Something strange happened to my KX3 on S5/BR-019 summit few days ago. I started my activation on 40 m band, but did not hear any signals on CW . My TX signal was OK (verified at home looking at my RBN spots). 40 m CW band was totaly flat on my KX3 - even no increase of noise on turning on PREamplifier! Coax cable replacement did not improve situation. I was then surprised to see that SSB portion of 40 m band and CW/SSB operation on all other bands was normal! So I was happy to continue my activation.
At home the situation remained unchanged - not a single signal received on 40m CW band. I could hear CW signals in SSB mode, but all disappeared when mode was changed to CW.
Then I tried to see if something was wrong in my settings - but nothing found. So I decided to restore a configuration from a working configuration saved on my disk. So my KX3 is back to normal now.
Anyone had a similar situation / any glue what was wrong in my configuration?
