TX7M is the callsign of another big ham radio dx-pedition, this one going to the Marquesas Islands, out in the Pacific Ocean near Tahiti. I've worked them on 8 bands (see chart at right) using CW (morse code).
This is a major effort is being put on by a group of Russian radio operators.
In recent years it's been difficult to work foreign stations on the higher bands (10, 12 and 15 meters) due to a lack of sunspots. With the 11 year solar cycle coming into full bloom, these bands are now open and stations all over the world can be contacted.
The photo shows one of their antennas used on the 10 meter band hanging from some palm trees.
