![]() Using this setup, multiple receivers either local or over the internet can then be configured to dump all the identified frequencies, powers, and time stamps into DragonOS. #Universal walkie talkie programming software software#The video includes the setup of the software and its use in detecting these signals, but also includes setup of influxdb and Grafana which provide logging capabilities as well. This build uses two RTL-SDR devices paired with the DragonOS software suite to automatically detect active frequencies within a specified frequency range and that aslo exceed a threshold measured above the average noise floor. The latest is a video about using this software to detect radio signals in certain specified spectrums. Since then, the creator of the OS, has been busy adding features to the distribution as well as creating plenty of videos which show off its capabilities and also function as how-tos for people who might want to learn about software-defined radio. ![]() If you prefer something more analog, grab seven transistors and build this SSB transceiver.Ĭontinue reading “Ham Radio SSB Transceiver Fits In Pocket” → Posted in Radio Hacks, Reviews Tagged ham radio, QRP, sdr, software-defined radioĭragonOS, a Debian-based Linux distribution specifically packaged for software-defined radio functionality, roared onto the wavelengths during the beginnings of the various pandemic lockdowns last year. ![]() You might borrow an antenna idea from him, at least. This is a bit pricey for $50 Ham series, but not by much. Towards the end of the video, you can see the radio make some contacts, too. Looking inside, the radio looks surprisingly well made. According to commenters, the radio doesn’t have an internal charging circuit, so you have to be careful what you plug into the charging port. There are also ports for a key, external microphone and speakers, and audio connections that look like they’d work for digital modes. There are ports for power to run the radio if you want to not use the battery and a separate port for battery charging. There are a few buttons, a rotary encoder, and an LCD along with a speaker and microphone built-in. There isn’t much on the front of the radio. There are several variations of the radio available and they cost generally less than $200 - sometimes quite a bit less. SSB is an odd choice for low power operation, although we wonder if you couldn’t feed digital data in using a mode like PSK31 that has good performance at low power. You can see his video about the gear below. ![]() The radio is a clone of a German project and provides a low-power radio with a rechargeable battery. does a nice job of unboxing the rig and checking it out. Talking about this Chinese ham radio transceiver requires a veritable flurry of acronyms: HF, SSB, QRP, and SDR to start with. Of course, canned applications are great, but if you get one of these, you are going to want to try GNU Radio.Ĭontinue reading “TRX-Duo Is A Red Pitaya Clone For Software Defined Radio” → Posted in Radio Hacks Tagged Red Pitaya, sdr, software-defined radio You can do a lot more with a transmitting SDR - having both transmit and receive opens up many new projects. However, for something comparable, you will pay more for the Red Pitaya and - depending on capabilities - perhaps a lot more, although you do get more capability for the increased price. You can get a less capable Red Pitaya model for about $100 less than the going price. It was, however, able to hear the world easily. Using the box as a WSPR beacon, it was heard fairly well given the low output power. The device shows a browser menu with various options and the result is quite impressive. One has a number of applications that run on the device and will also run on a Red Pitaya. The board boots off an SD card and there are several to choose from. Connectivity: Ethernet and USB connectivity (WiFi with a dongle).CPU: Zynq SoC with a dual-core ARM Cortex A9.The device is pretty powerful compared to a cheap software defined radio: ![]() Sure, you can pick up an RTL-SDR dongle for a fraction of the price, but then you miss out on transmitting. While this unit isn’t inexpensive, it also isn’t as expensive as some of its competitors. obliges with a review of the Red device in the video below. If you’ve noticed the TRX-DUO software-defined radio transceiver, you might have wondered how it stacks up to other choices like Red Pitaya or HackRF. ![]()
