Operation on VHF - UHF - SHF +



One of my main interests in Amateur Radio is weak signal work on the bands above 30 MHz. Operating from home or "Hill-topping" on the Microwave bands provides a wonderful incentive for building gear.


In Summer the VHF and above bands "come alive" with "tropospheric" propogation. But they also come alive at other times such as during "Auroral" openings and during "Meteor Showers". There are many different modes of propogation above 30 MHz and they each provide a challenge and a rewarding experience.
