PACCdigi Software

In the 2024 contest everybody can work everybody worldwide. There are three different classes available: FT4/FT8 only, RTTY only and MIX if FT4/FT8 as well as RTTY are used.
SWL stations can take part only in RTTY.

Please read the “rules”, available on this page, before the contest.

For the N1MM users in the contest is a User Defined Contest file (UDC-file) available.

MMTTY has been chosen as preferred RTTY software. Please look under “N1MM” and “MMTTY” for further information.

WSJT_X software can also be loaded in N1MM. In that configuration N1MM is only used for the logging function. Look at “WSTJ_X” for the information.

FT8 RTTY Roundup

Both the FT8 and FT4 modes can be used in the contest. Both modes will be seen as the same digital mode. So if a station is worked in FT4 and FT8 the second qso will be treated as DUPE. Different frequencies are used for FT8 in the PACCdigi contest. It is useful to put those frequencies in the list so that WSJT_X does not always jump back to the standard FT8 frequency per band.

Use at least the 2.6.0 GA or a newer version of WSJT_X for this contest!
