[Elecraft] K3 Power-hunting on FT8

[Dave (NK7Z)]

Hello Mike,

Thanks for sharing your data!!  Help me understand something you said...

Are you saying that at 2 bars, (for your K4), all spurious signals, are 
at least 80 dB down from carrier, while at 5 bars, all spurious signals 
are running around 50 or 60 dB down from carrier?

73, and thanks,

There is only the one strong signal present, the spurious signals being discussed here are all less than 50 or 60 dB below the intended carrier level. My goal is to reduce all the spurious responses to 80 dB below the intended carrier level.
