General 1 month, 2 weeks agoAfter re-subscribing, it seems like updates are not being sent for topics that existed before the software upgrade. At least that’s what I’m noticing. You can re-subscribe to individual historical topics to get around this.

Mike, KJ6VCP replied to the topic 2019 Simplex Test in the forum
General 2 months, 1 week agoI have updated the final report to the library.
This has a summary of who heard who, and a map for each station plotting the results.

I have raw data if anyone is interested in more analysis. Also, the maps are just snapshots – the live version is more fun but I don’t have an easy way to host them.

General 3 months, 1 week agoIf you select listen-only, I’ll assume you are not transmitting. Mostly, a listen only registration will collect the location info, which is not public but will let us create a map of the results.
