Starting Point Receiver Settings For FT8 On 6400

N3PS

Any words of wisdom for the starting point receiver settings for operating FT8?

I currently have NB, NR and ANF disabled. AGC is set at MED, and the slider at 60.

I realize that everything is band and band condition dependent, but is the above a good starting point ?

Yes, that's a good starting point. Others have different habits, but I run my AGC lower, at about 20.. Just enough to get green on the WSJT level indicator on Antenna noise. The thing to remember is that the WSJT decoders are very forgiving when used with the FLex. They don't need any help from radio processing.

The AGC-T slider is one of the more powerful tools. 60 sounds a bit high. You actually set it so that you radio sound quieter and you can do this safely without loosing the ability to copy weak signals.

The background noise on your radio should NOT sound like a typical super-het radio. In the SmartSDR User Guide, it is explained how it works and why it is so important.

While this video says 6000 series it works on all series.
