A tip from a yahoo radio group for those of you with radios that have 5 tone encode but no 1750 Hz tone burst
Kudos to "Dave" for his original posting of this tipHi possibly a good number of this group may know about getting a toneburst to open repeaters but I have come across some who don't so this may be useful.By using the digit 8 in the 5 tone selective call this gives a tone of 1747hz which is close enough to open repeaters.All you have to do is to program your radio to use sell call on repeater channels but you must have the facility to open the channel on press of the ptt or the send button because when a radio is set to use sell call the receiver is muted.You will need to set the tone time to 500ms.You will also need to check wich tone system your radio programmer has as different systems use different frequencies.The systems that you can use are CCIR or EEA.
hope it helps someone
