The spectrum display is divided into periods (1 minute segments) by the horizontal red lines.

In the example you can see several JT65 signals over about 6 minutes time. The 'real time'

signal will always be at the top of display down to the first red line. Notice a weak JT65 signal

at about +200 Hz offset, a stronger signal at about +750 and an unidentified signal at about

-50 Hz. Take note that the transmitted tones would begin at offset 0 as indicated by the red

TX marker should you begin transmit. And, more importantly, if you began, for isntance,

calling CQ without adjusting your TX DF (offset) you would potentially be transmitting partially

over a signal at just under your TX marker.

[For those accustomed to WSJT you will find the spectrum display both familiar and different. It looks

similar to SpecJT but it does not accept double clicks to force a decode at the clicked DF offset. JT65-

HF's spectrum display may be single left clicked to set the TX tone offset or single right clicked to set

the RX tone offset. If TxDF=RxDF is enabled then these clicks effectively do the same thing. More on

this later.]

Below the spectrum display you see the controls for it, those being Color-map, brightness,

contrast, speed, gain and smooth.

Color-map offers a choice of different color pallets for the colorized spectral data. There is no

'right' choice. I suggest trying them and see if, hopefully, one will be your favorite.
