Baud Rate For APRS #aprs


 

I am running APRSIS32 on a Windows 11 PC with a TinyTrak4 TNC connected to my Yeasu FT857d radio.? The TT4 I know is properly configured - I used it years ago.? The software needs to know the port and gives me a choice of 3 or 4, and a baud rate.? Where do I find the baud rate to use?? And how do I know which port to use?? Thanks - I am setting up an iGate in a rural area with no other iGates within reasonable distances.? Thanks!

I think APRS works on either 1200 or 9600 baud. But it's been awhile since I played with APRS.

You will need to go into Device Manager on your PC to determine what COM port you are connected to. If it is not clear while looking at it, disconnect the USB cable and see which one goes away. Plug the USB back in and see which one shows up. That will give you the COM port for the software. The default baud for the TT4 is 19200, so unless you changed it for some reason, that should work.

Mine is 1200 on external signalink tnc on 857 & 1200 on kenwood ?D710 internal ?tnc.?

It would seem reasonable that 1200 is a very good starting point.?

Good luck.?

I think he is talking about the baud rate from the computer to the TT4, not the over the air rate, which is pretty much always 1200 on 2m and may be 1200 or 9600 on 70cm.

I see.? Missed that critical point.

Thank you for the clarification.

Hi Stan,

?

That’s the radio side, not the serial port side.

When I go to Device Manager I show a com 4 and 5.? Both are listed as 9600 baud.? When I go to APRS-IS software it shows com 3 and com 4, so I assume com 4 must be it.? I set Device to com 4 and 9600 baud.? The RF baud rate is greyed out and is 1200 baud.? I assume that is what the radio must be at so I set the Packet rate at 1200 baud.

Currently I can hear APRS traffic on the radio.? When that happens I see the lights flashing on the TT4 but nothing is making it to APRS-IS or ? if I go out to my car and beacon tx on my Yeasu FTM400-XDR.

What am I missing?? Also, what mode does the radio need to be in?? I currently have it in FM mode.? Does it need to be in Packet mode?? Thanks for the discussion!

Hi all , are 2 different things :?the baud rate from the computer to the?TT4 and baud rate?over the air rate, some of you responded for the second - always 1200 on 2m , correct , but I guess the question if for first - can be any baud rate depending on what is configured TT4 ( 19200 defailt ) and must match with computer port rate.

While you are looking at Device Manager, unlpug the USB cable from the TT4. One of those COM ports should go away. Plug the USB cable back in and it should come back. That will verify which one is correct.

Ignore the RF baud rate, that will always be 1200. There should be a baud rate selection associated with the COM port choice. Start with 19200 (default for TT4). If you are seeing lights blinking on the TT4 corresponding with APRS traffic heard, then your radio and TT4 should be okay. It's just the computer=TT4 connection you need to work on.
