CW Skimmer is a multi-channel Morse code decoder and analyzer program for Microsoft Windows.It was created by Alex Shovkoplyas, VE3NEA, and is marketed by Afreet Software, Inc.
The latest version of WSJT (not to be confused with WSJT-X) is written in Python and C, with several utilities written in Fortran. [ 3 ] WSJT versions up through 7.06 r1933 (referred to as colloquially as WSJT7) and earlier were aggregations of previous versions, and as such WSJT7 contained 16 different modes (FSK441, JT6M, JT65 variants A - C ...
Fldigi (short for Fast light digital) [4] is a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem.The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB or FM transceiver to the computer's headphone and microphone connections, respectively.
HE-AAC is also used by AOL Radio and Pandora Radio clients to deliver high-fidelity music at low bitrates. iTunes 9.2 and iOS 4 include full decoding of HE-AAC v2 parametric stereo streams. iTunes 9 thru 9.1, iPhone OS 3.1 and Fall 2009 iPods have support for HE-AAC playback for version 1 with no parametric stereo.
After version 10.0.0, 64-bit codecs are integrated into the regular editions. Prior to this version there was a 64-bit edition designed specifically for 64-bit OSes. After version 11.3.0, the 32-bit and 64-bit versions of LAV Filters share their settings, and an option to install only 64-bit codecs was added (visible only in Expert install mode).
It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT. The software code is now open source and is developed by a small team.
bit 4: If set, bytes 0–5 (signal format) are unreliable. bit 5: If set, bytes 6–13 (channel labels) are unreliable. bit 6: If set, bytes 14–17 (sample address) are unreliable. bit 7: If set, bytes 18–21 (timestamp) are unreliable. Byte 23: CRC. This byte is used to detect corruption of the channel status word, as might be caused by ...
FT8 involves 77-bit message blocks transmitted in regular 15-second periods, consisting of 12.64 seconds of transmission time and 2.36 seconds of decode time, giving a digital data rate of 6.09 bits/sec. Source encoding gives an effective message throughput equivalent to about 5 words per minute.
