I resolve a number of RemoteRig problems for users every week, but recently I had two unusual problems in Germany and Spain
that turned out to be a new issue that will likely come-up more and more often. I therefore want to warn the user community
about how to recognize this problem and how to possibly solve it.

The effect of the problem is that a previously perfectly working setup just stops working for no apparent reason. In general,
a working system that stops working is not due to a RRC defect, but due to a change somewhere in the environment (e.g.
router, loose cable, etc.)

This new problem is caused by the migration of internet providers from IPv4 to IPv6. The provider changes the IPv4 connection
to the internet to a new type of "encapsulated" link that shares a single external IP number with its users. This means that the
users no longer have an external IP number on the internet that can be used to reach devices within the users' networks using
port forwards (called "double NAT"). The RRC is therefore all of a sudden no longer reachable and the system goes down.

How to recognize the problem: you need to go into your router and see what IP number the router has received from the provider.
This is under a menu called "status", "WAN" or similar. Then go into your radio RRC's status page (or use a browser to go to and see if the external IP numbers match or not. If they do not match, then your provider made this
change. If they do match, your problem is elsewhere in your hardware or network.

How to fix the problem: there is no real fix as such. You need to contact your provider and see if they can give you a true external IP
number as you used to have. If they can not do this or are unwilling to do this, then you will need to change your internet provider.
As an alternative, you can setup a VPN, but this is beyond the scope of this posting.

General discussion / PC Client Running Under VM Under Mac
« on: 2014-07-24, 16:28:58 »
I received an e-mail from an OM that I have been trying to help get his remote station working.
I just found out that he is trying to run the PC Client in a VM using VMWare on the Mac. He says
that everything appears to work, but he can't hear any audio.

Has anyone got this configuration working ok? Is is a configuration issue, or is this a technical
problem that can not be solved?

Allmänt diskussionsforum / Visit to Stockholm
« on: 2014-03-25, 20:54:05 »
Sorry for the English posting......

I will again be in Stockholm next week and was wondering if there will be any club meetings that
I can attend. I arrive on Sunday evening and leave on Friday.

E-mail directly to dj0qn (at)

Thanks & 73,

Note that the control panels for the Icom IC-7100 are now available separately. This means that you
can have multiple users for RemoteRig radio sites using these hardware control panels.

Difona now has them in stock at 299€ and I assume that other dealers can get these from Icom as well.

I thought it had become very quiet lately.....the problem is that notifications are no longer being sent when
a new posting is made. I verified that I am still subscribed to the notifications under the categories I am
interested in.

I guess this has been a problem for a couple of weeks now, so hope I haven't missed anything important  >:(

This is actually quite a clever approach, even if a bit quirky:

I thought I would share this in case someone is interested.

Configuration, RRC 1258 / Bugs in Network Settings
« on: 2013-05-22, 11:34:54 »
I have some new RRC's that I need to configure, but have run into some bugs that
I have not experienced before. I am not sure if these are FW related, or if I really
never had this situation before in all the RRC's I have installed.

This is for a control RRC using FW 2.72 and Setup Manager 1.20.

1) I imported a .bin file that had a fixed IP number. Instead of using the Default
profile, I changed to another profile before importing. Using Setup Manager, I changed
this to DHCP. However, it never changes that profile, only Default. I found that first
importing to the Default profile and then changing to DHCP works. However, the
one I already imported in another profile can not be changed and this profile is now "lost".

2) I tried a hardware reset to start over again, but all this does is to clean the Default profile.
All the others are untouched by the hardware rest. I tried holding the button down many times
for several periods, even more than a minute. I tried disconnecting the USB cable first and even
the power before doing the reset. It just does not work.

3) What is also strange is that the reset changes the default IP to fixed for all profiles. When I
use Setup Manager to change the Default profile to DHCP, it leaves the others as fixed. However,
Setup Manager shows these profiles as DHCP on the "Setup" tab. Moving to the "Net Info" tab,
it shows the IP address as fixed.

Bottom line is that this new RRC is essentially "bricked". I will try later to set another PC to
the RRC's default IP subnet and see if I can fix it that way, but this really needs to be fixed.

General discussion forum / Dayton
« on: 2013-04-22, 13:06:00 »
As a heads-up for everyone: Mike will not be coming to Dayton this year. You can of course
receive assistance at the Ham Radio Outlet booth. If anyone has specific technical questions,
I can usually help you out. I will be working about 50% of the time at the DARC booth, which
is located on the ARRL Expo. Otherwise, contact me via my U.S. cell number 424-288-9171
starting after April 27th until May 19th.

We will first be in Phoenix, AZ, then the following week in Naples, FL. On May 8th, we start
the trek up the coast to Dayton through Jacksonville, FL, Charleston, SC and Charlotte, NC.
I plan to have my APRS running as K7DX-9. Give me a shout if I am in your neighborhood!

73 and see many of you in Dayton,
Mitch DJ0QN / K7DX

I have helping a few people out the past couple of years setting their RRC's and network up. I
already am pretty well equipped to support the most common rigs in use, but one that often
comes up is the IC-706. Until now, I haven't been able to help people test their 706 installations.

Therefore I bought an IC-706 control head over Ebay, so now I need a control RRC to install it
with. If anyone has a spare control RRC, please drop me a mail at dj0qn (at) and let me
know what you want for it. An older single audio channel version would be fine for this purpose.

General discussion forum / Winkeyer Function
« on: 2012-12-11, 18:43:02 »
I noticed that there is now a "mode-8, winkeyer" mode available in the serial settings.
I find no reference to this in the manual. Could you please enlighten us on what this
can be used for?

Since I extensively use Winkeyer for CW, this may be of interest.

General discussion forum / New Bug in Yaesu Twin
« on: 2011-09-22, 14:32:40 »
Yet something else strange came-up.....I can no longer access my radio RRC, it does not accept my user
name and password. Since I use the same name/password for both RRC's in that station and have made
changes before, this must be a bug in 2.41 on the Yaesu Twin. There is no other way to explain it. There is no
one else that has access and it is "hidden" behind the router. I also tried telnet with the same problem. And of
course this is the only RRC I use that I forgot to backup the config file, so it will be some work when I can get
a chance to make a hardware reset. Oh well.

To summarize the open issues I have with Yaesu Twin with 2.41 (FT-2000 --> FT-2000):

- User name/password stopped working
- Low audio output, no difference how JMP4 is set (using amplified PC speakers)
- Changing antennas in split uses only the last one set by the radio side on the B VFO
- Some controls are inconsistent, such as power output. Haven't spent time trying all controls

Sorry to be a pain, guys  ;)

General discussion forum / TS-480 + RRC without Head?
« on: 2011-08-31, 16:28:34 »
I just exchanged a few mails with a local OM who has ordered a combination of equipment
which I am not so sure makes any sense.

A group of three people ordered one TS-480, one full set of RRC's and two control RRC's. The
plan is for one person to use the TS-480 + control RRC remotely (as usual), but the other two
users are planning to use the TS-480 over their RRC's without buying extra heads. They plan to
use only HRD to control the TS-480.

My logic says that they should have ordered the PC Client when they don't want to buy a head,
but the order is already completed. I therefore tested one of my RRC's to see if I could get this
to work like they want by removing the cable from the head. As I suspected, I could not get HRD
to connect to the remote RRC in any way, only when I first plugged back in the head and turned
the TS-480 on, did HRD connect up as usual through the CAT port on the the RRC COM2.

So the question is: has anyone found a trick or work-around for this type of operation? Or have
these two guys really made a mistake?

General discussion / PC Client with Yaesu Twin
« on: 2011-08-22, 21:54:43 »
After using my PC Client for several months with my TS-480 setup, I tried to use it with my
new Yaesu Twin setup with 2x FT-2000.

The PC Client connects as it should and appears ok, but I can not get the CAT to connect
at all. I have tried with both HRD and TRX-Manager.

I turned my webcam on the FT-2000 in the remote station and can see that the FT-2000 does
not turn on when the PC Client connects to it, as the TS-480 does. I can't turn the FT-2000 on
via software, since the CAT doesn't connect.

Since PC Client support will be critical to a new installation of Yaesu Twin I am doing next month, I
need to figure out what the problem is pretty soon.

Thanks & 73,
Mitch DJ0QN / K7DX

My second YaesuTwin issue I would like to report is the low audio level
on the main receiver. It is really too low for me to hear weak signals, even
when using headphones and turning the AF Gain up all the way.

The second receiver is OTOH much louder and is as loud as I would expect.

I tried moving JMP-4 back and forth a couple of times, but can tell no
difference in the audio output. I left the Codec Out Gain at 255.

Any idea how I can raise the audio output level?

Mitch DJ0QN / K7DX

Since there is no separate YaesuTwin section, I am adding a couple of issues here.

I tried working split for the first time since installing my YaesuTwin with two FT-2000s.
I receive no power output, although it works just fine when not in split. Switching between
the A and B VFOs makes no difference, always full power out in simplex and no power output
in split. This occurs for both SSB and CW and across the bands. I have used the A-->B button
and made sure that everything is identical.

Any idea what is happening here?
