Once I have the satellite, I can follow the signal \nby ear (being a foxhunter helps ;) ), so then I can use one hand to \nwork the antenna, one hand to work the radio and monitor \ncontinuously, so I can make adjustments on the fly (something I tend \nto do \"naturally\" even when just ragchewing on the local \nrepeater). I've found it more efficient to adjust the antenna by ear \nthan to consult az/el tables. The ultimate computer control - the \none between one's ears. ;)\n\nWith practice, it's even possible to discriminate between uplink and \ndownlink fades on FM birds (works for terrestrial repeaters as well \ntoo!), because there are subtle differences in the (relatively, given \nthe limited audio bandwidth) high frequency content of the noise \nduring fades, and adjust the antenna accordingly, even if the \nuplinking station is noisy. And for those who can walk and chew gum \n(or talk and swing beams) at the same time, you can do it while \nyou're transmitting as well, if you have a full duplex setup.:)\n\n73 de VK3JED\nhttp://vkradio.com\n\n", "attachments": [] }
