I have been having a blast lately with digital modes like PSK-31 and JT-65/JT-9. My little KX3 is doing a great job even without having run the temperature compensation. Of course I am keeping my power to 2 or 3 watts – which helps a lot.
I have noticed a strange thing for a while, but I am just now getting around to asking about it.
When I look at the waterfall there is an area that is basically blanked out – for lack of a better term.
Here is a screen shot of the waterfall in WSJTX (JT-65). You will notice the black area on the left.
|Waterfall of WSJTX – What is “black” on left edge?|
As you can see there is an area on the left that is in the frequency range, but it is “blacked out”. I wonder how many signals are in this area?
Those if you with a KX3 or those of you that might know what this is – please let me know! If you know how to fix this, please let me know that as well!
I am looking forward to hearing the responses – I appreciate the help!
