Dean from Portsmouth here. Great site and software, congratulations to the author/team. I would like to request access to submit data to the map automatically from my GMC-320+V4 (ver 4.21) with M4011 tube. I am located right next to Gunwharf Quays and the Portsmouth Dockyard in Hampshire, perfect for keeping a eye on the comings and goings of the subs and carriers. Worrying times with Fukushima, & mysterious Iodine 131 spikes over Europe. I'm keen to learn where people buy their calibration sources from. Would also be great to hear from any other fellow radio amateurs nearby.
