Block a callsign

General
1

Hello.

Is there a way to block particular callsign? Recently, there is a lot of bad decodes from 40m CW station reported as 5n6mew and 5n6aew because of poor operator keying. Can I block them forever somehow? Not for 6 hours.

Thanks, Mike

You could add a “Not callsign” condition to your trigger(s).

Specifically, click on Add a condition | Call sign exclusions | not Spotter callsign.

Thank you for reply.

Unfortunately it does not work. Soon gives Ambiguous trigger and it’s disabled.

Any other option?

Thank you. Mike

You need to add this condition to your existing trigger(s), possibly all of them if they also match 40m CW. If you create a separate trigger with only a “not Callsign” condition, what you’re effectively telling HamAlert is that you want all spots (i.e. around 40 million per day), except those for the listed callsigns.

Also note the difference in the two conditions:

  • not Spotter callsign: matches the callsign of the station that sent the spot
  • not Callsign: matches the callsign of the station that was spotted

From your problem description above, it seems that you probably want a “not Callsign” condition, as the problem is not the spotter (RBN stations), but the poor keying of the operator sending his own callsign.
