Version 4.0.9

doc update

clock_gettime * Change np-compat.m4 to provide for conditional use of library calls to clock_gettime - allow for compiling on OS X < 10.12 using Xcode 8.xxx - use ./configure --without-clock_gettime

spectrum display * Changed from fft mode to spectrum display paradigm - spectrum display available independent of digital mode in use. - spectrum display dialog opens from "View" menu - removed all code relating to the original fftscan modem - added new fltk widget, spectrum based on fldigi's digiscope widget

Test Signal Dialog * Correct IMD range controls

dxcluster fonts * fix dxreport font rendition * add resizable groups to correctly resize tabs

Spot buffer * add clear RE buffer after a successfull match

Winkeyer clones * added longer time out for character echo. - requirement for ZLP clone of Winkeyer http://www.g4zlp.co.uk/unified/DigiMaster_CW.htm

RX Text capture * Fix loss of capture when Rx text scrolls or user's mouse clicks off of the target

PSK s/n imd * Changed s/n display code to avoid displaying misleading values * Changed Noise/Offset/IMD test signal generator IMD can be specified in dB and signal will correctly emulate an over driven transmit signal. IMD generator modified to correctly computer 3rd, 5th, 7th and 9th harmonics of PSK fundamental (15.625 Hertz). * Removed "--noise" command line parameter * Added Test Signal Dialog with S/N IMD tx freq offset controls * disabled display of Rx IMD, s/n values if |imd| > |s/n|

PSK viewer * Added the following modes to the multi-channel viewer - PSK31, PSK63, PSK63F, PSK125, PSK250, PSK500 - PSK125R, PSK250R, PSK500R - QPSK31, QPSK63, QPSK125, QPSK250, QPSK500
