The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation...

"CommBusTerm" is based on a "Raspberry Pi 4 Model B" or "Raspberry Pi 5", and the "kmicommbusmediator" interface. The project "kmicommbusmediator" provides connectivity for the "Raspberry Pi" to the "PPG Communication Bus" which is used by PPG synthesizers such as the "Wave 2.2", "Wave 2.3", "EVU". Link to the project "kmicommbusmediator": https://sourceforge.net/projects/kmicommbusmediator/ Application software for CommBusTerm: * "cbmedimonitor" (see "kmicommbusmediator...

"KMI Comm. Bus Mediator" ("kmicommbusmediator") The project "kmicommbusmediator" provides connectivity for the "Raspberry Pi 4 Model B" and "Raspberry Pi 5" to the "PPG Communication Bus" which is used by PPG devices such as the "Wave 2.2", "Wave 2.3", "EVU", "PRK", "Waveterm A", "Waveterm B". "kmicommbusmediator" contains hardware and software components: * "kmicommbusmediator-HW": "Comm. Bus" hardware-interface * "CBMEDIBIOS": firmware for "kmicommbusmediator-HW" * "cbmedimonitor...

Set of executable files for sending and receiving data / short multimedia files through a narrow bandwidth transmission media. The signal output to the transmitter is the sound card analog output socket while the received signal taken from the receiver is fed to a sound card analog input line. Targeted audience: * Short wave / long wave (narrow bandwidth) Amateur Radio enthusiasts * Experimenters of vintage transmission systems * People living in areas with absolutely no Internet...
