Radio units arrived

MTX2The radio modules we’ll be using on the M2R radio boards arrived from Radiometrix today. They’re generously sponsoring Martlet 2 with these radios, thanks! We’ve been using their radios for many years now, starting with the venerable NTX2 for some early high altitude balloon payloads, and they’ve always performed perfectly. We’re excited to try out these very new MTX2 modules — they are much smaller than the NTX2 and should have excellent frequency stability thanks to a temperature compensated crystal, plus they are in-flight frequency reprogrammable in case we find frequency clashes in the field.
