My closest gateway for WinLink is 17 miles away. ?If that goes down, the next is over-the-horizon. ?In all of Jacksonville, the largest city in the US by size, there are exactly three gateways. ?

We need more.

I've been emailing Mark at PiGate to see what the best way is to proceed using his product, and I keep getting confused between the email server piece and the actual gateway. ?He's being extremely helpful, andI look forward to continuing down a path with him.

Has anyone had experience building a gateway with a Pi? ?My setup I currently have available for a build:
Computer: Raspberry Pi (both 3 and 4)
Radio: FTM-100, FT-857 (will be buying a FT-2980 this week for the increased power-out)
TNC: MFJ-1270X "TNC-X"

My goal is simply to provide another gateway for people to use in my community.

Very respectfully, 73,

Grant / K4GDG

Both of the links provided are working at this end.

Shah -- good afternoon
I'm not next to my rig -- so I'll take some photos next time I'm in the shack.

However from memory:
1) Your Sabrent sounds to be connected correctly -- assuming of course you have 'input and output' cables in the correct ports?
2) If CAT control is working then nothing more to be done here (I'm assuming you can PTT over FLRIG as well?)
3) I'm always suspicious of end fed high impedance antennas as without a correct counterpoise they can be the cause of lots of RF effects on a rig's audio. Common mode currents need to be actively tamed. Don't assume it will work with every rig in the same way.
4) I'll take a note of my KX3 menu setup the next time I'm in the shack later today

Are you able ot get WSJT-X running correctly or are all applications that need audio input/output problematic?

Good morning.
You didn't give your name?

I'm running Build-a-pi + KX3 and Sabrent USB audio.

I'm not using signal link (Not sure why you need to run signal link?) I'm just using the USB CAT interface I bought to support CAT with my KX3 on my MAC)

I'm using FLRIG to interface the KX3 for CAT and PTT -- and that works fine.

I run my Pi 'headless' i.e. via a VNC from any of my devices (MAC, Windows 10 PC, IOS etc.,)

I've not had to document any of this, as its all pretty familiar to me -- but I can understand if you are not using this stuff every day, it might be a bit daunting.

I don't have recent experience using the Signal Link (I used one 15 years ago on my FT847) -- so I can't remember much about it.

The Sabrent is 'plug and play' with no drivers or settings -- other than to select it (Input and output) in the 'Audio' tab of WSJT-X
The KX3 USB Cat interface might need you to install the FTDI driver but that's it.

What information do you need?

There is also gpsmon -n -- an interesting program as well. Since I generally eschew GUI programs, I tend to use cgps -s and gpsmon -n as my go-to programs for checking the behavior.

The one thing I like about xgps is the graphical display of the sky view and satellites.

Have fun!

--

xgps or cgps are the ones I use. You can start both from the command line.

What program does everyone use to be able to see what satellites you are receiving?

Has anyone connected two radios via SignaLinks to one Pi?

Different VNC programs may not successfully negotiate the handshaking for encryption/authentication and/or screen resolution if left in a default configuration. (In my case they simply will not connect without changes.)

Has anyone tried 3.0.3 with FLRIG and a Yaesu 891? I have had one gentleman that can't get it working but I am unable to duplicate the issue here. Just curious if anyone else is having the same issue?
--

Kenneth, can you help me offline to setup a Signalink usb+ on my BAP 3.03?? KB3FN@...

I always do a headless start.? I copy image to SD card. Put two files in the root of the SD card as follows:
1.? ssh? ? ? ? ?This is just an empty file
2.? wpa_supplicant.conf? ? This file contains my network info as follows

The groups.io formatting of text is "killing me" ....anyways, it displays one thing and emails another...SO, please go to the groups.io website to read these instructions, so you are NOT adding extra spaces, lines, etc.

Double sigh.....

Hey all; I decided to install BAP 3.0.2 this past weekend on a well-tested Pi4b-4gB *without*
needing to plug-in a monitor, keyboard, or mouse OR even a network (ethernet) cable.

Here are the steps;


1 - FLASH AN SD-CARD WITH LATEST RASPIOS/RASPBIAN:

There is an interminable number of instructions on how to do this on the internet. I
used rpi-imager, and the default selection(s) on my Manjaro-Linux-aarch64-RPi4b
-8gB desktop. The sd-card was plugged into a sd-card-2-usb device. It showed up as
/dev/sda .


2 - ENABLE SSH LOGINS:

Add an empty file to the "first" (/boot) partition that is named ssh. This item is covered
in Jason's video;




3 - ENABLE FIRST LOGIN TO BE “WIRELESS”:

Add a simple text file called wpa_supplicant.conf to the /boot partition. Enter the
following text into the file. (** Be sure to substitute your network name and password
between the quotes AND leave the quotes marks and the lack of any indents, blank-lines.) :

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US
network={
ssid="Your-network-name/SSID"
psk="Your-network-password"
key_mgmt=WPA-PSK
}



4 - FIRST BOOT-UP:

Put the sd-card into your wireless RPi, apply power, and watch the blinking green led
while your new operating system boots up.

Use ssh on your regular "desktop" machine (which you probably used to create your
NEW RPi’s sd-card) to log into your RPi-headless-&-wireless machine. Something like
this from a command line should "do-it":

ssh pi@your-rpi-ip-address

NOTE: You will need to replace your-rpi-ip-address with the ip number your local
network router assigned to your new RPi AND, when prompted, the default password
is raspberry.


5 - ENABLE VNC:

RUN the following command:

sudo raspi-config

You will **need** to make changes TWO changes to the default setup. You
must enable the VNC server AND set the screen resolution to something other than
the default, I find setting it to 1024x768 to be a good selection to start with.

NOTE: The arrow, tab, and enter keys are used to navigate and select items and settings
in raspi-config. You will find the VNC server enable under item number 5 and the screen
resolution under item number 7.):

(OPTIONAL STEP: You can also use raspi-config to enlarge the /root partition. This will
also be located under item number 7.)

Reboot the system using this command:

sudo reboot

LOGIN again using ssh. Then execute the following;

sudo su
cd /root/.vnc/config.d
cp -a vncserver-x11 vncserver-x11.org
nano vncserver-x11

NEXT add the following to the file, saving the result and exiting nano using ctrl+x
followed by a y and finally the enter keys:

Encryption=PreferOff
Authentication=VncAuth
Password=e0fd0472492935da
IdleTimeout=0

THEN reboot the system using this command:

sudo reboot



6 - USING THE “HEADLESS AND WIRELESS” RPI:

LOGIN by starting up using your desktop's vnc client (in my case tigervnc). The login
is the RPi’s network ip-address and the password is foobar .

I am sure everything went well, so you will be greeted with a window containing a
“virtual-screen”. One or more “pop-ups” will (almost immediately) appear AND will offer
you the option to update and eventually reboot your system, which you SHOULD do !

NEXT, after you login again, you should spend some time and play around. Among
other things you should learn how to open a terminal window.? Mouse (left) click the
icon to the **right** of the Raspberry Pi icon. These icons are located in the top left
corner. The one for the terminal looks a bit like a terminal window would. Hi Hi.


7 – INSTALL AND USE BUILD-A-PI:

WHEN you are ready you can install Build-A-Pi (BAP) using this command from inside
of the terminal “window” (which you learned how to use in the step immediately above):




**** I want to thank Jason - KM4ACK,? Mitch - N7USU, and Jerry - N5RKE for their
feedback on an earlier version of these instructions. I would NOT have made any
improvements without their input.



NOTES:

- After Build-A-Pi (BAP) is installed, you can run it from the Applications Menu. This
menu **is** the Raspberry-Pi icon in the top left corner.

- You can change the default user’s (pi) password using raspi-config .

- You can change the default vnc password by left clicking the VNC icon. (It’s along the
top in the “panel”.)

Jesse.
I use the Sabrent too.
Its fine for all my radios (K3, KX3, FT897 etc.)
Works first time and doesn't need any drivers -- just make sure you select the right one from the 'pull down' in FLRIG!
