Questions have come up on the recent release of the Shera code. All
software commands with the exception of Auto N get lost in case of power
failure.
Auto N is stored in EEPROM. After power fail Dip switches take over. Alpha
filter can be activated with software commands or switch #5. #5 can be DAC
Hold or Alpha present compiled code is Alpha. An open switch on #5 is
Alpha on. In manual or auto N Alpha is first engaged in filter 4 position. If
auto N is enabled and there is a power fail and #5 is open code will run up
to the value selected by the Dip switches and once it reaches 4 enables
Alpha filter. Also some status commands have been added listed below

; +10 glitch detected

; +50 alpha filter enabled
