| Operation on VHF and Above |
| My main interest 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 in this wonderful hobby of ours. EQUIPMENT ON THE HIGHER BANDS: Presently I operate from home on all bands from 50MHz - 1296 MHz for terrestrial work and on EME, I am QRV from 144MHz through to 10 GHz. During the "troppo season" I can go portable with all bands to 47 GHz. |
