V1.6.0 is the first _WSJT-X_ version to include features specifically

designed for use on VHF and higher bands. These features include *JT4*,

a mode particularly useful for EME on the microwave bands; *Echo* mode,
|

for detecting and measuring your own lunar echoes; and automatic
|
||||
*Doppler tracking* for the EME path. (Note that sub-modes JT65B and

||||
JT65C are present in v1.6.0, but are not yet fully implemented for EME
|

purposes.)
