During the first weekend of June, we’ll find the Seanet contest on the air, taking place between Saturday 12:00 UTC and Sunday 12:00 UTC on CW, phone and RTTY (by the way, Seanet stands for South East Asia Amateur Radio Network).Rules are simple: there are no single mode categories and the allowed bands are 80, 40, 20, 15 and 10 meters. It is suggested that activity should be centered around the following frequencies when possible, making it easier to find SEANET Stations:
CW: 3525, 7025, 14025, 21025, 28025.
SSB: 3540 (for Thailand), 3790, 7090, 14320, 21320, 28320.
RTTY as per international assignments.
Valid DXCC entities that you can work in this contest are: 4S, 4W, 8Q, 9M/DX0 (Spratly), 9M2, 9M6/8, 9N, 9V, A5, BS7, BV, BV9P,BY, DU, H4, HL/DS, HS/E2, JA, JD1/M, JD1/O, KH0, KH2, P2, P5, S2, T8, V6, V8, VK, VK9C, VK9X, VR2, VU, VU4, VU7, XU, XV/3W, XW, XX9, XY, YB, i.e., all entities in CQ zones 22, 24, 25, 26, 27, 28 and 29, including the sectors which may lie in other zones.
Another interesting one is the 10-10 International Contest. There’s also the Open Season PSK Contest: it takes place during a full 48 hours, only in the 10 meter band and only in BPSK31 mode. See rules here: http://www.ten-ten.org/oseason/oseason.html
Well, it’s June, the best month for sporadic-E on 50 MHz. So it is worth considering the UKSMG (UK Six Metre Group) contest from Saturday 13:00 UTC to Sunday 13:00 UTC. For details: http://uksmg.org/contest/rules.php.
As far as DXpeditions are concerned, for this weekend, the most significant operation is A5A, active from Bhutan until June 6.
