You can put up large antennas and run big power. There will be stations in the eastern USA that have real receive capabilities on the VLF band. many guys over here can hear SAQ and other EU VLF stations already. It might be a long shot, but if you do get a signal across the pond, imagine the feeling you will get from that? Damn cool. The VLF band is in it's very early experimental stages today. With the great interest now, we may see regular two way communications down there in the future. Look at the LF & MF bands today. Everyone started out with tiny signals and dreams. Now we can work across the pond on both bands. The VLF band could be the next dream come true. Build the VLF station. Show others that it can be done. Others will follow along and build their own VLF stations. Share all the technical details so others can use that to develop their station successfully. Don't be discouraged if other guys don't build huge high powered stations. Not everyone has the time, money & land to do so. There will always be QRO & QRP stations. Enjoy working both types. The QRP stations will be the challenge for your receive capabilities. hi hi... There is getting to be a lot of interest in the VLF band over here. Maybe some day we can work across the pond to you guys? Baby steps first...
