I think we have an interesting (%) hole here. The web page for submitting a chase offers DATA only. The code for parsing csv files allows a variety of modes and collapses them down to the valid modes : AM, CW, DATA, FM, OTHER or SSB
USB LSB J3E are converted to SSB
PSK31 RTTY are converted to DATA
F3E is converted to FM
A1A is converted to AM
Probably PSK31 should be a variety of digimodes and just the PSK bit should be valid allowing PSK31, PSK63, PSK250R etc. Similarly for MFSK etc. etc.
(%) for assorted definitions of interesting!
