//
// Communications Mode ? AMS,FM DN,DW   TX vs RX?
// Mode not currently correctly stored in memories ? - ALL show as FM in memories
// SKIP test/where stored
// Check storage of steps
// Pager settings ?
// Triple check/ understand _memsize and _block_lengths
// Bank name label name size display 6 store 16? padded with 0xFF same for MYCALL and message
