Abstract:   "How to remote control your ICOM radios the cool way"
                  What do I mean the cool way.    Just point your RS-BA1 Icom software at your own Domain name,
                  and not have to worry that your ISP has changed your DHCP IP address while you weren't looking!

Prologue: I have seen several presentations on how to remote control your ICOM radio from the Internet, youtube etc.
   This is just another way using a radio domain name, and I depict the router configs which seems to be the hard part
                 of this operation for most ham users.

How to get started:

o - Get a radio domain name here: https://www.encirca.com/    just use your call: example n2fan.radio   $30 bucks a year.

o - SIgn up for a DNS service, I use zoneedit.com. (it's free)   http://zonnedit.com

o - Set up your encirca radio domain DNS

o - Get a Raspberry Pi board, any vintage, although a Raspberry PI4 is a good way to go, or any other Linux based CPU/board.
     (More later)

SETUP:

o - Set up your encirca radio domain DNS setting like this:

o - Set up your Zoneedit DNS like this:

o - Raspberry PI.
     ok, so why do you need a Raspberry Pi?
     The ddclient program you install will query your routers WAN address every 600 seconds,
     and if that IP address changes it will feed that change info back to the zoneedit DNS server,
     So all you have to do it point your ICOM RS-BA1 software to your radio Domain..   (ex   n2fan.radio)
     More on Router setup later.

1) built your raspberry PI board, the default Raspbian OS (operating System is fine)
     2) Install ddclient : (as root or use sudo) example sudo apt update, sudo apt upgrade sudo apt install ddclient:
          apt update
          apt upgrade
          apt install ddclient
          You can install ddclient via the GUI or here's an example of the config file:

           /etc/ddclient.conf

use=web, web=http://dynamic.zoneedit.com/checkip.html
login=yourzonnedituserid
password='yourzonneditpassword'
syslog=yes
mail=root
protocol=zoneedit1
server=dynamic.zoneedit.com
yourradiodomainname   (n2fan.radio)
www.yourradiodomianname (www.n2fan.radio)


O - This will do it for stage one.
        To follow from the main web page is:

   o - ic-9700 network and CI-V config setup
   o - ic-7610 network and CI-V config setup
   o - ic-9700 Router rule and port forwarding configs
   o - ic-7610 Router rule and port forwarding configs
