I now have a portable RRC + TS-480 head in a small case that I have been using during
some vacation and portable operation. I have noticed two issues and have a suggestion
to fix them:

1) If you book your PC and RRC separately into a local network, either through Ethernet or
   wireless connections (RRC using a bridge), then sometimes the networks do not allow
   peer-to-peer communications between these two network clients for security reasons.
   This means that you not only can not access the web-based menus to change RRC
   settings, but are unable to change between your profiles for target remote stations.

2) When you are in a location with a fixed IP number, you can easily change this by using
   the Setup Manager via USB cable. Unfortunately, this also changes the RRC back to the
   "default" profile, and at that point it may not be possible to change to the correct profile
   if you have network issues like in 1) above. I noticed that in some cases, since changing
   to a fixed IP number does not allow you to set a DNS server, that this was the cause of not
   being able to reach the RRC.

Suggested fix: just add the ability to make profile changes to the Setup Manager. At the
same time, maybe you can add the ability to manually enter a DNS server address when entering
a fixed IP number.

Not critical stuff, but sure would make life easier for us traveling with RRC's and using multiple remote stations.

General discussion forum / New Hum Problem with 2.41
« on: 2011-07-13, 10:28:21 »
Just a heads-up: there is apparently a problem with firmware 2.41 that causes hum when the USB CAT is used.
This is the same or similar to the problem that occurred in firmware 2.35 and was fixed right away. See for that thread.

It is the same user that is having the problem. He is away today, but I will try to get more tests and details
from him before I leave on vacation this weekend. It appears so far to be identical to what he experienced
in 2.35, so he has downgraded to 2.39 for now until this is clarified or resolved.

General discussion forum / YaesuTwin Inconsistent Controls
« on: 2011-07-07, 16:27:15 »
I finally got my YaesuTwin into full-time operation, after having one of my FT-2000's
upgraded with the NS filter over the last month.

I have experienced inconsistencies between what is indicated on the local FT-2000
and the remote FT-2000. I am running TRX-Manager on the remote side and can view
and control some settings that way using VNC.

Some controls appear to work just fine, e.g. shift, width and basically everything on
the right side of the rig. However, some controls do not work, even if they appear
correctly in TRX-Manager.

One example of this is the power control. I can change the local FT-2000's power
level and TRX-Manager follows it with the slider. However, the actual power on the
radio side does not change, you can see this in the display on the TRX-Manager
monitor screen, as well as through my remoted LP-100 wattmeter. If I then go and
change the slider on the TRX-Manager control screen, the power really changes.

Another example is the mic gain control. This appears to have no effect at all. Since I can
not monitor this in TRX-Manager, I can't verify what is happening. I believe it is not working,
because my output power on SSB is very low, and the amplifier does not appear to even be
in line. Since the amp works in CW, it can not be a keying problem with the PTT. I listened to
my output on a local rig, and my audio appears fine, just the signal is weak due to low power

I can try to figure out which controls work and which don't, but maybe by looking at these two,
mic gain and power, you can see if there is a general issue.

Thanks & 73,

General discussion forum / CW Key Plug
« on: 2011-06-22, 19:12:43 »
I have a strange problem with the CW paddle connection:

I have three remote installations using RemoteRig and TS-480's that I currently manage.

In one of them, RemoteRig works just fine with a CW paddle cable plugged fully in the RRC's and TS-480's jacks.

In two of them, it does not. If you plug the cable about two-thirds of the way into the jack on the RRC,
then it works just fine. If you move it out a bit or push it all the way in, it doesn't work.

All three installations are identical, both in hardware and in RRC settings.

Anyone have a clue why this would be the case? It is not a "killer" problem, but it would be nice to solve this mystery.

General discussion forum / FSK
« on: 2011-06-01, 14:37:09 »
Has anyone been able to use their RemoteRig RRC to do "real" FSK, not AFSK? I am
not a digital mode person, so I am not sure if this is possible.

I am getting involved in an interesting project that may use K3's controlled using
RRC's, but apparently FSK is a requirement.

General discussion forum / YaesuTwin Install Problem
« on: 2011-05-31, 19:05:27 »
I finally got my YaesuTwin installed at the remote location, but the connect does not work.

When I hit the connect button on the status page (the power switch has no effect), then
the remote FT-2000 turns on for about 2 seconds, then switches off again. I have a camera
mounted there and can control how the remote FT-2000 responds.

I have double and triple checked my settings, but everything appears ok. I have installed several
RRC's by now and pretty much know most things. I also moved this new (Yaesu) RRC into the
DMZ for a short test, with the same result. So it is not a network port issue.

I am using firmware 2.39 on both ends. I have changed and forwarded all ports to be different
than the other RRC that is installed at the station (in the DMZ). I also killed my other RRC for
a minute to make sure there was no "interference" issue I overlooked.

Since the manual does not cover operation of the YaesuTwin (only installation), I am assuming
there is nothing significantly different from the RRC-1258.

Maybe someone has a clue what is wrong.

General discussion forum / TS-480 Keyer
« on: 2011-04-07, 17:14:49 »
I was reading the eHam reviews of the RemoteRig, and came across the one written by
K7CF on January 2, 2011. In his review, he writes:

"I tried CW and you can either use the internal keyer in the ts480sat (DEFAULT) or you can
use the Key input of the built in keyer of the Control black box. I use the internal keyer in the

This is at

I use the TS-480 as well, but have never seen a way to switch between the two keying methods,
except for accessing the TS-480 internal keyer with software and the RRC keyer with a paddle. Am
I missing something here? K7CF did not respond to my mails to two different addresses.

I have a user that has a problem that I am unable to duplicate with my set-up.

His installation has been working just fine until now. He upgraded to be able to use
the new USB to COM2 feature of firmware 2.35.

However, he starts gets a loud hum come after about two minutes of turning the
TS-480 on, and the head turns off at that point. Here are some details:

- TS-480 head with RRC firmware 2.35 (upgraded shortly before problem started)
- New USB as serial feature enabled ("Use USB Com Port as COM2")
- Appears that the RRC maintains connection to station RRC after head turns off
- Cables (ethernet, RRC--> head) checked and ok
- Swapped power supply with no change
- Removing USB cable makes hum continuous
- Changing "Use USB Com Port as COM2" back to NO, solves the problem,
   but of course doesn't allow the CAT through USB

I can send an MP3 if someone wants to listen to the problem.

I would say that this is a bug in 2.35, but as I said, I can't duplicate it locally.

General discussion forum / Firmware 2.35?
« on: 2011-03-21, 13:31:32 »
The RRC-PC Client 1.14 has been out a couple of weeks, and in the description ist says:

" JitterSize and JitterDelay are now sent in SIP/SDP header. ( need v2.35 of RRC)"

When will 2.35 become available?

General discussion forum / Yaesu Twin Question
« on: 2011-03-20, 17:40:46 »

I am interested in the Yaesu Twin for my FT-2000. I have an offer for another
FT-2000 that I am considering for the control.

My question is: does the CAT have to go only to COM2 as in the instructions,
or can I also put it to COM1 and loop it through COM2 as on the other RRC's?
I would need this loop-through capability to prevent breaking my present set-up.

Dumb (bonus) question: why is the Yaesu Twin so expensive? The cables can't make the
difference. Appears to be the same hardware to the other RRC, probably with a
different firmware (but no updates are showing on the download page yet). I assume
this is a marketing driven price, but it seems very high. I don't expect an answer on
this question, just wanted to get it off my chest!

Configuration of Routers, Firewalls, etc / SIP ALG
« on: 2011-03-04, 11:56:10 »

I see a lot of warnings to have SIP ALG turned off in the router. I have
never read what the effect is when it is turned on. Could you please tell
me what problem it causes?

I am asking, because I am trying to debug an installation where I do not
have direct router access. I don't want to request a change unless it is
necessary. The problem is audio breaking-up at irregular intervals, even
though the line is very fast. Maybe SIP ALG is the problem.

Thanks & 73,

The RemoteRig guys brought out a cool feature in 2.28 that (as far as I understand)
should allow a the rig's CAT to "loop through" the RRC and out again, as well as to
allow the remote RRC or PC Client to use this CAT at the same time.

We tried this yesterday with a TS-480 and SPE Expert, but couldn't get it to work.
Although I tried various settings, I probably screwed something-up. Here is the scenario:

- Connected TS-480 CAT port to COM1 on RRC
- Connected SPE to COM2 on RRC
- Set radio RRC COM1 to (new) mode 6: CAT to COM2
- Set radio RRC COM2 to mode 4: Kenwood
- Baud rate is set to 9600, since this is maximum the Expert can support for Kenwood
  (both COM ports in RRC, as well as in TS-480)

Here is the result:
- The TS-480 and Expert work fine when connected directly together
- The loop through does not work
- When trying with a Y-cable from the TS-480 that goes to the SPE and RRC, the
  CAT control dies when plugged into the RRC, but works when unplugged
- Do the COM terminators have any relevance?
- I also can't pick the CAT up over the remote side when using this scenario. I tried
  with the PC Client, since it is easier to use in this case

I am probably doing something obvious wrong, so if someone has been able to get
this to work, please advise.

General discussion forum / Feature Request: Profiles
« on: 2010-11-24, 16:58:32 »
Mike and the guys have done a great job enhancing the RemoteRig platform.

There is one feature that I would really like to see: being able to import the
settings file that the box now produces when you export the settings. In
addition, it would be great to be able to manage multiple profiles for settings,
in order to be able to quickly switch between different server RRC's.

Our group is in the process of deploying at least one radio side with multiple
users. This would make it possible to easily add these users. Since some of
us will use more than one installation, adding profiles would improve this even
further. If we could at least get an import function soon, it would be a great help.

Although I find 2.26 to be stable and a good improvement, I noticed that
the DynDNS update no longer works, and returns an error message. I
use the RemoteRig as a backup to my router's DynDNS with a different
address, so it is not mission critical, which is why I just now noticed the

In checking my log on, it indicates my last update took place
the evening of Oct. 28th, which is when I installed 2.26.

General discussion forum / Network Noise Problems
« on: 2010-09-15, 18:29:53 »
I have been trying to resolve a problem for several weeks now, but am not really getting anywhere. Maybe someone else has had a similar problem and knows the cause.

Most of the time, I have a type of crackling "popcorn" type of noise on the control side. Often it even gets worse, with "holes" in the audio, as if the internet connection is bad. Although I believed till now it is caused by the router, I am not sure. The network is fast and should not be the cause. The RRC's show no SIP error. I have exchanged many mails with AVM's support, but they can not find a problem from their side, and the router is designed for high-speed video and audio streaming (I have IPTV installed). Removing other devices from my network does not have any effect.

Here are some details:
rig: TS-480
DSL control side: VDSL mit 50Mb down and 10mB up (T-Home)
DSL radio side: ADSL2+ with 16Mb down and 1mB up (Alice)
Router control side: AVM Fritz!Box 7390
Router radio side: DrayTek Vigor 2910
both LANs use only gigabit switches
RRC: SIP port 5090 (changed due to VoIP routers), have tried various settings for jitter buffer, delay and packet size without noticing a difference

If no one else has a tip, I will do some other types of testing, i.e. taking the control RRC and TS-480 head to another location, or maybe try a different router. This is really a head scratcher.
