Here is the logging line for CQ WW, with W3LPL typed

- This is QSO #646
- If logged, W3LPL will be a country mult (C), and a zone mult (Z)
- This will be our third (3) QSO with W3LPL
- The received report defaults to 599
- The zone previously logged (5) is pre-filled
- Our data entry mode is OVR, and mode is CW
- The band/mult analysis shows that -
- W3LPL has been worked on 10 and 20m
- He is needed on 15m, but will not be a mult on that band
- He is needed on 80 and 160m, and would be a double mult on both bands

To do well in IOTA, you must work island stations
because they're worth many times more than other QSOs.
For the first fourteen years of the IOTA contest, from
1993 to 2006 inclusive, SD was the leading logger. Here are
sets the standard for instantly showing your band/mode
status for island stations, for highlighting multiplier slots,
and for ease of data entry of island references.
Other loggers can't do this! IOTA is special,
it needs the special features that only SD offers.

callsign letters, and
give you a real-time analysis of IOTA islands (if any)
worked and wanted for that country or call-area - for the
current band and mode. When the country is an IOTA island
with a single reference, SD auto-fills the reference.
gives you a worked/wanted analysis for all bands and
modes when you type an IOTA reference in the callsign
field - there's no need to touch another key or remember
function keys or multiple keystrokes.
