a single aggregate device through something like PulseAudio`` (like playing across multiple bluetooth speakers) It does not use BlueAlsa which at this point I am in favor of due to the massive amount of work BlueAlsa package still needs to fix a few things and possibly incorporate an alsa plugin for the pcm that allows it to be used as 'multi' or 'dmix'. I spent days researching, trying different things, and so far, these are the most useful links I have found and tested.

Somehow, bluetooth became a serious mess with Alsa, especially on the Raspberry Pi Rasbian Stretch OS. The Bluetooth on Raspbian Stretch Bluez-Alsa / BlueAlsa with or without PulseAudio Conundrum To do that, I used a separate memory card and setup Raspberry Pi Raspbian Stretch default (non N00bs) install. In my experience, I started off with Jesse and later decided to backup my /home/pi and /etc configuration files, and start fresh with Stretch. For example, Pulse Audio is no longer recommended or required, as bluez or BlueAlsa have replaced the older stuff. In March of 2018, RASPBIAN STRETCH was released for Raspberry Pi and major updates to the bluetooth and audio handling have been implemented.
