|RFI issue spread across the band|
- Switched to my active antenna and I still had the issue.
- I change to battery power only and I still had the issue.
- I turned off the main AC circuit breaker to the house and I still had the issue while using battery power obviously. Oh and an added note.....my dear wife was not happy about that.
|Sometimes the RFI stops but then soon starts|
-Switched to my dummy load and the issue was gone but so were all signals.
So from the above, it seems it is being picked up by the antenna and not something within my home. At this point, I have not tried to pinpoint times as to when or if the RFI is present. I will be within the next few weeks paying very close attention to times when I am on and if the RFI is present or not. Until then I wanted to see if I was able to solve the issue with the Icom 7610's filtering. The choices I have are the noise reduction option or the noise blanker option. As a side note, my previous rig was the Elecraft K3 and it had amazing filtering for RFI issues. It was time to put the Icom 7610 to the test and see how it performed. I tried both the NR and NB and found it was the NB (noise blanker) that did the trick. I was able to totally remove the RFI and still hear the CW signal that was getting buried in the noise. Within the noise blanker settings, you can adjust the level, depth and width. I did find certain settings worked better than others at removing the offending RFI. I did change over to my Elecraft KX3 just to see how it dealt with the RFI and I was shocked how it really was not able to remove the RFI and the Icom 7610 won hands down!
