Working frequencies can be for all regions or for individual IARU regions. This allows each mode band tuple to have one or more working frequencies which can include local ones only offered when the user configures their IARU region. Change working frequency default suggestions to better fit in FT8. General rule is FT8 is at JT65 -2kHz except where that is not possible e.g. where that would fall into a segment not allocated for narrow band data modes. For tight bands like top band sqeeze existing JT65 and JT allocations to allow space for FT8. NOTE: this change changes the WSPR frequency on 80m to allow access to JA stations that currently have no allocation where it was placed. ALSO NOTE: the JT65 and JT9 frequencies for 80m move down 6 kHz, again to accommodate region 3 users. Other appliactions not within our control should be asked to move in step when 1.8.0 is released. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@7810 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

WSJT-X is a computer program designed to facilitate basic amateur radio communication using very weak signals. The first four letters in the program name stand for “Weak Signal communication by K1JT,” while the suffix “-X” indicates that WSJT-X started as an extended (and experimental) branch of the program WSJT. WSJT-X Version 1.6 offers five protocols or “modes”: JT4, JT9, JT65 WSPR, and Echo. The first three are designed for making reliable QSOs under extreme weak-signal conditions. They use nearly identical message structure and source encoding. JT65 was designed for EME (“moonbounce”) on the VHF/UHF bands and has also proven very effective for worldwide QRP communication on the HF bands. JT9 is optimized for the LF, MF, and lower HF bands. It is 2 dB more sensitive than JT65 while using less than 10% of the bandwidth. JT4 offers a wide variety of tone spacings and has proved very effective for EME on microwave bands up to 24 GHz. All three of these modes use one-minute timed sequences of alternating transmission and reception, so a minimal QSO takes four to six minutes — two or three transmissions by each station, one sending in odd UTC minutes and the other even. On the HF bands, world-wide QSOs are possible using power levels of a few watts and compromise antennas. On VHF bands and higher, QSOs are possible (by EME and other propagation types) at signal levels 10 to 15 dB below those required for CW. WSPR (pronounced “whisper”) stands for Weak Signal Propagation Reporter. The WSPR protocol was designed for probing potential propagation paths using low-power transmissions. WSPR messages normally carry the transmitting station’s callsign, grid locator, and transmitter power in dBm, and they can be decoded at signal-to-noise ratios as low as -28 dB in a 2500 Hz bandwidth. WSPR users with internet access can automatically upload their reception reports to a central database called {wsprnet} that provides a mapping facility, archival storage, and many other features. Echo mode allows you to detect and measure your own lunar echoes, even if they are far below the audible threshold. WSJT-X provides spectral displays for passbands up to 5 kHz, flexible rig control for nearly all modern radios used by amateurs, and a wide variety of special aids such as automatic Doppler tracking for EME QSOs and Echo testing. The program runs equally well on Windows, Macintosh, and Linux systems, and installation packages are available for all three platforms.
