Listening to someone on 10m CW send "<callsign> ek 19mm" followed by a long tone over and over and over. It's a real callsign from MX operating with /b suffix. Any idea what this would mean?
It's on 28.275 if anyone is interested.
@K0GDB contest?
@vk6flab Totally possible, just couldn't find anything online.
@K0GDB The /b is giving it away. It is a beacon. There are many between 28200 and 28300. They are used to check propagation.
@g0syp Ahhh, that makes sense. Thanks!
