This post shows the step by step process of decoding a Maidenhead locator code to calculate the latitude and longitude at the centre of a grid square. I have used this calculation in logging software I have been continuously developing the last three years.
Tonight I took part in UKAC contest (AR category) using my Yaesu FT-736R transceiver (25w), EA270ZB13 2m / 70cm Yagi made by EAntenna. The antenna is 5 elements on 2m (10.8 dBi) and 8 elements on 70cm (11 dBi).
With the mast at full height, my antenna is 171ft ASL.
