Debian Hamradio Data Modes packages

Comptty is used to compare two RTTY streams. It's comparison function uses a linear-programming technique. It computes total number of errors, the character error rate (CER) and the bit error rate (BER). Special attention is given to SHIFT and UNSHIFT to account for an error occurring in that character.

Fldigi is a modem program which supports most of the digital modes used by hamradio operators today. You can also use the program for calibrating your sound card to WWV or doing a frequency measurement test. The program also comes with a CW decoder. Fldigi is written with the help of the Fast Light Toolkit X GUI.

Flwrap is a small desktop application that encapsulates a text file, an image file, or a binary file within a set of identifier blocks. Flwrap is designed to be used to best advantage with fldigi but can be used with any digital modem program.

JTDX means "JT modes for DXing", it is being developed with main focus on the sensitivity and decoding efficiency, both in overcrowded and half empty HF band conditions. JTDX is forked from WSJT-X, a computer program dedicated to amateur radio communication using very weak signals.

The successor to multimon, with support for more modes and improved compatibility with moderns systems. It decodes the following digital transmission modes commonly found on VHF/UHF bands:

  POCSAG512 POCSAG1200 POCSAG2400
  FLEX
  EAS
  UFSK1200 CLIPFSK AFSK1200 AFSK2400 AFSK2400_2 AFSK2400_3
  HAPN4800
  FSK9600
  DTMF
  ZVEI1 ZVEI2 ZVEI3 DZVEI PZVEI
  EEA EIA CCIR
  MORSE CW
  X10

Multiple decoders can run concurrently on the same signal, which is provided via a file or a pipe. Common setups are: a radio connected via a sound card (may require modifications to the radio); samples provided via a GNU Radio sink or the UDP audio stream in gqrx (via netcat and sox).

WSJT-X implements amateur radio communication protocols or "modes" called FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon. These modes were all designed for making reliable, confirmed QSOs under extreme weak-signal conditions.

JT4, JT9, and JT65 use nearly identical message structure and source encoding (the efficient compression of standard messages used for minimal QSOs). They use timed 60-second T/R sequences synchronized with UTC. JT4 and JT65 were designed for EME ("moonbounce") on the VHF/UHF/microwave bands. JT9 is optimized for the MF, and HF bands. It is about 2 dB more sensitive than JT65 while using less than 10% of the bandwidth. Q65 offers submodes with a wide range of T/R sequence lengths and tone spacings.

FT4 and FT8 are operationally similar but use T/R cycles only 7.5 and 15 s long, respectively. MSK144 is designed for Meteor Scatter on the VHF bands. These modes offer enhanced message formats with support for nonstandard callsigns and some popular contests.

FST4 and FST4W are designed particularly for the LF and MF bands. On these bands their fundamental sensitivities are better than other WSJT-X modes with the same sequence lengths, approaching the theoretical limits for their rates of information throughput. FST4 is optimized for two-way QSOs, while FST4W is for quasi-beacon transmissions of WSPR-style messages. FST4 and FST4W do not require the strict, independent time synchronization and phase locking of modes like EbNaut.

WSPR mode implements a protocol designed for probing potential propagation paths with low-power transmissions. WSPR is fully implemented within WSJT-X, including programmable "band-hopping".

This package does not contain non-free components required for "superfox" operation. See README.Debian for more details.
