Martin G8OFA has been using 2m MS (meteor scatter) this year and has worked some impressive DX as the photo shows. The MS QSOs are shown as squares with bold outlines. As you can see, these are far into continental Europe. Such contacts would be rare on 2m by tropo and QTH, power and antennas would be important.
MS is available at any time (random MS) but is best in showers. It works at any time in the solar cycle. QTH is less important. On 6m, pings tend to be longer, although antenna elements are bigger.
