This year’s IOTA Contest takes place on Saturday 27th – Sunday 28th July 2024 from 1200 – 1200 UTC. Haoyuan 9V1HY is coordinating the Singapore entry, which will likely happen from Pulau Ubin or St John’s Island, likely travelling out on the Saturday morning, getting set up ready to start our time afternoon, then operating through the night before wrapping up on Sunday morning.
Anyone interested contact 9V1HY via telegram. For background on the contest, check the RSGB as it coordinates the event. There is more information about IOTA’s long term year round role and activities on that organization’s website.
