Go back to square one: set the RRC's to the default IP address and connect them directly using a single ethernet cable. Then
you can see if it is a network problem or not.

If it still doesn't work, you need to look into wiring, settings and power supplies as the problem.

Well, that missing important information. I assumed that you were outside of your network,
since you had a SIP error.

Indeed the ISP has no effect on what is going on within your
network. However, the router may still block packets to
"protect" your internal network. So still make the checks and
changes I suggested.

This type of problem is usually caused by router or even ISP issues. It could be a number of things,
so process of elimination will be the only way to solve it.

To start, make sure that SIP ALG is disabled on both sides. Then turn off the router's firewall to see
if that solves the problem. You may try changing the three UDP ports to see if that makes a
difference, but that rarely helps (unless you have an old RRC running port 5060, which must be

If that doesn't help, take the control RRC to another location. If it works there, you know that the
problem is on the radio side. Otherwise you can focus on the control side.

I can send you my networking checklist, but it appears that you got things working and probably
don't need it.

Do the radios work in Twin mode ok? is the problem only that you can't get CAT working, or more?

The cable between the radio RRC COM2 and the rig  is a straight through normal serial cable and
the one on the control side a normal null-modem serial cable that can be bought anywhere.

I also noted in the manual on page 149 that they recommend to use mode-6 instead of mode-7 for
COM1. I don't think that will make a difference, but you can try it.

Hi Marcello,

NO, that is wrong! You did not understand the instructions correctly, no cable should be changed on the radio side,
otherwise you Yaesu Twin setup will no longer function.

All you need to do is to make one change on the RRC settings, which you can do remotely, assuming you forwarded
the RRC's web port. Here are the instructions again:

- Change the radio RRC's serial settings for COM1 to mode-7. Note that the baud rate does not have to be identical with
COM2 to fit a lower bandwidth or software requirement.

- Change the control RRC's serial settings for COM1 to mode-7. Make the baud rate the same as you made COM1 on the
radio RRC

- If using a "real" serial cable or USB to serial converter cable:
     - connect between the control RRC's COM1 and the PC. If using a USB to serial converter, make sure it is a FTDI
       version and not Prolific
     - The  serial setting for COM1 "Use USB Com Port as COM1" must be set to NO

- If using a USB cable:
     - make sure that first Microbit Setup Manager is installed first on the control PC to get the drivers.
     - Then change the serial settings for COM1 to change "Use USB Com Port as COM1" to YES
     - connect the USB cable between the RRC and computer and wait for the drivers to finish installing
     - go to the Windows Device Manager and look at which virtual serial port was assigned to COM1 and use that for
        your software, taking the correct baud rate into account.

Hi Marcello,

The instructions for you are also above:

"Then go to both RRC's serial settings and set COM1 to mode-7 (copies CAT data to COM1). Then use
COM1 for CAT on either side instead."

Did you try that?

Hi Paul,

This normal behavior when the RRC does not get 12v and uses only USB power. Did you check the power supply?

Otherwise, Mike will have to help you out, even though he is on vacation until August.

Never do a port forward and DMZ for the same ports at the same time. It usually causes problems.

I tried to look at your RRC using the address above, but it no longer works. I suspect that is because
of the above.

Mitch DJ0QN / K7DX


What doesn't make any sense is that you can reach the radio RRC's web page, so obviously the DDNS address is correct.
Or how are you doing that? The control RRC's SIP contact should therefore reach the radio RRC in that stage.

Did you try rebooting the radio RRC?

Mitch DJ0QN / K7DX

Any rotator controller that has a serial port can be remoted using the RRC's COM1 port as a serial server.

As for the type of rotator control software that is best for the blind, I suggest you ask Handihams to get their suggestion.

Good luck!

Mitch DJ0QN / K7DX

Leave off the :8091, that is not part of it.

Mitch DJ0QN / K7DX

Remove the http:// from the SIP contact, only use the DynamicDNS address.

Mitch DJ0QN / K7DX

.....and make sure that your port forwards are correct in your router.

If you need my networking checklist that walks you through the process, drop me a short
mail at dj0qn (at)

You and everyone else is welcome to ask anything at any time. I was just pointing out that the forum is a great resource
and that one should first try the search function first to save time. I was just using this as an example, because it is a
common question.

Please don't take it personally and continue to ask anything that you want.
