HamVoIP via FritzBox

(This post is a dutch about HamVoIP as it is mainly of interest for Dutch Ham Radio users.)

Sinds september 2022 is het mogelijk gemaakt dat gelicenseerde radiozendamateurs elkaar contact kunnen onderhouden middels VoIP telefonie.
Dit syteem is operationeel onder de naam "HamVoIP". Ook zijn er conference bridges en een aantal radiostations die via HamVoIP beluisterd kunnen worden.
Op https://hamvoip.nl/ is hier meer info over te vinden, onder andere hoe een aanvraag voor een HamVoIP nummer gedaan kan worden. Ook staat hier info hoe dit op een aantal telefoontoestellen geconfigureerd kan worden.
Zelf het ik (PD1LAB) ook een nummer aangevraagd en gebruik dit via mijn FritzBox en hierbij mijn instellingen. (Een aantal gegevens zoals mijn wachtwoord en wat telefoonnummer cijfers heb ik onzichtbaar gemaakt.)

Ik had zelf al eerder met voip geexperimenteerd en ik heb daardoor al meerdere voip verbindingen op mijn Fritzbox.
Mijn HamVoIP verbinding was terecht gekomen op   *121#  (waarschijnlijk omdat een nummer had verwijderd en dit weer beschikbaar werd.

[ *124# is mijn normale vaste verbinding (en dit heb ik ook als default verbinding ingesteld) ]

Het invoerscherm bij aanmaken van nieuw telefoonnummer:

In eerste instantie had ik bij de gebruikersnaam mijn roepnaam ingevuld. Het bleek echter dat ook hier het telefoonnummer moest worden ingevoerd.
HamVoIP blokkeerd trouwens na 3 foute inlogpogingen gedurende 60 minuten de toegang. Daarom duurde het iets meer dan een uurtje voor mijn toegang echt werkte.  

Onderstaand de gegevens zoals zichtbaar in de FritzBox bij controle:

Bij klikken op het pennetje bij het telefoonnummer worden deze gegevens zichtbaar

Quansheng K5 ( Intro & Chirp )

The Quansheng K5 plus and K5(8) has 200 memory slots to configure station names, frequencies and other settings. 

This is the first of a series of posts about changing or adding frequencies (or other other setting) in this Quansheng K5 memory slots. In this and my upcoming posts i will use the word "Quansheng K5" however i only have the K5 plus and K5(8). Probably it will also work using a K5 or K6. 

You can change frequency settings on the radio itself or copy the frequency list from one Quansheng K5 to another. Also it is possible to use your Quansheng to do a scan and used a received frequency as a new entry. However another easy and common used method is using some computer software to edit and create the frequency list. (This process is also called creating a code plug).

I am no expert on this and there are many tutorials about this topic. However i want to share some of my experiences with some software.

You need to connect your Quansheng K5 to your computer. Most times this is done using a programming cable. There seems also to be plug with Bluetooth that you can put in your radio, however i have not seen using the Bluetooth plug with a Quansheng.

Problems often reported are

  • Not pushing the plug firmly enough in the radio. There are even posts about people who scaped of some of the plastic of the radio to make the plug fit better.
  • Not having the correct USB driver for the cable.
  • Not having the radio in the right mode. (See several tutorials, different things needs to be done for uploading new firmware  or upload/download settings.)

To load and edit the channels several software is available. In this post some info about one often used program.

Chirp

Chirp also connects to some databases with frequencies and when installing it also puts some frequency lists in the install directory.

I used and tested "CHIRP next-20231016 on Python 3.10.8 wxPython 4.2.0 msw (phoenix) wxWidgets 3.2.0". The Chirp software can also be used with many other radios. (Unfortunately not with my Anytone 878 UV III).

The Chirp source code can be found on GitHub and often a new releases are made available.

There is much information available including YouTube instructions from people who know the Chirp software better. See their instructions and watch their videos as most can explain it better than me. 

Chirp screenshot 
Besides editing the frequencies in Chirp it is also possible to import and export this information to a *.csv file. Unfortunately i could not find all the fields that i see on the screen in this export *.csv files.  Especially the settings for the scan lists that can be edited in the program. I also tried the 'Show extra fields' and the  'developer mode'. This also limits the possibilities to do some of the editing in Excel. 
Several other settings of the Quansheng K5 can also be edited in Chirp and it is possible to load and save all the settings using a  *.img file.

There are some items in Chirp that could be improved;

  • Copy and past of multiple items.
  • Better editing possibilities.
  • Import and export of all columns including the scan list information.

however Chirp is a great and relative easy to use program.

My Quansheng K5 radios

Currently i have 3 Quansheng K5 radios.
The Quansheng K5 radios are relative cheap and nice to play with (when you know and keep to the rules, e.g. being a licenced Ham radio operator).

The first one was a Quansheng K5 plus. It did not have a USB (emergency) power port however it included the USB data cable.
Therefore (and to do some experiments) i did buy second one a Quansheng K5(8) that had the USB emergency charge connector.
Later i did win a third one in a lottery. This is also a Quansheng K5(8),

On the outside you can easy see the difference between the K5 plus and the K5(8). Besides the (missing) USB emergency charging connector and the color of the display, there are some easy to see differences. My two Quansheng K5(8) radios look exact the same.
The Quansheng K5(8) has some metal screws on the front and the speaker area looks different. My two Quansheng K5(8) have an orange volume on/off knob and my Quansheng K5 plus has a black knob. My Quansheng K5 plus has a colored M and Exit button and a metal shining Quansheng logo. Also some other small differences between are visible.

As i do experiments with all of these radios it would be nice to make the two Quansheng K5(8) radios a little different. For example at the moment i have loaded different software on each of these radio's.
Until now i could only see the difference as i did not add the belt clip on my last Quansheng  K5(8). However today i must say the looked exact the same as did a little hack to see the difference more easy.

The new situation :

Radio

Metal screws

Knob

K5 plusNoOrange
K5(8)  YesOrange
K5(8) "second"
(december 2023)
YesBlack

The italic values (black and orange) in this table are not the original values:
I swapped the black 'volume on/off  knob' from my Quansheng K5 plus with the orange knob of my newest Quansheng  K5(8) radio and now they are all more different from each other.

Mini 2 port RJ45 Network switch

Some remarks about the mini 2 port RJ45 network manual switch in my mailbag 2023 Q4-4 post
Why did i not use a normal switch or router so i could connect two network devices at the same time.
Yes if you want to operate multiple network devices at the same time other (most times better) options are available!
However i did buy it for special applications.
The manual switch is relative cheap (i did pay Euro 3.45) and can also be used for other things  

You can switch anything that goes over the wires, not only network (using an adapter to RJ45). Also you get a real physical separation of a device when disconnecting. Below some more picture of this device.
