End of day 1 of #RailwaysOnTheAir. We've been operating #GB0SDR from the Somerset and Dorset Railway Heritage Trust at Midsomer Norton South Station. Congratulations to Kenneth #M7MYU for handling his first on-air pileup. We'll be back tomorrow, when it's gala day for the S&D, so look out for us.

Yay! more #SSTV from the #ISS Now to determine how civilised the orbital pass times are over #IO81QK Rumour is that @g7kna.co.uk is going to try using #GPredict with #GQRX to provide Doppler Shift to a #SDRPlay RSP 1A SDR which sounds like fun

Congratulations to G0FBB, Windmill Hill Contest Group, and G3PYE, Camb-Hams, for being the only 2 groups that we have worked in all of the past 15 years of participating in VHF Field Day during which time we have worked 2,023 contacts of which 1,135 are unique
