User guide to start-up #ardop #pat-mail #direwolf

 

I am about a year in to using? RPi's.? Very new to Linux.? I have been wanting and trying to understand the whole set-up and steps of getting connected.? I am not using rig control and want to connect to local VHF nodes/gateways. However, i am at a loss.? I have tried many times unsuccessfully and have just walked away.? I am determined to learn how to do this.? Any help is appreciated.? I would like to create a step by step list of how to connect and send, etc.
 

For 2M Winlink connections, you will need the following installed at a minimum:
direwolf
ax25
pat
pat menu

For HF ARDOP Winlink connections, you will also need:
ARDOP
ARDOP GUI

All of the above can be installed via Build a Pi. Before we can get into more details about configuration, which radio and sound card are you using?

Hi Jason,
So, I am using a Yeasu FT-8800 for 2m and IC-7300 for HF.
I can receive packet info on the APRS frequency on my 2m with pat http and direwolf running.

For 2m, I open Direwolf and terminal window with pat http, then I go to browser and open localhost:8080
I don't know if I have a port number misrepresented somewhere.? I try to send using ax25 but it will not connect.
I will double check that I have AX25 installed.

For HF, I open ARDOPC and ARDOP GUI, I open terminal window and pat http.
Open browser and localhost:8080
I try to send using ARDOP, but it does not engage the radio.? I think I may have port number or something not correct for the Pi to talk to the radio.
FLDigi works just fine on the HF side.

I know it is going to be something simple that I am overlooking.

Thanks in advance.
 

I have no experience with the 8800 but PTT may be the issue. Which sound card are you using? If it's the Signalink, then the Signalink will handle the PTT for you as it has a built in VOX circuit.

For the 7300, you probably need to configure ARDOP PTT in the Pat conf file. Did you use Build a Pi for this build? If so, you can use Pat Menu to enable PTT for ARDOP. It is under Manage Pat Winlink->Set ARDOP PTT

I am using a SignaLink for the 2m.? I've checked all connections; disconnected and reconnected, cycled power, rebooted, etc.

Here is pat configure settings, beginning below my log-in information.? I am not using any rig control.? I am manually adjusting the frequency as needed.
I have checked the Direwolf configuration and everything appears to match with what I get when running arecord -l.

With the signalink, it is probably not a settings issue. More than likely it is an audio issue where you are not getting enough audio out of the pi to trigger the VOX on the signalink. Run this command
alsamixer
use the F6 key to cycle between sound cards until you find the one with "codec" in the name. Turn the volume to max and see if the signalink will TX. You will probably need to adjust this once you get the PTT working to set the ALC on the radio correctly.

I got frustrated by the whole process.? I'm trying to teach this old dog new tricks by using Linux.
Anyway, I did a complete update and reinstall of BAP and low and behold, I was able to get connected to PatWinlink.
I did a happy dance.

Thanks, Jason, for all the help!!!
