Bulletin listed: 29-Nov-2014 00:00 until 31-Dec-2014 23:59 Title: 01-Dec-2014 - - Tone 100 System - - The Toronto ARES Group is proposing a new Amateur Radio simplex linking program with the name “Tone 100 System”. This is a year 2015 project. Please be patient. Such projects take a lot of time to catch on. Your continued participation is important. - The program works on the mutual understanding that the frequencies 146.520 MHz and 446.000 MHz are recognized as National Calling frequencies throughout North America. 223.500 Mhz will be dealt with later. - Frequencies 146.550 MHz, 146. 580 MHz and 446.025 Mhz are recognized as working frequencies. The program will also promote that each region list one or two additional local simplex frequencies using a 100.0 Hz tone in each band in addition to the nationally recognized frequencies. - What will distinguish the ‘Tone 100 System’ activity from all other on air activity is that all participants will at all times transmit the sub audible tone ‘100.0 Hz’ (Tone Squelch) when active with another participating station on any of the Tone 100 System designated frequencies. - When loading Tone 100 frequencies into memories, stations are requested to also load adjacent memories with only the Transmit (100 Hz) tone. This will permit monitoring frequencies for any and all activity that may be on a channel. A basic rule will be to not transmit over any activity already using a channel. Should the main calling channel 146.520 Mhz. be busy with active activity, 146.550 Mhz. becomes the primary call channel, etc. - All stations transmitting the 100.0 Hz tone, when first turning on their radios onto 146.520 Mhz. will indicate their presence and wait for a response from a monitoring station also transmitting the 100.0 Hz tone. The stations then have 60 seconds to switch to a working channel. The stations also have the option to make no further transmissions beyond 60 seconds and to continue to monitor the calling channel especially when one of the stations is a mobile station. - The following chart is representative of your memory line up as a participant of the ‘Tone 100 System’ in the Greater Toronto District. - These memories are not to replace those memories currently in your radio using the Toronto area 103.5 Hz tone. - If this becomes an active process in the GTA, we hope that other Ontario areas go along and also adopt the ‘Tone 100 System’ so this activity becomes Province wide. - Please load the following lineup into your base and mobile radios. - When starting operation, announce your presence on 146.520 MHz. - Simply say your call sign 2 or 3 times followed by the words ‘On Frequency With Tone 100 or words to that effect. - When responded to, be prepared to go to a listed ‘tone squelch’ working frequency within 60 seconds or after a hello and good bye to inform that you will stay on 146.520 Mhz. - - Channel No. - Frequency – Tone. x x 1 - 146.520 - Tr 100.0 - Rcv 0.0 x x 2 - 146.520 - Tr 100.0 - Rcv 100.0 x x 3 - 146.550 - Tr 100.0 - Rcv 0.0 x x 4 - 146.550 - Tr 100.0 - Rcv 100.0 x x 5 - 146.580 - Tr 100.0 - Rcv 0.0 x x 6 - 146.580 - Tr 100.0 - Rcv 100.0 x x 7 - 146.460 - Tr 100.0 - Rcv 0.0 x x 8 - 146.460 - Tr 100.0 - Rcv 100.0 x x 9 - 147.405 - Tr 100.0 - Rcv 0.0 x x 10 - 147.405 - Tr 100.0 - Rcv 100.0 x x 11 - 446.000 - Tr 100.0 - Rcv 0.0 x x 12 - 446.000 - Tr 100.0 - Rcv 100.0 x x 13 - 446.025 - Tr 100.0 - Rcv 0.0 x x 14 - 446.025 - Tr 100.0 - Rcv 100.0 Please send your suggestions to Joe at [email protected] or via the Toronto ARES message board or on one of the nets.
