This site is dedicated to the operation and history of amateur radio station N7BHC. Most of the data pertains to VHF DX operation,  propagation, and beacons The focus is on tropospheric ducting.

I was first licensed as ZS2BI in South Africa in the late 70s. Upon emigrating to the USA in 1978, I was first licensed as KA4DRA. My callsign changed to N7BHC when I moved to Utah. You can read more of my ham radio history on these pages.

In 2008, my focus is on trans-oceanic VHF ducting. A number of research projects and operatiosn are in process to expand the global use of this mode.
