Receiver

When receiver is tuned to a frequency where at least one transmitter is present, HUD signal meter bar shows signal power. The signal power depends on distance and direction to the transmitter.

If RDS reception is toggled on, the RDS messages from all transmitters on this frequency are enqueued and will be send one by one as a chat messages to the player with 10 seconds interval. When RDS message queue becomes empty, it refills and starts over again.
