General Technical Courtesy Tone (Telemetry) Question

Hello all
As stated in the Topic, this is just a general question, mainly to the developers or whoever else may be able to answer the question. So I commented telemetry = telemetry in the main settings of rpt.conf, deleted the entire Telemetry Stanza with the ct1, ct2.... settings but left the "unlinkedct =" settings set, in my case using ct2. I am still getting the courtesy tone after receiver drops COS. I can also change to ct1 and get the original ct1 courtesy tone. Again everything is either deleted or commented out concerning CT's. Where is this setting coming from in order for the courtesy tone to still sound.

Thanks all

Harold, there are default values for settings not issued in conf.
Removing a setting from the config file may not do as you might expect.

Problem is we have never had a list of the default values with asl3.
And not every setting has a default value. Trial and error I guess.

Ok sounds good. I kinda figured there had to be some hard coded defaults, even though the settings are missing in the config file. All good.

Thanks for the info

Some history on courtesy tones:

I implemented the original courtesy tone code in app_rpt. At that time, we wanted to use courtesy tones which were heard on repeater systems in Southern California.

The courtesy tones in rpt.conf came from two types of repeater controllers:

  1. Advanced Computer Controls (ACC) RC series repeater controllers
  2. "Burgstaller" and Palomar Telecom RBC-700 controllers predominately used on private RF linked systems (examples: Cactus Intertie, Calnet).

Some of the courtesy tones are from the ACC series of controllers.

The courtesy tone you hear when you are linked and you kerchunk a repeater in transceive mode is two single tones one at 1633 Hz followed by a second at 1209 Hz. The courtesy tone you hear in monitor is just one tone at 1209 Hz. The function complete tone is two tones at 1000 Hz and signifies that a repeater function has been successfully interpreted and acted upon. These tone sequences came from the Burgstaller and Palomar Telecom repeater controllers mentioned above.
