(unless it's while you are overriding someone else's signal) Please DO NOT transmit to SO-50 without a CTCSS tone of 67.0 Hz as you can and likely will CAUSE QRM. There are a number of terrestrial stations now (cross band repeaters, remote bases, etc.) that transmit on the SO-50 2m uplink without a tone and cause considerable QRM problems. Their strong signals 'collide' with stations trying to talk through SO-50 and it results in at most a squealing crash of signals, but more than likely nothing getting repeated at all. (Sometimes the 'dead air' on SO-50 is because of either this or because too many ops are trying to transmit at once... no one clearly gets through and the tone is not heard by the receiver; SO, it doesn't key up the downlink.) Without the tone, we cannot hear these QRMing stations when they 'transmit in the clear' in order to catch a callsign or a location.\n\n\nJust to be clear... this is the case with SO-50... AO-85, AO-91 and AO-92 are different.\n\n\nThanks & 73, Kevin N4UFO\n", "attachments": [] }
