David,

Did you change the SIP port to something other than 5060? That is critical, since 5060
is blocked in many routers and most hotels for VoIP use.

Hi Roy,

Glad to hear that you have the 2820 running ok.

I am not sure why you heard that the IC-7100 will not function on 40 & 80 meters.
The specs have it as a full HF rig down through 160 meters. See the Icom web site
for full specs:

Since I haven't seen an answer from Microbit yet, I will send you one from my side:
the answer is NO.

Whether or not they are planning to make an Icom "Twin" or not is up to them, but I
highly doubt that the market is large enough to justify the development expense. There
are already excellent solutions available, including support for the new IC-7100.

Hi Petr,

You have an interesting problem, but it still doesn't make any sense. Why would the RRC all of
a sudden, without any change whatsoever, begin to generate packets "backwards"? I can not
believe that it is a problem with the RRC and for sure must be a router issue. I have seen routers
do strange things like you are showing on your screen shot before, I just can't remember right
now how we solved it.

My suggestion is to borrow another type of router from someone and see if the problem
persists. Then at least you can confirm or eliminate the router or RRC as the source of the problem.
I have had good luck on VDSL with the Fritz!Box 7390, although I do find it too "dumbed down" for
my taste.

General discussion forum / Re: Remote Rig and Yaesu FT-847

« on: 2013-02-11, 14:02:10 »

Probably you haven't received any answer is because this is not necessarily the type of radio
that one would use with RemoteRig. The true "power" of RemoteRig is using a remote control
head to operate a rig with the true feeling of being in front of the radio. The FT-847 would require
full software control, for example using HRD.

The advantage the RemoteRig would give in this situation would be CW paddle support, excellent
SIP based audio and latency, as well as virtual serial ports. If these items are not important to you
and you want to stick with the FT-847, then you could just as well use a remote PC and Skype, if
that is all you need. If the CW paddle support is not important, but the others are, then use the
RRC PC Client and save on the control RRC.

You can use the tuner built into the rig for most purposes. If you need another solution, e.g. with
an amplifier or for twin lead, then that is a different subject and we can point you to some earlier
threads on that subject.

Hi Chris,

For me the killer is the new virtual serial port that you can use with the Webswitch to control a rotor.

Hi Petr,

Sorry to hear about your problem. To be honest, it doesn't make sense to me. There  should
be no difference whether you use ADSL or VDSL. I also switched to VDSL 50/10 three years ago
with no difference.

You only refer to a modem in your explanation. Do you have a separate router to the modem, or
are you referring to a router/modem combination? If you had a separate modem and router, then
switching to VDSL should make no difference. If you changed a combination router/modem, such
as to the Fritz!Box 7390, then of course you need to reenter all of your port forwards again.

Maybe you can clarify this point.

Hardware, Cabling, Installations / Re: RF-Protection filter for DSL-Modems

« on: 2013-02-06, 11:32:53 »

Also from my side thanks, Mike, that looks correct.

One would need two of these cables for connecting to an analog line, one on each side of filter.

For an ISDN connection, it is a bit more complex, because you must use the Y-cable that AVM
supplies with the Fritz!Box. In that case, you would need one of these cables between the filter and
splitter. To connect the Y-cable to the filter, you need some sort of adapter that accepts the RJ45
from the Fritz cable on one side and an RJ12 on the other side.

I could not find such an adapter on the Conrad web site, however I remembered that the standard
RJ45 receptacles usually accept an RJ12 connector as well. Therefore, I believe that a standard RJ45
coupler will do the trick. Just plug the Fritz RJ45 plug on one side and use any standard RJ12 analog
telephone cable on the other side (or of course a 2nd cable as above would work as well). In case you
don't know what I mean, here is an example:
http://www.conrad.de/ce/de/product/922723/WESTERN-ADAPTER-64-SW
No guarantee that this will work, but I believe it will. I can try it some day with my ISDN line and Fritz!Box
when I can borrow a filter.

Mike,

Since the Fritz!Box has a >50% market penetration in Germany, we should quickly have a simple
example of what one must do to hook this up. A link to the right cable or adapter at Conrad or
Reichelt would probably be best. If anyone can take a look, that would be great.

General discussion forum / Re: RRC with 3G private IP - any solution?

« on: 2013-02-05, 15:44:57 »

Hi Mike,

The problem is not the ports, it is the IP number. You receive an internal IP number, because the
3G/4G providers here do not give you a public IP number. This creates a "double NAT" and makes
it impossible to host a system.

Robert,

I know a couple of people using VPN's to solve that problem. At least in Germany, that is the only way
to host a remote station on 3G or LTE.

One example of what they are using is http://www.portunity.de/

General discussion forum / Re: How Much ACTUAL Bandwidth Needed to support reliable operation

« on: 2013-02-02, 22:00:55 »

Bill,

That bandwidth is no problem. Although you will get different opinions from everyone, in general you need to add the following together to get the bandwidth required:

- COM0 serial port bps
- COM1 and/or COM2 bps if used (i.e. for CAT or rotor control)
- which CODEC you are using, refer to appendix A in the Manual. I use CODEC 0 for almost all of my stations, which has proven to be more than adequate for SSB and CW.
- If you are running single or dual-channel audio (this doubles the codec rate requirement)
- There is probably some overhead in the 20-50 bps range that I would just add-in as well

Remember also that this is doubled, up and down! Most DSL lines are asynchronous and have a lot less bandwidth going up than down, but the internet provider usually only advertises the down speed. You need therefore to take into account that the bandwidth used by RemoteRig  is the same in both directions.

A corollary is the serial ports sent over the RRC, including CAT. It is not always necessary to run them at 57,600 bps! When possible, reduce them down to e.g. 4800 bps and reduce your bandwidth that way.

I also need to point out that I believe that the latency is far more important than the bandwidth, especially once you are over about 250k bps. Often 3G lines have severe latency problems making them unusable, and satellite is not advisable at all.
