ATV

摘要

There are various 'hot-spots' of ATV activity around the country and one of those is North Wales. Even though the terrain is anything but kind to UHF and microwave operation, up to 20 stations are active using the two repeaters GB3GW and GB3TM. Brian Davies, GW4KAZ, has built a very neat mobile installation, finding sites where he can work through both repeaters using only 800mW output to an Alford slot antenna. Brian has modified a Maspro satellite receiver for 24cm 12V operation. This receiver is particularly popular with ATV enthusiasts as it has switchable IF bandwidths and seems particularly sensitive. A 5in monitor serves for viewing incoming signals and monitoring his transmissions. The passenger seat headrest is a steady support for the miniature video camera.
