SUMMARY:IRTS SSB Field Day
DESCRIPTION:Sponsor: IRTS\nModes: SSB\nBands: 80m\, 40m\, 20m\, 15m\, 10m\n
 Band note: 3.5\, 7\, 14\, 21 and 28 MHz -- no 160 m\, unlike the CW field 
 day.\nDuration: 24h\nExchange: A signal report and a serial number startin
 g at 001.\nEligibility: Entry limited to EI. K stations may be worked but 
 cannot submit an entry.\nLogs due: 2026-09-20\nNote: IT FALLS ON THE SAME 
 WEEKEND AS RSGB'S\, AND THAT IS NOT A COINCIDENCE. Both societies run thei
 r leg of the IARU Region 1 Field Day: RSGB's National Field Day is the fir
 st Saturday of June and IRTS's CW Field Day is the first full weekend\, an
 d the same pairing repeats in September. They are separate contests with s
 eparate rules\, separate logs and separate results -- which is why both ar
 e here rather than one.\n\nThe pairing also settles what the IARU Region 1
  Field Day IS: a framework each member society runs its own contest inside
 \, not a contest IARU publishes rules for. DARC lists it on their calendar
  and says it is IARU's\; UBA lists it too\; IARU Region 1's own site publi
 shes rules for the HF Championship and nothing else. Nobody claims it\, so
  there is nothing to encode under IARU's name.\n\nENTRY IS EI ONLY AND POR
 TABLE ONLY: 'Any individual or group operating in EI complying with Rule 3
 .6 of the General Rules and operating portable on a site'. Stations elsewh
 ere may be worked but cannot enter.\n\nTwo differences from the CW field d
 ay\, both IRTS's own and both matching RSGB's pair exactly: it starts at 1
 300 rather than 1500\, and it drops 160 m.\nRules: https://www.irts.ie/cgi
