Re: Reverse Burst CTCSS/DCS


 

¿ªÔÆÌåÓý

True enough,and so it is.


I found something in the MD-380 CPS that might have been the culprit--the "Admit criteria" was set to "Always," so I changed it to "Correct CTCSS/DCS" but it made no difference.


I take it "QT reverse" should be 180? I assume that's degrees, as in 180¡ã out of phase?


I can't think of anything else to change, except maybe quelch from normal to tight.

I'm going to state the obvious, and it may sound snarky, but it's not meant to be. If the Shari is set to send a DCS tone and the radios respond, then I turn the Shari DCS off and the radios don't break squelch, then I obviously have the radios programmed correctly. Both my radios are set to DCS value 411 (411N on the Shari). When my node is off the air, I can use one radio to talk to the other, and it's totally tailless. I can never remember whether the value for reverse-burst ON is 0 or 1, but I *can* tell you that either setting produces the same result--a loud crashy tail. Also, I think I can reasonably assume that the setting for reverse burst on the Shari is enabled when the time the carrier stays on after the courtesy tone is longer. Sure wish I could figure this out, because I *know* it's supposed to work correctly.

I have the reverse burst turned on and I use a MD-380, a Baoefeng UV-5B and a Baoefeng BF-F8+.? I don¡¯t get a squelch tail on any of them.? You might to run the shari-pixx-prog again and make sure the reverse burst was actually turned on.? Also might want to check that the receive ctscss was programmed into your radios as well. If they¡¯re carrier squelched that can cause a squelch crash too.?

I'm one of these people--I'm sure you know at least ten--who don't like

squelch crashes and who think reverse-burst on CTCSS or DCS is the way

to eliminate them. Therefore, imagine my surprise when, even though both

my VHF and UHF Shari's are set to produce one, none of my radios act

like there is one. I've been told by many people that it's my radios'

fault, that they just don't process reverse burst properly. This is

demonstrably not correct. I can use one radio to talk to the other, and

when I un-key, the receiving radio snaps off immediately totally without

a tail. I listen to folk walking around with radios in my apartment

building, and when they un-key, same thing--the audio just goes away

without a hint of a squelch tail. So then, what is happening on the

Shari transmision that causes every one of my radios--two Tytera 380'

(one MD, one UV-MD), a scanner, a Kenwood TM-D700, and a pair of Bao

Feng 888's--to ignore the reverse-burst and give me a loud obnoxious

crash when my Shari's un-key, yet they all behave correctly when talking

to each other?
