ON0MON back online

ON0MON back online

The repeater is back operational and working perfectly. There are no more Raspberry Pi for me; even if the repeater is experimental and subject to outages, it should not be for an unreliable hardware. Raspberry Pi are good for playing with and for home applications, not for a 24/7 repeater.

The server is now a Intel Xeon running at 3GHz with “just” 4GB Ram and a 64bit Operating System.

Ah… just because you spent your time reading this post, here is a teaser: soon there will be some big changes, so now, more than before, stay tuned! 🙂

Unexpected outage – Work in progress

Unexpected outage – Work in progress

The first Raspberry PI broke a week before the winter holidays, luckily I had a second Raspberry PI and so by simply swapping the memory card I was able to restore the repeater in a couple of minutes.
Today the second Raspberry Pi decided to stop working so I’m moving everything on a spare computer I have but it will be based on Windows due to some hardware incompatibilities with Linux.

So, ON0MON is work in progress, expecting to be back no later than tonight, 1st Feb 2015.

Stay tuned.

100% Service UP

100% Service UP

Holidays are over and everything is back operational.
I’m considering to shutdown this website, quite useless as there are no real feedback and no real benefits and move to the more common Facebook platform. Twitter accounts are already setup…

Hey you two people (spammers excluded) out there that are reading this blog time by time: if one day it will be unreachable try again after a couple of days, if still unresponsive means I shutdown the website. 🙂

Back Online

Back Online

There are some religious holidays ongoing so also my brain is on holidays, let’s make this quick:

– ON0MON D-STAR Repeater back operational, connected to DCS011 D (French); People are free to de-link, re-link, play, etc with the repeater, I don’t care unless it is misused.

– ON0MON APRS iGate,Digipeater back operational collecting your path and messages.

Happy season holidays.

It moves!

It moves!

Let’s make everybody’s life easy:

– Repeater D*Star ON0MON will be down for a couple of days; The equipment are going to be installed in a larger room in the same building. Cabling and installation will take for a while;

– Repeater,iGate,Digipeater APRS ON0MON will be down for a couple of days; Reason is the same for the D*Star Repeater.

– Website if bumping, I’m moving to another provider, to make a long story short, after a “migration” the site went offline. After trying to recover the site and data I gave up and moved to a web hosting service in France. Several pictures went lost, database (lucky me) are safe.

Happy Season Holidays.



ON0MON APRS is back online. I tried several different APRS applications but none of them was working really good on the second Raspberry Pi. Most of them were simply too entangled in configuration and connections. All the examples and experiences I found online are based on the audio modem configuration. Well I bought a real TNC so I can’t see the point to use a USB dongle instead of my TNC, but no one posted an example on how to use the software with a KISS-like TNC.

Now ON0MON D*Star Repeater is working extremely well, amazing configuration and the server is up and running non-stop since several days.

APRS is back on a Windows machine Atom-based with 2 GB of RAM and 64GB SSD Harddrive running APRSISCE/32, exactly like it was a week ago.

Happy New Year.

D*Star Up, APRS Down

D*Star Up, APRS Down

During the last days the D*Star repeater was having some strange behavior by looping itself and dropping the connection to the DCS011 which is the default hub. I did some investigation and I realized that the Windows version of the software are having problems.

Now the repeater is running on a Raspberry Pi version B using the exact software but Linux version and seems to be a little bit better stable but still having issues with DCS011. In fact it drops the connection and tries to connect every minute. The beacon announces the connection to the DCS but in fact it is not connected. It isn’t something which happens very often so it can be that the problem is located somewhere else, such as the Internet connectivity, the DCS itself… who knows… Investigation ongoing.

The APRS instead is now partially (not) working. The computer in charge to run the D*Star software is offline and the APRS system is setup to act as a digipeater only. No iGate capabilities at the moment. I’m planning to setup a smaller PC running just the APRS software. It is a waste of resources to run a quad-core server with 8GB of RAM just for the APRS. I have a small Foxconn Atom which should suffice the requirement for the APRS iGate and Digipeater.

Tomorrow is another day.


ON0MON Activation

ON0MON Activation

As I wrote on the previous message, I’ve been for three weeks roaming around Europe. So I went back and I just recalled the fact I gave the postal box key to a friend in order to collect the mailing a couple of times per week. There were some leaflet and some envelope in the mailbox but I decided they could wait for a couple of days, till monday to be read (and bills get paid).
Today the friend show up at my house, he notice the truck parked at the common parking lot and understood we were at home, so he brought the mailbox key to us with the mail (and bills).

One envelope caught my attention, it had BIPT on the top left side of it… I knew what was inside but I had no strength to open it… my son told me I had a big smile on my face while I was staring at the envelope and he become curious about the content as well.

It is the repeater license for ON0MON and I’ve been granted APRS and DSTAR capabilities!

I conducted some tests with my call sign for a certain period but everybody was saying the repeater permit and call would take over a year to get granted, so I was not in hurry to setup everything and I was considering the infrastructure as testing equipment.

So I started the APRS Gateway, changed the call and password and now ON0MON is operational on 144.800 for APRS operations.

The DSTAR capability will take a couple of days before being operational. I setup two different DSTAR repeaters, one is based on 2x Motorola GM900, UHF duplexer/cavity, embedded power supply and DVRPTR V2 board OLED Display version, max power 25W.
The second one is based on a modified 2x Standard C-5608 + Dutch Star GPSK Modem + 35A Switching Power Supply.
Both are feeding a vertical antenna on top of 15m tower.

Frequencies for the DSTAR Repeater are:

Frequency: 439.1375 MHz
Shift: -7.6 MHz

Someone once stated I decided to stay on the wrong part of Belgium… well, it looks like something made that assumption to be wrong and I’m pretty sure he will be happy to be wrong on that statement. 😉

I’m thankful to the UBA for the support they are providing in order to activate the repeater, a special thanks goes to Filip ON4PC (UBA Repeater Manager). He is doing a tough job and language barriers are not helping the management of the structure. We had some arguments in the past and I hope they were constructive for our activities.

There are vendors, VENDORS  and 5-Star HAM RADIO Operators 

Probably you already notice I like to buy two, three times the same device, I mean not the same product/firm/brand but devices doing the same job, made for the same purpose.

I bought some time ago (see below or use the search) a TNC and I had a very bad experience with the vendor… the device itself does the job in a very nice way, I really like it but I decide to give a try to another TNC, so I did some researches and found John W2FS, offering a PIC based TNC, the TNC-X.

I got in touch with John, asked a lot of question, requested information for the proper configuration, and ordered the kit complete of the box and audio connector.
