Today I sent out an email with details for a WSPR challenge in VK1 (ie. QF44jc to QF44qu). The challenge being who can send a WSPR packet the furthest, and who can receive a packet from furthest away. It's then also broken down into three categories according to power of transmitters (500mW and below, 5W and below, and more than 5W).
The challenge goes until Friday midnight (local time) and started this afternoon. It's early days yet, but it looks like as people come home tonight it's kicking off. 🙂
Oh, there's also a bonus challenge of who can receive the most VK1 stations.
