HI All, since the upgrade of the 8k6 Flex to v401 and the last SDC v1903

I am experiencing strange behaviour , look at the attached pic.

On 30mt at 10100 the omnipresent RTTY carrier on SDC give false calls.

On the old versions I have never seen a decoded call as it is RTTY not CW

I have tried to change the settings in the Skimmer menu but nothing changes.

Nothing bad just annoying ...

Do you have any suggestion ?

Phil, the version of the program doesn't matter.

1. You allowed the skimmer to search for callsigns where amateur stations should not be.

2. You have disabled the callsign verification.

3. You have allowed the skimmer to send spots for stations that are not operating in CQ mode.

Result: Any combination of letters and numbers that complies with the rules for forming amateur callsigns is considered a normal callsign by the skimmer and a spot is sent.
