Activate this -feature by setting a spinner control *Max Drift* on the _WSJT-X_ main -window to a number greater than 0. We suggest a setting of 10 for -submode Q65-60A, the recommended submode for EME on 50 and 144 MHz, -which will accommodate drift rates up to 20 Hz/minute. Similarly, we -suggest *Max Drift* = 40 for submode Q65-15C, used for for 10 GHz QSOs -(up to 900 km) via aircraft scatter and drift rates up to about 20 -Hz/s. When *Max Drift* = 50 the decoder will use an enhanced algorithm -to compensate for larger aircraft scatter drift rates, successful -decodes with this algorithm are tagged with a `q5` indicator. +_WSJT-X 2.6_ implements features in support of the ARRL International +Digital Contest. This contest's scoring is distance based, so the +*Call 1st* checkbox is replaced by a drop-down control offering *CQ +Max Dist* as an alternative. A new window labeled *Active Stations* +displays a list of received but unworked callsigns sorted in +decreasing order of potential contest points. See Section 7.4 for +more details on these features. + +Decoding performance for FT8 and Q65 has been improved for situations +where _a priori_ (AP) information is available. + +*Echo* mode now offers a button labeled *Clear Avg* and produces +reliable measurements of SNR and Doppler spread. The related +*Measure* function can be used to measure these quantities for a +received unmodulated carrier -- for example, a key-down test signal +emitted by another station and reflected from the Moon. + +New buttons on the main window allow quick changes between the modes +FT4, FT8, MSK144, Q65, and JT65. Another button allows toggling the +FT8 Hound mode ON or OFF. + +Optional highlighting is provided for DX Call and DX Grid, and for +messages containing RR73 or 73. + +New options are provided for writing to file ALL.TXT. You can request +starting a suitably labeled new file every month or every year, and you +can disable writing altogether. -On the Windows platform only, _WSJT-X 2.5_ installations now include -an early version of _MAP65 3.0_. This program works together with -suitable hardware that converts RF to baseband. The hardware/software -combination implements a wideband, highly optimized receiver for the -Q65 and JT65 protocols, with matching transmitting features that -require a standard SSB transceiver. _MAP65_ is effective in both -single-polarization and dual-polarization systems. If two -polarization channels are available, _MAP65_ determines and matches -the linear polarization angle of each decodable signal. This -capability provides a major advantage for efficient EME communication -on bands up to 432 MHz. A single-channel _MAP65_ system works -extremely well for EME on 1296 MHz and higher bands, displaying all -signals in a 90 kHz sub-band and decoding all the Q65 and JT65 -signals.
