//

// 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

// CHIRP mode DIG not supported - is there a CHIRP Fusion mode? Auto?

// Check character set

// Supported Modes ?

// Supported Bands ?

// rf.has_dtcs_polarity = False - think radio supports DTCS polarity

// rf.memory_bounds = (1, 900) - should this be 0? as zero displays as blank

// RPT offsets (stored per band) not included.

// 59 Display radio firmware version info and Radio ID?

// Front Panel settings power etc?

// Banks and VFO?

// Features Required

// Default AMS and Memory name (in mem extras) to enabled.

// Bugs

// MYCALL and Opening Message errors if not 10 characters

// Values greater than one sometimes stored as whole bytes, these need to be refactored into bit fields

// to prevent accidental overwriting of adjacent values

// Bank Name length not checked on gui input - but first 6 characters are saved correctly.

// Extended characters entered as bank names on radio are corrupted in Chirp

// Missing

// 50 SCV.WTH Set the VFO scan frequency range. BAND / ALL - NOT FOUND

// 49 SCM.WTH Set the memory scan frequency range. ALL / BAND - NOT FOUND

// Radio Questions

// Temp unit C/F not saved by radio, always goes back to C ?

// 44 RF SQL Adjusts the RF Squelch threshold level. OFF / S1 - S9? Default is OFF - Based on RF strength - for AM? How

// is this different from F, Monitor, Dial Squelch?

// Password setting on radio allows letters (DTMF), but letters cannot be entered at the radio's password prompt?

// 49 SCM.WTH Set the memory scan frequency range. ALL / BAND Defaults to ALL Not Band as stated in the manual.
