Change History
==============
13/06/2019 - V1.8.29
--------------------
Fixed bug where only the first sentence in a multi-sentence packet was uploaded to Habitat
Fixed bug where the message uplink sent 255 bytes even if message was shorter
Fixed bug where after leaving help screen screen shows original frequency not AFC'd frequency
Fixed bug where AFC correction was lost after uplink
AFC correction is now upplied to uplink
09/05/2019 - V1.8.28
--------------------
