Poland now on the 4 metre band
A new band, 70.1 - 70.3MHz, was officially released to radio amateurs in Poland at 00:00CET today. I have been prepared for this moment for the last 5 years, and was ready and waiting. I made radio contacts using morse code, voice and data; the latter being in FSK441 mode using meteor-scatter with Enrico, callsign IK0BZY, in Italy at a distance of 1295 kms, as can be seen in the partial screen capture from WSJT9.

Meteor scatter using the Quadrantids
The Quadrantids meteor shower, which appears to come from the direction of the old star constellation of Quadrans Muralis near the Pole Star, has just intersected with the earth, as it does every year on the 4th January. I used the ionised trails produced as individual meteors burnt up in the earth's atmosphere to reflect my 50MHz radio transmissions to make contact with other radio amateurs in Denmark, Slovenia, England and the Netherlands by exchanging short, ( for obvious reasons ), text messages with them. The data transmission mode is called WSJT/JT6M, and I used the 500 watt amplifier featured on 25th January and 12th May 2010.
The screen shot shows one of Dick's, ( callsign G1CWP ), signals which I received during my contact with him in West Sussex, in the UK at a distance of 1451kms from me. The burst of signal has the characteristic profile of having been reflected by a meteor trail with its steeply rising leading edge as the trail quickly forms and peaks in intensity, followed by a more gradually falling trailing edge as the intensity subsides until the event is over.
I try to participate in all the major meteor showers during the course of a year; Quadrantids ( January), Lyrids ( April ), Perseids ( August ), Orionids ( October ), Leonids ( November ) and Geminids ( December ).
