Our on-the-air dates are April 24 – April 29, 2015 — GMT. We begin Friday April 24 at 0000 GMT (Thursday evening 1900 CDT local time). We plan to operate several bands and modes. During local daytime we plan to operate on 20 meter SSB and during local evening on 40 meter SSB. We will probably also try other bands and modes, based on band conditions and operator interest.
