Then there's the issue of uplink \ninterference. If you have a keen ear, it is possible to tell by \nsubtle differences in the audio whether the signal is on the uplink \nor downlink, especially when you're running headphones. Similarly, \nit's also possible to tell if you are experiencing downlink problems \nor if the other station is not making the uplink, if you know what to \nlisten for (without looking at the S meter).\n\nThe above (except for Doppler shift, of course) also apply to \nterrestrial repeaters.\n\n73 de VK3JED\nhttp://vkradio.com\n\n", "attachments": [] }
