SOTA

2015-08-27T08:34:38Z

Tom:

Summits On The Air is an amateur radio award program. Basically it´s about hiking up the mountain with radio equipment, setting up the station and making connections to other operators on various bands. It can be challenging and is great fun!

There is also the [http://www.cqgma.eu/ GMA program] (Global Mountain Activity) that accepts SOTA logs and lists additional summits with special GMA references. The GMA site provides some more statistics and got a nice mapping feature.

= Links =
* [http://www.sota.org.uk/ http://www.sota.org.uk/] - Official main SOTA website and starting point
* [http://www.sotamaps.org/ http://www.sotamaps.org/] - Map of SOTA summits world wide
* [http://sotadata.org.uk/ http://sotadata.org.uk/] - Site for logging, statistics and summit lists. Full access requires registration.
* [http://www.sotawatch.org/ http://www.sotawatch.org/] - Monitor current and upcoming activations

= Logbook Sheets =
Here is my current version of a SOTA/GMA logbook. It should also be useful for GMA, WWFF and other activations. It holds up to 25 QSOs and provides plenty of space for notes. All important data is noted on top, easily for the operator to find while in QSO with chasers.

Installing xtables-addons on Raspbian

2015-01-09T22:42:28Z

Tom: /* Get the xtables-addons source */

=Why?=
Annoyed by tons of SSH brutforce attacs, I was looking for a way to lock out connections coming from other countries than the desired ones. [http://xtables-addons.sourceforge.net/ xtables-addons] got the ''geoip'' module which enables us to use rules like
<nowiki>iptables -A INPUT -i wan -p tcp --dport 22 -m state --state NEW -m geoip ! --src-cc AT,DE -j GEOIP_BLOCK_LOG</nowiki>
This example would match on connections not originating from Austria (AT) or Germany (DE).
I wanted to use it on a Raspberry Pi running [http://www.raspbian.org/ Raspbian].

=How?=
Raspbian, a Debian based operating system for the Raspberry Pi, is a bit different to other Debian distributions when it comes to add kernel modules. The Kernel sources can not be installed using the packet manager but are downloaded and set up by a separate tool.

==Getting the latest kernel and sources==
* Update to the latest kernel and firmware using the '''rpi-update''' script as described [https://github.com/Hexxeh/rpi-update here].
* Reboot the Pi
* Download and install the kernel source using '''rpi-source''', see [https://github.com/notro/rpi-source/wiki rpi-source].

==Install packets from the repository==
<nowiki>sudo apt-get install libtext-csv-xs-perl geoip-database libgeoip1</nowiki>
Other tools might be required. Please tell me if anything is missing here.

Debain How To´s on that topic describe the use of ''module-assistant'' for making the kernel modules. I did not succeed using it on Raspbian!

==Get the xtables-addons source==
On the 9th of January 2014, with Raspbian kernel version 3.12.35+ and iptables version 1.4.14, I decided to go with xtables-addons version 2.5.

Download it from [http://sourceforge.net/projects/xtables-addons/files/Xtables-addons/2.5/ SourceForge]. Then unpack it, configure it, make it, install it:
<nowiki># in some nice location, eg. the home directory, do:
tar -xf xtables-addons-2.5.tar.xz
cd xtables-addons-2.5
./configure
make

# if everything went fine, install it:
sudo make install</nowiki>

You can disable unneeded modules by editing the file 'mconfig' and speed-up the process.

'''Or''' be lazy and use the pre-compiled modules for '''kernel 3.12.35+''': [http://tomelec.net/files/20150109_xtables-addons_raspbian_3.12.35+.tar.gz download]

==Download and build the geoip database==
As root (sudo -i):
<nowiki>mkdir /usr/share/xt_geoip
cd /usr/share/xt_geoip
/usr/lib/xtables-addons/xt_geoip_dl
/usr/lib/xtables-addons/xt_geoip_build -D . *.csv</nowiki>

=Final thoughts=
* Feel free to delete the leftovers of ''rpi-source'' (~/linux-....tar.gz). You might also want remove the xtables-addons build directory.
* There are no automated updates when using this method! If the kernel is updated, xtables-addons needs to be rebuilt and installed. Geoip database updates have to be done manually or via a custom cronjob.
* Have fun with xtables-addons on your Pi!

Hyundai HLT-3270 Repair

2014-10-18T22:21:06Z

Tom:

I recently got a 9 year old HLT-3270 32" LCD TV and thought it would be worth fixing.

''The following describes what I did in order to get the TV working again. I´m not an expert on this. Use this information on your own risk. Think about what you´re doing before removing any screws and take full responsibility for it. Note that there are dangerous voltages present within the device, even minutes after it has been plugged off.''

= The Defect =
TV will not turn on, no power LED on, no current draw on the mains supply. Mains fuse on the power supply is open.

= Power Supply BP-170AWL =
This set uses a ''Bentek DMC BP-170AWL'' power supply according to the sticker on the circuit board. I was not able to find schematics on that particular board. It provides only 12V and 24V to the TV main board and backlight converters and the output pins are labeled.

'''Key parts:'''
* '''PFC controller:''' Fairchild FAN7527B
* '''PWM controller, switch''' Fairchild FS7M0880
* '''Diode for PFC''' STTH8L06 (assumption)
Datasheets can be easily found. The FS7M0880´s application note ''AN4121'' ist particulary interesting.

The TV can simply be powered by applying 12V/1A and 24V/5A which I tested with lab power supplies. That could be an option if the original PSU cannot be repaired.

<gallery>
File:Bentek BP-170AWL.JPG|Power Supply (after swapping some caps)
</gallery>

I tested the rectifier, diodes, the PFC´s FET, and the power switch for shorts. All capacitors where at least not shorted. Then I supplied PFC and PWM controller with an external supply voltage and found the current draw of approx. 20mA ok. After replacing the fuse, I slowly powered up the device with a 60W light bulp in series. It turned out that the power supply tries to start up, fails and retries several times per second.
When measuring the PFC controller´s supply voltage with a scope, I found it really unstable, rippling between 12 and 25V.

= Solution =
The instable internal supply voltage was caused by a defect capacitor: '''C19''' 100uF/35V. After replacing that one, the power supply got in some more stable state.

I then checked further caps and found all ''Samyoung'' branded ones out of spec. In the end I did replace:
* C13 47uF/35V
* C14 1uF/50V
* C19 100uF/35V
* C32 1uF/50V
* F1 T3,15A

Again, these caps were all dead or got far less than their original capacitance!

No semiconductor parts were obvious damaged. I did not care about most of the capacitors on the secondary side - although they are ''Samyoung'' types and might not be in good condition too.

After the repair, the set works fine again. The power supply got a standby power consumption of approx. 10W which appears a bit too high. Possibly there is still something wrong with the standby/burst mode?
