I was looking for a triple beep like the XTS portables do on a trunked system. Even though I would prefer that, I'm not that picky. Are the Sabers capable of a triple beep TPT, and if so, is it limited to only certain types of Sabers? And can you set it up for only certain frequencies or is it a radio-wide setting?
As far as I know, the "trick" of making the triple beep on any type of channel is with the HT1000. Possibly the MT2000. Since HT1000 RSS is used for the JT1000 and the VISAR, then I am sure those radios do it. It is a trick though. You tell the radio to send three DTMF ANI tones (aka 111) at Pre. You set them to about 25ms on, 25ms off. Then you change the side tone from the actual DTMF to 900Hz tone. So then it makes it sound like the Trunking Talk Permit. The three DTMF tones are sent, but since they are such a short duration, most radios filter it out if they have PL or DPL, and while testing, I have found DPL filters it a lot better.
I know many radios can do the constant tone when MDC is sent over Pre. But if set only to post, then there is no beep to let you know the radio is transmitting (that is how my Spectra is). I know some newer radios have a tone that is always sounded when the radio keys up, but i am pretty sure it isn't like the triple beep.
Does anyone know how to make the Spectra do some type of "transmit tone" that isn't constant or at least doesn't require a Pre MDC (I only use Post MDC).
Hope that helps!
