WRR - something

A web-based remote control for your HAM radio RIG, in python, html5 and javascript.

Goals:

1. display the rig freqency, mode, etc.
2. display everything
3. control everything less PTT
4. 2-way audio streams
5. control PTT

Note that part of 1. is that I own transverters and this code displays the input/output freq. of the transverter.

So further goals:

6. Control transverter off-set
7. Select a transverter

Screenshot

• Top: The transverter frequency: click the MHz part to select a different offset
• vfo: The current VFO, click to switch VFO
• split: split mode: clcik to switch the split mode on, text becomes green when in split mode
• HI SWR: Hi SWR indication, text becomes red when teh TRX replorts a high SWR
• centered: green when in FM and the frequencies match
• usb: current modulation, click to get a drop-down to select a mode
• Green dot: Squelsh is open, will turn red when transmitting, greq when the squelsh is closed in receive mode
• Bottom: the real frequency the rig is tuned to

Note:

Code is in alpha state. I've been able to display the freq. on the rig on the website, but nothing more has been tested.

Setup:

install:

• nginx
• uwsgi
• uwsgi-python3
• python3
• python3-flask
• python3-redis
• python3-serial
• redis-server

or whatever these packages are called on your favourite OS/Distro. Be sure to have something fairly recent. Debian stable won't do, testing will. Most notably you want a recent version of flask (0.12) and redis (3.2.6 or 'better'). Of course nobody forces you to user nginx and uwsgi, but this is what I use and works for me.

I just started woring in /var/www/html and /var/www/wrr, if you like other paths better, feel free to adjust the nginx and uwsgi configs as you see fit.

nginx

server {
	listen 80 default_server;
	listen [::]:80 default_server;

	root /var/www/html;

	index index.html;

	server_name _;

	location / {
		# First attempt to serve request as file, then
		# as directory, then fall back to displaying a 404.
		try_files $uri $uri/ =404;
	}

	location = /wrr { rewrite ^ /wrr/; }
	location /wrr {
		try_files $uri @wrr;
		# proxy_set_header Connection '';
		# proxy_http_version 1.1;
		# chunked_transfer_encoding off;
		# proxy_buffering off;
		# proxy_cache off;
	}
	location @wrr {
  		include uwsgi_params;
  		uwsgi_pass unix:/tmp/wrr.sock;
	}
}
