Hi Bill , sorry on the WDT I stepped through going up to the maximum, OK on the protocol change for 30 sec period, I've tried editing the standard messages , even putting the QRA locator in the Callsign box so it appears first, but the callsign gets truncated from "G8JVM/B" to "G8JVM/" It would be a nice feature to be able to show that your are in beacon mode by adding a /B to the callsign, or what maybe easy to implement , to allow "/B" to be allowed in the report field, so it would send "IO82SP G8JVM /B", would it be possible to add "/B" as a legitimate entry in the report field to indicate you are in beacon mode. Thanks
