Lat: 34.27 Deg Sth\u00a0 Long: 150.94 Deg East<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The repeater consists of a 2 Metre Transceiver, followed by a transverter and a 25W p.a.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The memory of the&nbsp; simplex controller is programmed to function for a period of 150 seconds (2 minutes 30 seconds).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Operation of the Beacon:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Approximately every 10 minutes a CW ID will be transmitted. Part of the CW is dynamic. There are two values which are actively monitoring the repeater on site.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first is the Temperature inside the cabinet in degree Celsius The second is the system voltage at the repeater site.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CW message is structured as follows:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">VK2RMP experimental beacon test<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">QF55LR TEMP XX.X Deg.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SYSTEM VOLTS XX.X<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During the Beacon operation the Simple section will not operate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The beacon will not transmit while the simplex repeater operation is in progress and will wait until the simplex process is complete.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Operation Procedure of Repeater:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is recommended you wait for at least 10 seconds or press your PTT once for a short test, if a tail and beep comes back to you, your good to go.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If not, it may be that your signal is not getting in OR someone is using it on the input that you cannot hear.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pressing the PTT quickly to see if it responds (similar to a duplex repeater tail) will not interfere with someone else\u2019s transmission, as long as the PTT is quick, and not multiple times, this could be annoying for someone trying to record.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Summary :<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One quick one second PTT should give you a Tail and a roger beep. If not someone is using the repeater OR your signal is not been received by the beacon.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If there was no response it may be good to wait for at least 150 seconds (2 minutes 30 seconds) to see if the unit was in use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When transmitting, press the PTT button for about 1 second before speaking or transmitting data or pictures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reason for this is to stop any clipping at the start of the transmission. The repeater has a 0.5 second noise suppression timer to avoid false triggering.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No CTCSS is required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;Release the PTT and there is a one second delay before the recording stops and the current reception cycle is terminated. This is to allow for short signal drop offs during your over. Without this timer, a signal drop off may prematurely terminate your over and begin re-transmitting what you have just transmitted, whilst you are still recording.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After a 1 second delay the repeater will&nbsp;&nbsp; re-transmit your over. When the repeater has concluded your transmission you will hear an audible \u2018Rodger Beep\u2019.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If after the Roger Beep, there is no response, you may commence the next transmission. If you do not hear the \u2018Rodger Beep\u201d wait until you do.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Please make the transmission long enough to finish the job and short enough not to cause any others to be impatient.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Remember to be patient-including hearing the \u201cRoger beep\u201d to avoid any difficulties.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When transmitting data modes such as RTTY or SSTV, ensure the transmission DOESN\u2019T exceed the 150 second (2 minutes 30 seconds) , because if you do, the signal will be unintelligible and fail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Please pass this information onto your clubs and friends.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Illawarra Amateur Radio Society Inc. also has an experimental simplex repeater operating on the 23cm band. 1296.850MHz FM At Maddens .
