Pete, I always liked something like 400 Hz for impolite IDs that would need to be played under users, and 500 Hz or higher for IDs that would stand alone. Many radios have a peak in their acoustics between 650 Hz and 1.5 KHz, so audio tones in that range will sound really loud on some radios.
As has been mentioned elsewhere, the 20 WPM limit in the US only applies to a device used exclusively for ID, a loophole that allows you to send at whatever speed you want with a modern repeater controller. But I've never understood the point in trying to "bury" the ID or "get it over with." It's not like it prevents anyone from continuing the conversation. I've always used 20 WPM or less. If you need to hide the ID on a linking system, there are notching and other techniques which can be employed. On a local repeater's output, just send standlone IDs without PL encode, and users have an option to hear them or not. 73, Paul, AE4KR ----- Original Message ----- From: Peter Summerhawk To: [email protected] Sent: Saturday, February 14, 2009 11:10 PM Subject: [Repeater-Builder] Need some advice- Tone and ID for repeater Morning Crew, I need some suggestions on what tone frequency people are using for the ID on their repeater as well as speed for the ID. I am using a repeater controller that I can adjust the frequency and speed of the system. I want to use something that can be heard but don't want it to be to high so they users go deaf or have the speed to fast as its all a blur in the id. Suggestions? Thanks Peter Summerhawk-N0WRE
