Icom Remote Operation and Router Settings

Hello friends! It has been a while since I wrote about Icoms RS-BA1 software (Icom remote software). I am still using the old version, but this time its from outside my home. See my previous posts, Icom 7610 Clock, Timers and Network- How To and Icom 7610 RS-BA1 Installation and Settings if you don't have it working yet on your LAN. This post will deal mainly with configuring your router to allow outside connections to your Icom transceiver. Whether it's an Icom 7610, 7700,7851, etc., these router settings will work.


There are a lot of different routers out there so I'll try to explain this in general terms, but specific enough to get you going.

I have a cable modem with router. I recommend cable over other broadband services. It can serve your needs and usually be upgraded by just a phone call to your cable company. No matter where you get your service from, they will either rent a modem to you or sell you one.

Router Settings and Icom Remote Utility

To use the Icom remote software from outside your residence we need to open up your Icom radio to the outside world. When you get a modem (router) from your service provider they will be secure and will not allow outside connections to you LAN (local area network). This protects your computers from outside attacks.

My modem is a Hitron, very popular and easy to configure. I get into the router software by typing it's IP address ( in my browser window. Once I login I go to the Basic Settings and Port Forwarding. No matter the brand of modem you have look for Port Forwarding and configure it similar to mine below.

I added three rules as seen above for ports 50001, 50002 and 50003.

The HTTP and Spider settings you won't need, so you can ignore those entries.

You will want to open ports 50001 thru 50003 to the IP of your radio. Save it and that's it.

Icom Remote Utility

Open your Icom remote utility and setup the WAN connection. The address you use will be your routers WAN IP or public IP. To find it, ask your service provider or use "What's My IP" while you are browsing the internet from your homes network. We want the IPv4 address. See mine below.

router ip

I have a DNS service (using pi.k0pir.us), but I could just use my IP If your IP from your service provider is dynamic as mine, the IP may change every now and then. Sometimes mine doesn't change for a year or more. Use your IP to uncomplicate things. You can add a DNS service later when things are working.

As I have mentioned before, get your radio working on the local network (LAN). If it works there and does not from the public IP, you have something misconfigured in the router. Troubleshoot from there or ask your service provider for assistance.

The problem is not with the Icom remote software RS-BA1 if it works from the LAN and you have configured the outside connection correctly as I have above.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

Hi Rich. It seems that this LAN feature is only addressed by IC-7610 and not for IC-7300 (my current rig). Am I right?

I use RS-BA1 between server and radio in garage and client located at my upstairs office. My problem appears to be router as radio disconnects frequently. I’ll move the router to see if it improves. As I listen real time there will be audio dropout and the spectrum display freezes, so certainly losing comm between the two. Any ideas? I might buy a wi-fi extender. Kindly, Daral
