Ok we all know that D-star can be connected true the internet to a DCS, REF, Xref reflector.
I’ve been reading some articles and found out that the baudrate for the voice data is only 950bytes. This has to work on 3G i would say.
This has never been tested by anyone in the Netherlands.

In the Netherlands there is a 3G network that can run on 7,2Mb down and 1Mbps up. The lowest bitrate is 1Mbps some are even faster up tot 14,4Mbps.
Resent i orderd a DVAP Dongle to play arround with.

A friend of mine PD1RB had the splendid idea to hook up his Iphone with his laptop when he is mobile. That on a 3G network.
If then he runs the Dvap Software and connects to a Reflector is should work and you can communicate to repeaters that are on the same Reflector.

Yesterday it was time to test this methode. Will it work. What will happen when you drive. How stable is the connection.

Here the results.

I hooked up my Iphone 3G > laptop > Dvap > IC92D
I connected the software to the DCS007B reflector this one is also connected to the Repeater PI1UTR in IJsselstein.

Results of the test.

Audio is prefect. Only a i did hear a few glides when you change from GSM repeater to GSM repeater.

The buggy part is only the Software and the USB driver of the DVAP dongle. This is crashing from time to time.

The 3G network from t-mobile is stable and works good.
The test is 100% succeeded

There is not much on the market to fix en stablize a porto in a mobile.
So people has to use there brains to get an idea how to fix it.

At first i had the idea to buy a Desk chager and fix this near my gear lever. But the Desk Loader was to big hmmmm.
I had to come up with another plane.

GSM holder as almost out of order. Mobile phone are most connect true Bluetooth so why need a car holder.
My GSM holder is a standard thing in the car. I never used it. Hmm maybe this is a good place to but my Desk loader.

See the result of 1 hour work. I can load the Porto with a portable smoke cable chager.
And if not i put it in my dashboard box.

CQCQ abd im portable on D-star.

If you like to connect with a reflector on Dstar we know the usual way.

Unlink

YOUR:         U
RPT1: PI1UTR B
RPT2: PI1UTR G

Link to a new reflector

YOUR: DCS007 (x)
RPT1: PI1UTR B
RPT2: PI1UTR G

Linking to a reflector is done in the way above.

Resent i did hear that connecting to a reflector can also be done with DTMF.
As D-star is very new there is not much info on the internet about it.
Lucky i found some info on a few UK site about linking with DTMF.

Example:

DTMF commands

0 = Link Status
# = Unlink
*36A = Link to Dplus Reflector 36A
D502 = Link to DCS005B (UK National DCS Reflector)
D513 = Link to DCS005M (Midland DCS Reflector)

It’s still in the testing fase. But if you like to try it working on the dutch repeater Pi1UTR.
I have no idea if this works on any other repeater.

Another question is how does it work on my IC-E92D.

Just program it on the DTMF memmories. There are 10 places.
When you key the TX then press the number to send the DTMF code.

Example:

CHN01: *D701*

Press TX and hold it. Then press 1. Your IC92D will send *D701* as a tone slot to the repeater.
If the repeater know this DTMF code it will connect to the reflector you like to hear.

Ofcourse there are many  more dtmf tone slots. Look on http://www.xreflector.net/neu3/

Is Digital voice better then Analog that is the question?.

Digital voice is better in a way that error correction is applied in the system.  Now days we have the D-star network and connection to distance overseas is no problem anymore.
With internet as a helping hand the distance on VHf/UHF is no issue you can connect to any dirrection.

But what if we don’t have internet and only a point to point. What will work better. Ofcourse i had to find out.

In two different ways me and 2 other hams setup a sked with a point to point connection.
Analog to Analog and DV to DV.

Here is the outcome of the results with a distance of 3.5km.

We both used a setup inside the building and a hamradio station on the otherside of the village with a base setup.

– Analoge you need 25 watt with a external antenna to make a normal qso without to much noise.
– With DV you need only 5watt and a porto with the orginal antenna.

With DV the signal is even without any noise.

As a Dx hunter on HF it’s kinda strange to be a youngster again on D-star.

What a details you need to learn to see what is all happening on that kinda medium.
First i bought a IC92D porto.  I allready have a 2/70cm and HF tranciever so to have overkill with tranciever is not needed.

A porto is very mobile and can be taken with very easy to work or other places.

Ok where do you start. You need to register yourself on a repeater website. I’ve done that on PI1UTR.NL . After the registration i needed to send a copy of license.
Two days later i recieved a email that my account was ready to go.

The next step is getting the setting correct on the repeater and load a correct icf file to my IC92D. After changing the call and message i’ve updated my porto.
Everything was working but i did see on thing missing. I was not vissible on the reflectors. I’ve asked a few people but they could not tell me why. I’ve waited for two days. Maybe this has to update on the reflectors. Johan PA3GER remebered that a setting had to be done to get yourself vissible on the reflectors.

If found this explanation on http://ircddb.net/live-vis.html

**** HOW TO SET ****

VIS ON
“VIS ON” means “visibility on”. In this mode, detailed information about your transmissions (e.g. time, length and TX message) are shown in the “Live Log” and in the “LastHeard” list. This information is available on the Internet, and can therefore be processed automatically by other systems. If someone sees this as somewhat problematic, he or she might not want to enable this option.

“VIS ON” can be activated in a very simple way. Put “VIS___ON” in the YOURCALL field of your transceiver and press PTT once on a repeater which is connected to the ircDDB network. After that put something different in YOURCALL, e.g. “CQCQCQ__”. The setting “VIS___ON” will be stored permanently on the network. You only have to do this procedure once. You can check if this procedure worked by looking at the “Live Log” web page: http://ircddb.net/live.htm. Your call sign should appear from now on if you press PTT.

Example: local repeater DB0DF, module B

YourCall: VIS___ON
RPT1: DB0DF__B
RPT2: DB0DF__G

The character _ must be exchanged with a space character.

VIS OFF
“VIS OFF” means “visibility off”. In this mode, only the call sign of the repeater where you pushed PTT the last time is stored internally in the IRCDDB system. This is necessary for call sign routing to work properly. This information is only shared with other repeaters and is not visible on the Internet.
In the “Live Log” and “LastHeard” lists, your call sign will be masked, both in the MyCall field of your own transmissions and in transmissions made by others who might have used your call sign in UrCall. Your TX message will also be masked.

“VIS OFF” can be activated in a very simple way. Put “VIS__OFF” in the YOURCALL field of your transceiver and press PTT once on a repeater which is connected to the ircDDB network. After that put something different in YOURCALL, e.g. “CQCQCQ__”. The setting “VIS__OFF” will be stored permanently on the network. You only have to do this procedure once. You can check if this procedure worked by looking at the “Live Log” web page: http://ircddb.net/live.htm. Your call sign should not appear any longer from now on if you press PTT.

Example: local repeater DB0DF, module B

YourCall: VIS__OFF
RPT1: DB0DF__B
RPT2: DB0DF__G

The character _ must be exchanged with a space character.

Default setting: VIS OFF
The default setting is “VIS OFF” for all users. You have to enable visibility with the command “VIS ON” (see above) in order to appear on the “Live Log”. If you want to keep the default setting “VIS OFF”, you don’t have to do anything.

You can switch from “VIS ON” to “VIS OFF” and vice versa at any time.
