I have a Shari PiHat-4U. It’s my preference to receive a one second squelch tail when I stop transmitting into my Shari PiHat-4U.
If I select the node setting for 0 half / full duplex with no telemetry, I do not hear the courtesy tone beeping, but there’s no squelch tail heard when I stop transmitting. When I hear the squelch tail when I stop transmitting, it gives me the confidence that my node is working properly. With option zero, there’s no squelch tail, it’s just like simplex.
Is there a way to select option 1 half duplex with telemetry, but turn the volume of the telemetry beeping to zero volume. Then when I stop transmitting, I would hear only the squelch tail with no beeping.
The easiest way to do this, though you’ll have to be careful about timing, would probably be to use duplex=1, and create a silent tone definition for “remotetx” in rtp.conf where courtesy tones are defined. , and comment out the definition for linkunkeyct if you don’t want a CT to play when remote stations unkey, but you still want hang time.
A silent CT with no theoretical additional delay would look like this: remotetx=|t(0,0,0,0)
Alternatively, you could set your hang time to 100 ms, define a 900 ms silent CT, then comment out the unlinkct definition. This will still give you a roughly 1 second hang time (will actually be a little more if you have the tail tone enabled on your SHARI) when you unkey, but will allow you to key up faster between transmissions from remote users on whatever node you are connected to. Realistically, if you have the tail tone enabled, and you want exactly 1 second of hang time, you should leave about 300 ms for overhead, as the 59 hz tone (or whatever it is) transmits for about 300 ms.
the radio transmits .
If you want to generate a 900 ms silent CT every time you unkey your radio, it would look like this. remotect=|t(0,0,900,0)
Sorry for the long delay to respond! I was able to silence the courtesy beeping for remote stations by commenting out the “linkunkeyct” line in the rpt.conf file. On remote stations, I have the one second hang time and no courtesy beeping heard on my Yaesu FT-5DR, which is exactly what I wanted.
However, I am not able to silence the courtesy beep that I hear coming from my Shari PiHat-4U when I unkey my Yaesu FT-5DR. I’m using duplex mode 1 on my Shari PiHat-4U.
I tried changing the remotetx line to:
remotetx=|t(0,0,0,0)
In addition, I changed the “remotect”’line to:
remotect=|t(0,0,900,0)
My goal is to have the one second hang time with no courtesy beep heard from my Shari PiHat-4U when in unkey my Yaesu FT-5DR.
