850 Beacon Operation
Memory Based Beacon
Enabling FEATURE_BEACON and grounding left paddle at boot up will cause the keyer to go into beacon mode and repeat memory 1 continually.
SD Card Based Beacon
A beacon can also be implemented using an SD card shield. Enable FEATURE_SD_CARD_SUPPORT and on the SD card create a directory in the root directory called keyer. Place a text file called beacon.txt with your intended beacon text. This file will be sent in CW continuously at boot up. A paddle or button tap will stop the beacon sending.
