[Elecraft] [PX3] - symmetrical reflections about the center point
Not sure if it was the loading of the new KX3 firmware, or if I changed some settings, but now on my PX3 panadapter, I see everything symmetrically mirrored around the center. So for example, If there is a signal at Center frequency -50kHz, it appears at +50kHz too. As I move the VFO, the signals eventually converge and pass through the middle on their way to the ends of the display.Anyone have any idea how to fix this, or what I did to get in this mess?thank you -Kevin (KK4YEL) __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Kevin, That is what happens if only one of the I/Q channels is connected. Make certain your I/Q cable is fully inserted - check both ends. 73, Don W3FPR On 1/10/2016 7:42 AM, kevino z wrote: Not sure if it was the loading of the new KX3 firmware, or if I changed some settings, but now on my PX3 panadapter, I see everything symmetrically mirrored around the center.

Hi Kevin, Try removing each end of the IQ cable between the KX3 and PX3 and firmly re-inserting it. What you are seeing usually is the result of one end not being fully inserted in the jack, leaving one of the IQ lines open.

Thank you - that did it - The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence. > On Jan 14, 2016, at 14:55, Eric Swartz - WA6HHQ, Elecraft > wrote: > > Hi Kevin, > > Try removing each end of the IQ cable between the KX3 and PX3 and firmly > re-inserting it.
