There is a glitch when Tony goes to switch to SSB. That's fading, probably from two reflections arriving out of phase. Also note the diagonal black streaks across the waterfall display. The SSB bandwidth is about 3 times that of the digital audio. A USB microphone headset is required for voice input / outputįreeDV, the new HF digital audio program for Radio Amateurs It can be used with any SSB HF rig with a computer and sound card setup similar to what is used to run PSK31. It runs efficiently under Windows and does not require any transceiver modifications. WinDRM provides an efficient and robust method to exchange information over HF including Digital Voice. It uses an open source encoder/decoder called DREAM. WinDRM was developed by Cesco, HB9TLK from the broadcast standard known as Digital Radio Mondiale (DRM). WinDRM HF QSO with K0PFX and K2MO LPC 10 CODEC It fills a gap in open source, free-as-in-speech voice codecs beneath 5000 bit/s and is released under the GNU Lesser General Public License (LGPL) Codec 2 operating at 2000 bit/s can send 32 phone calls using the bandwidth required for one 64 kbit/s uncompressed phone call. Applications include low bandwidth HF/VHF digital radio and VOIP trunking. TCodec 2 - Open Source Speech Coding at 2400 bit/s and BelowĬodec2 is an open source low bit rate speech codec designed for communications quality speech at around 2400 bit/s. There are various modes such as XSL, TADIL, HFDL, Pactor, CW, HF Fax, Packet, JT, ALE, DRM, RTTY and various OFDM schemes Sounds of HF Radio - Digital Modes and other Unusual SoundsĪ collection of various digital modes used by utilities, mariners and amateur radio users.

Traditionally this is done with a hardware interface. Use of PowerSDR with digi-modes requires a means to interface the AFSK between the program and the hardware.
