Installation packages for Windows, Linux, and macOS are near the bottom of the page. To participate you must use WSJT-X version 2.0.0-rc3. Use dial frequency 7.078 kHz, moving up in 2 kHz increments if interference is too great. Short “Practice Contest” Set for ARRL RTTY Roundup Participants Planning to Use FT8Ī 1-hour “practice contest” will be held next week on Wednesday, 24th October 2018, 0200 –0300 UTC (Thursday 25th October 2018, in North American time zones). The FT8 users’ groups and online discussions will offer information about alternate carrier frequencies for FT8. FT8 users also are advised to spread out to help increase decoding and contact success.

The Contest Branch is encouraging all participants to make the use of FT8 a success in RTTY Roundup by managing frequency selection and being patient with new contest operators. Logs designating all contacts with “RY” will be accepted, however.
#ARRL RTTY ROUNDUP RULES SOFTWARE#
Logging software developers have been advised that “DG” will be accepted as a mode abbreviation for all digital QSOs other than RTTY, which will continue to be designated as “RY.” This will assist the ARRL Contest Branch in distinguishing RTTY from other digital-mode contacts in order to assess the popularity of each. Since ARRL contest rules regarding spotting assistance prohibit the use of “automated, multi-channel decoders” by Single-Operator entrants, stations using software that decodes more than one FT8 signal at a time will have to enter as Single-Operator Unlimited or as Multioperator, just as PSK participants have had to do in the past when using fldigi or DigiPan software. Neither is FT8’s Fox-and-Hounds mode each contact must be carried out in a one-to-one mode, manually accepting/logging each contact. No unattended operation, including QSO/macro automations, will be allowed. Participants must use WSJT-X version 2.0 or later to ensure they are able to transmit and receive the exchange messages the event requires. Some limitations will apply to FT8 entrants.
