(you have to add your own cables to the kit) I have heard the Texas FSQ Digital net also talk about their use of these low cost kits which has prompted me to post them here in the Digital section of Corps.Ĭurrently I have tested them on a Raspberry Pi3 along with this $7.95 TRRS sound card. ![]() I got both an entire complete setup and the 2 board kit that sells for $7.95. Hi folks, I have tested these “Easy Digi” since May 2018. Flwrap is a file encapsulation and compression tool allowing for reception of a file exactly like the original. Flmsg is a forms manager with standardized forms like MARS, plaintext messages, Radiograms, Red Cross, and Weather report forms. This comes in to your computer through your sound card, so you can decode these signals into text from a Shortwave Radio Receiver or even a recorded audio file.Ĭlick HERE to learn more about digital communications.ĭigital Communications Downloads: Ham Radio Deluxe FLAMP FLDIGI RMS Express Fldigi stands for Fast Light Digital modem application created by W1HKJ (David Freese, Jr.) and associates. Note: No Ham Radio License required to receive digital communications. Digital communications Send or receive text messages over radio using your computer’s sound card or using a Signalink. ![]() However, it does not require an internet connection for transmitting and receiving-it uses radio waves. It just sounds like a ‘humming or buzzing’ noise while transmitting to anyone monitoring the frequency without the digital equipment.ĭigital communications does require a computer since it uses software such as fldigi. Another benefit is, digital communication can only be “decoded” by others set up for digital communications. by LRS President Andy Sinclair MM0FMF.Digital communications requires less power, transmits farther and is reliable even in poor conditions. It is used with the Raspberry Pi -Zero.Īfter his talk, John was thanked and presented with. The Funcube dongle for schools to track Funcube satellites costs 'only' £150 but the DVB-T dongle performs almost as well and costs only £10. John's second demonstration was fldigi which can be used for PSK-31 etc. The antenna could be just a piece of wire but John uses an 8-element vertical collinear made from coax.ĪDS-B demo showing the locations of all the aeroplanes detected and identified.Ĭlick for website 'ADS-B using dump1090 for the Raspberry Pi' (David Taylor GM8ARV) The receiver could be a USB-DVB-T stick (£10) or (better) an RTL2832U + R820T, on 1.09GHz.
