I now have My UI-VIEW parameters set to 20KM to stop my screen getting swamped

31 10 23. Due to on-going issues with Weather Underground, I am now using the Ecowitt API
Ecowitt wn1900 Weather Station - Ecowitt website
Cumulus MX software (wxnow.txt) - APRSIS32 - Sound Modem by UZ7HO

The Ecowitt wn1900 Weather Station transmits the weather data to the Ecowitt website.
The Cumulus MX software picks up the data from the Ecowitt website via an API and the internet,
The Cumulus MX software produces a text file called wxnow.txt
APRSIS32 picks up the text file and converts it to APRS WX data which is then transmitted onto aprs.fi,
and APRSIS32 transmits via the Sound Modem and YAESU FT227 to 144.800 MHz.

wx_player (by f6dqm) also picks up the 'wxnow.txt' file and converts it to speech,
wysiwyh (what you save is what you hear by f6dqm) and saves the speech to a '.WAV' file.
This wav file is picked up by echolink and echo news mp3 plus and broadcast over the air.
currently set to broadcast locally via RF every 15 minutes.

Three messages are sent every 15 minutes.

IDENTIFICATION IN MORSE, WEATHER IN VOICE, IDENTIFICATION IN VOICE.

This system involves 4 computers.

CURRENT SET UP as of 08 05 2023

Using a Windows 10 64 bit laptop

There are various ways to connect your radio, I won't discuss this here

Files needed (For Windows 10 64 bit)

install python-3.8.0-amd64 HERE
install js8call HERE
install js8call utilities HERE

js8call utilities settings

Because I am a fixed station I turn off GPS and enter my grid location manually

manual position

The two options below show 1 minute and 10 minute tx intervals

IMPORTANT
when you click save, make sure you see the text below in the dos utils window

APRS Message screen - GPS Screen

This is a step by step guide to installing software for js8call and js8utilities on a rpi
as well as a host of other ham radio stuff by KM4ACK
found here https://github.com/km4ack/pi-build

video here https://www.youtube.com/watch?v=GkGcu6WaWsc

PLEASE REMEMBER EVERYTHING IS CASE SENSITIVE

https://www.raspberrypi.com/software/

the raspberry pi imager can download and install the correct version
it can also pre set up your wifi and ssh so you can run it headless.

with this done boot the pi and look in your router for the local ip address

------------------------------------------------------------------------------
log in to pi with putty

sudo su -
apt-get update
apt-get upgrade
answer Y when prompted
sudo reboot

sudo raspi-config

3 interface options
i2 vnc
yes
that enables vnc useage

sudo reboot

log in with vnc viewer

install updates if needed

in a terminal paste this in one go


git clone https://github.com/km4ack/pi-build.git \
  $HOME/pi-build && bash $HOME/pi-build/build-a-pi

install updates if prompted
please be patient
this takes 4 hours

note, after about 2 hours you may be prompted to click ok.
everything else is automatic

--------------------------------------------------------------------

PROBLEMS WITH GPS

Try the following, which is strung together from the previous comments:
(bold text are commands for the terminal)

In Terminal...
(1) pkill -9 conky
(2) conky
(3) sudo apt install ruby
(4) sudo gem install maidenhead
(5) sudo gem install gpsd_client
(6) reboot
