Master III 2175Hz Debounce

[justanotherguy59301]

I apologize if this has been discussed somewhere else, I did try searching relevant terms.

We are using Tone Control on our area base radio, with 4 wire tone remotes. Occasionally on the line there is a popping sound that comes from the backhaul(VOIP). When the tone remote is keying the radio and one of the occasional pops occurs, the radio will sense a "NO TONE" and the radio will stop transmitting.

It looks like the radio has a function specifically for this, in the Configure Radio>Remote Control section. The 2175 debounce timer according to the help menu should delay the radio from executing a "NO TONE" function for a selected amount of time if it senses a loss of the 2175 hold Tone. I have set that to the max(2.5 seconds), for testing purposes, but the radio still seems to stop transmitting as soon as the hold tone goes away, In my mind the radio should remain keyed for an additional 2.5 seconds after the tone remote ptt is released. I have also tried to simulate the popping by using a momentary push button to short the TX pair of the tone remote, the radio does decode a No tone followed by a return of the 2175 hold tone when I try testing it. Neither the debounce nor adding a timer before the stop remote PTT function in the No Tone table, seems to achieve the desired effect.

Is there something I'm missing (I usually assume there is).

Solved;

The 2175 debounce timer works with the "2175hz Off" function instead of the "No Tone" function. I Null'd the "No Tone" functions and added the "Stop, Remote PTT, Start, Enable Scan" to the "2175hz Off" list and the 2175hz debounce timer works as advertised.

I also had to enable the "HOLD 2175" in the Remote Configuration screen. This is why I Null'd the "no tone" list, the help screen discusses these two functions can be conflicting.

how do you have the audio IP'd over to the radio? im looking to set something like this up?

We are using TCCommunications TC-3846-6 at our Office Locations and a TC-3846-6 with a TC-8926 at our Base locations. The 3846-6 is a 4 port 4-wire analog over IP device that allows you to point each port at different targets. they also have a 2-wire version if that is what your system requires. We have multiple offices controlling multiple bases for a large area, so these work well for our needs. The 8926 is a Hoot-N-Hollar device that we have at our base locations, it takes all of the 4 wire circuits from our offices, gives everything a nice 600 Ohm load, and prevents echoing due to different latencies in the IP network.

If your IP network is stable and low latency the 8926 may not be necessary, but I also like the fact that I can plug in several devices of varying impedance and the radio always sees a clean 600 ohm load, as does the other equipment.
