hpr2403 :: Amateur Radio Round Table #3

Released on 2017-10-18 under a CC-BY-SA license.

This is the 3rd in the Amateur Radio Round Table series.

Participants in this episode are:

  • Steve, KD0IJP
  • Michael, DL4MGM
  • Ken, N0CALL
  • Russ, K5TUX

No agenda items had been set before recording, so we spent our time answering Ken's questions and allowing the discussion to proceed naturally. Some of the topics of conversation included:

  • What the licensing exams are like in the US as well as Germany.
  • Resonance.
  • Antenna design.
  • RF Modulation

The next Amateur Radio Round Table recording is tentatively set for November 15, 2017 at 18:00 UTC. Watch the HPR email list for any further updates on this and consider joining in the discussion if you are a "ham" or if you aren't but have any interest in the subject.

hpr2358 :: Amateur radio round table #2

Released on 2017-08-16 under a CC-BY-SA license.

This time only the two of us:

  • Steve, KD0IJP
  • Michael, DL4MGM

A lot of off the cuff technical explanation.

Starting from the comment by David Whitman to the last round table, we talk about frequency, wave length, propagation velocity and their relations. Approximate wave length values are commonly used to reference to entire "frequency bands", which are the frequency spectrum portions allocated to a certain radio service in proximity. Status of (amateur) frequency allocation may vary with band or country. They may not be "exclusive" and there can be "primary" and "secondary" radio services sharing that spectrum. Secondary services must not interfere with primary ones, while the other way round has to be accepted.

What frequency is most powerful? - It depends! We ramble a bit how different frequencies have different propagation depending on certain factors like daytime, time of year, sun spot cycle. - Please help out with more in depth information here! Join us. There is a varying maximum and a minimum useable frequency for ionospheric propagation.

VHF (globally > 30MHz) and UHF (> 300 MHz) waves have a more line of sight propagation. Steve shortly introduces the concept of repeater stations. Usually at an exposed location, a repeater retransmits the signal that is received at another frequency, thus extending communication range. Participants only need to reach the repeater in order to be able communicate with each other. We hint at additional propagation modes for VHF, like sporadic E-layer propagation, but are not able to go into detail. - Please tell us, if you have experience in those fields!

Some thoughts about RF output power and how it is less important if conditions are right.

Modulation: Putting "information" onto a radio frequency signal. Staring out as a clean "carrier wave", its parameters are modified according to the modulation scheme. We start out and explain the basic concepts of amplitude modulation, AM, where the amplitude of the radio wave is altered by the modulating signal. Then frequency modulation, FM, where the modulation process influences frequency of the output signal. We use voice audio as an example as modulation content, but this can of course be of digital nature. SSB, single side band modulation. It is the standard voice modulation mode for short wave amateur communication. We give a very brief explanation of one possible way of generating it. We discuss how it is more efficient than AM in regard to occupied frequency spectrum use and transmit power.

This leads to ideas how great it would be if someone could record a show about those things, including audio examples. We further digress in how it may be a good idea to single out individual topics separate shows. The "rabbit holes" (tm MrX I think) we fall in while explaining other stuff. Make them available to be simply referenced in later shows and we can concentrate on the topic at hand.

There will be a place to put ideas and draw inspiration for shows here:

Next we pick up the discussion of frequency shift caused by the Doppler effect and its effect on satellite operation. This was triggered by a question in "hpr2216 :: Working AO-85 with my son" (

We ramble a bit how in the wide field of amateur radio no one can know everything right from the beginning. Take the jump start provided by the knowledge required for the test and go on with learning by doing.

How cool would it be to have shows from "Ham fests" like the "Dayton Hamvention", the "HAM RADIO" or any other event. A brief mention of the "ARRL Fieldday".

We have a mini poll and want to get feed back from the audience, if they would be interested to have some sort of decoding riddle in future shows.

After a short introduction of the hosts, we start discussing the question that came up on the mailinglist:

How do you get started at all? How do you get the license to participate in amateur radio?

Probably the amateur radio organisation in your country will provide the essential information required for obtaining an amateur radio license. Start looking at the International Amateur Radio Union at and track down your country. From there you can search for information about your local area and local groups. In the US, look for the ARRL at

If you do not chose to get involved with the local club before taking the test to get the license, we suggest you do so after that. Local events and clubs can provide the insight into the vast possibilities amateur radio has to offer. This will allow you to chose much better, where your personal interests are and where to start. Radio "nets", are mentioned as a good starting point to actually get "on the air" and to overcome any possible shyness.

Acronyms explained along the way

  • VFO: Variable Frequency Oscillator. The thing behind the main tuning dial to adjust the frequency, an important building block of radio equipment. In modern gear the VFO-mode is the mode where you can continuously change the frequency in certain increments, as opposed to memory mode, where you normally select from a set of fixed frequencies previously stored.
  • CW: Continuous Wave. Used to reference to Morse code telegraphy as an operating mode.
  • VHF: Very High Frequency. Generally this references the frequency range 30 Mhz to 300 MHz. In the context of a radio user, it normally means the sub range in there, that is assigned to the specific use.
  • UHF: Ultra High Frequency. 300 MHz to 3 GHz
  • HF: High Frequency. Range 3 MHz to 30 MHz. Also referenced to as "short wave" frequencies. Several amateur radio "bands" are spread out in that frequency range.

We often reference frequency ranges by wavelength. E.g. the "20m band", which is the frequency allocation for amateur radio at 14 MHz. The connection is: Wavelength = c / frequency, with c being the speed of light. A rule of thumb is: Wavelength [m] = 300 / frequency [MHz]

Hint: The manufacturer Tektronix offers a nice poster with the world wide frequency assignments worked in:

We went on describing a bit where our personal interests in amateur radio are.

Our combined interests cover all the way from Morse code over voice communication to digital modes and "foxhunt" (the radio sport of Amateur Radio Direction Finding). Note that there are many other facets to amateur radio. Even our combined interests are just a small segment of the possible activities within the avocation.

We talk about getting started with just listening to amateur radio traffic on the short wave frequencies.

Why do you need a license, why not just do it?

First, without a license, it is ILLEGAL.

Law makers have acknowledged that one important goal of amateur radio is education and experimentation. We are allowed to modify equipment or even build it completely from scratch and operate it legally on the assigned frequencies. This is a unique privilege that sets amateur radio apart from any other radio users which have to use certified equipment.

We give some amateur related podcast recommendations, among those: Linux in the ham shack ( and HamRadio 360 (

The Next Edition of the Amateur Radio Round Table

Next ham radio round table will be held in about a month, with a time that will be better suited for European time zones. We welcome anyone to participate, whether or not you are a licensed ham. Watch the HPR email list for announcements and details.

hpr1738 :: Credit Card PIN breach

Released on 2015-04-01 under a CC-BY-SA license.

On September the 10th, 2012 an anonymous malicious hacker released 10,000 pin codes onto the site paste bin dot com. How the attacker gained access to the codes is not known, but it is thought that it may be linked to a breach that occurred at the end of March 2012 to the Credit card processor Global Payments. That attack exposed 1.5 million consumers financial data. These codes have been confirmed by security experts to be legitimate and in wide spread use even today. Despite this exposure been "common knowledge" among the security community, major banks and credit card companies have yet to issue any statement on the breach.

Tired of waiting for action by big business, we bring you a list of the codes so you can check for yourself if your data is compromised.

hpr1504 :: HPR at NELF 2014 Afterparty

Released on 2014-05-08 under a CC-BY-SA license.

In this episode, Members of the HPR community, and attendees of NELF share their thoughts about the 2014 Northeast GNU/Linux Fest. Sorry for the dynamic range of this one. I levelled it out the best I could. Also sorry for getting this out so late. RL has been kicking my ass lately.

Some interesting things that were mentioned that may be worth checking out: The NELF talks and website:

The Zoom H1 Recorders are fantastic devices, and we need to thank the HPR community for chipping in to buy one. They definitely pick up more sound than I did when the podcast was being recorded. I heard things in playback that I wish I had heard and addressed during the live recording.

Thanks to Richard Stallman for the lyrics to the Free Software Song

Thanks to The GNU/Stallmans for their performance of the Free Software Song on the RevolutionOS documentary.

We all had a great time recording this show, and we hope you enjoyed it as well. Please join us at the next Northeast Gnu/Linux Fest if you can. Thank you very much for listening.

Sincerely, The HPR conference crew

P.S. Some people enjoy finding mistakes. For their enjoyment, we have included a few.

hpr1477 :: OSI layer 3

Released on 2014-04-01 under a CC-BY-SA license.

In today's show we continue our look at The OSI model for network communications, with examples of Layer 3 been given with particular focus on Geography diverse Host addressing.

From Wikipedia:

In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers, whereas the data link layer is responsible for media access control, flow control and error checking.


The network layer provides the functional and procedural means of transferring variable-length data sequences from a source to a destination host via one or more networks, while maintaining the quality of service functions.

Functions of the network layer include:

  • Connection model: connectionless communication
For example, IP is connectionless, in that a datagram can travel from a sender to a recipient without the recipient having to send an acknowledgement. Connection-oriented protocols exist at other, higher layers of the OSI model.
  • Host addressing
Every host in the network must have a unique address that determines where it is. This address is normally assigned from a hierarchical system. For example, you can be "Fred Murphy" to people in your house, "Fred Murphy, 1 Main Street" to Dubliners, or "Fred Murphy, 1 Main Street, Dublin" to people in Ireland, or "Fred Murphy, 1 Main Street, Dublin, Ireland" to people anywhere in the world. On the Internet, addresses are known as Internet Protocol (IP) addresses.
  • Message forwarding
Since many networks are partitioned into subnetworks and connect to other networks for wide-area communications, networks use specialized hosts, called gateways or routers, to forward packets between networks. This is also of interest to mobile applications, where a user may move from one location to another, and it must be arranged that his messages follow him. Version 4 of the Internet Protocol (IPv4) was not designed with this feature in mind, although mobility extensions exist. IPv6 has a better designed solution.

Within the service layering semantics of the OSI network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.

  • Greetings to small region of U.S.A. and 2 more Honolulu, Rarotonga, Adak, Papeete, followed by a short reminder of the ORCA fundraiser.
  • Can a short url be thought of as time based
    • I maintain that in it's current likely implementations that it is not.  Especially since it is likely that the storage uses a 1 original URL to many shortened URLs.  However, I would think it would be possible to implement as a hashed function given the rights seeds.
  • KuraKura: questions about using mumble.
  • General conversation
  • Discussion about Orca and handling integration with various software packages.  Ken wants to motivate the HPR community to explore the issues that exist, and talk with developers from application projects about improving their orca integration.
    • JonDoe mentions that there might be dependencies and / or regressions that occur as changes are made due to hacks / workarounds that currently exist (both in orca and applications)

And surely ye’ll be your pint-stowp!
and surely I’ll be mine!
And we’ll tak a cup o’ kindness yet,

We twa hae run about the braes,
and pu’d the gowans fine;
But we’ve wander’d mony a weary fit,
sin auld lang syne.


We twa hae paidl’d i' the burn,
frae morning sun till dine;
But seas between us braid hae roar’d
sin auld lang syne.


And there’s a hand, my trusty fiere!
and gie's a hand o’ thine!
And we’ll tak a right gude-willy waught,
for auld lang syne.

hpr1184 :: Installing Linux without a monitor

Released on 2013-02-14 under a CC-BY-SA license.

Two weeks ago we aired a show about the Sonar Project which is a specialized GNU/Linux distribution to develop and proof accessibility in a modern distribution. This is a test bed and so every single enhancement and discovery will be sent back upstream so that all distributions will be accessible by default.

The Sonar Project show was downloaded a total of 14,219 times so far and yet only 127 people have donated.

Today it's a case of the blind leading the (simulated) blind as Jonathan Nadeau walks pokey through an install of the Sonar GNU/Linux distribution without a monitor.

So listen along and experience what life is like if you are a blind hacker.
Press PAUSE to hear what it would be like if Jonathan had not done so much work already.

hpr1025 :: Infonomicon Episode #51

Released on 2012-07-05 under a CC-BY-SA license.

Syndicated Thursdays is a chance to showcase other Creative Commons works. We try to expose podcasts, speeches, presentations, music, etc that you may not have heard. If you have suggestions for items then send your recommendation to admin at hpr and we'll add it to the queue.

Today we are going to listen to episode 51 of the infonomicon ( ) podcast. Droops had been a regular listener of RFA and emailed their show several times, started his own show Droops Radio which changed to infonomicon radio.

Infonomicon Bumper Music plays until 1:35. Positive feedback about the Infonomicon TV. This is episode 51, which should be almost a year, except it's been more than a year. Podcast Incubator 2.0 is coming, and its code is going to be released under the GPL. Dosman and Droops have come up with the idea of doing a daily radio show: Talk with a Techie (TWAT). No fluff, no nothing, at least five minutes long. Infonomicon won't close because of this. Obfuscated is not a happy camper, but he is alive. 16 of 66 pages in a magazine Droops read was from one magazine. Bob Denver (Gilligan) passed away, and the boat from Gilligan's Island was named after a FCC chairman. AOL is about to be a sucker again, so screw them over. Cyber-looters are registering domains and taking money from hurricane donators: 2500 domains have been registered. Droops is not sure what the solution should be and asks for solutions. People trust Google, but Google can do evil: they're an advertising company. Google is buying dark fiber. Google has all sorts of broadband needs, so they'll likely go after all sorts of bandwidth to bring their services. Droops wishes that Google made blogs an option to not search. There's lots of companies searching nothing but blogs. This hasn't been the greatest show ever, but work is being done on the other shows. This is the shortest Infonomicon ever. Bumper Music plays from 15:42 onward.

Udev Source To Be Merged Into Systemd tree

Kay Sievers, lead developer for udev, announced on the Linux hotplug mailing list plans to merge the source code for udev into the systemd tree. When this happens systemd will continue forward using the udev version number, so it will jump from 45 to 184.

After the merge it will still be possible to build it for non-systemd systems. He went on to say that builds of this nature will be supported for a long time to come. This is necessary so as not to break systems with initrds that lack systemd. Distributions that do not want to adopt systemd can build as they always have except they will need to use the systemd tar ball.

The decision to merge the two projects was based on the fact that init needs to be completely hotplug capable. Making udev’s device management and knowledge of device life cycles integral to systemd. This makes this merge a change in build scheme not a change in direction or interface. This leaves the libudev API untouched.

So what all of this boils down to after the brouhaha settles down is that in essence nothing really has changed.

Google Glass, Jetpacks Must Be Just Around The Corner

I have been a fan of science fiction since I could read. Well everyday reality seems to be catching up with the science fiction of my childhood. If you have not seen the video yet head on over to YouTube and check it out:

These are the kinds of things we geeks have been saying are coming since we were children. They are so futuristic that I am still having a hard time believing that they are actually in testing.

The Internet rumor mill has been swirling around this for awhile now. Google calls it Project Glass and it is being developed at Google[X], Googles R&D laboratory. The announcement on Wednesday, 4/4 about field testing for Google Glass was released in a post on Google+ ( It is however for Google employees only. The designs shown on Wednesday are just a selection they have more including one that can be incorporated into your existing eyewear.

The biggest questions raised by this announcement have already been answered. Those questions being, won’t these get in the way of reality, and, won’t these just separate us more from from real life, well according someone who has used these, in an interview with the NY Times, the answer is no:

“They let technology get out of your way. If I want to take a picture I don’t have to reach into my pocket and take out my phone; I just press a button at the top of the glasses and that’s it.”

The glasses do have a unique look about them, and people will know you are wearing them right away. They will hopefully get smaller and be able to be integrated into a regular looking pair of glasses.

I don’t care if these are impractical or don’t work I want a pair of these right now. This is the science fiction stuff I used to dream about when I was a kid. How far away are the personal jetpacks.

ICANN Writes A How To For Governments To Seize Domains

Coming to you directly from the “Not Cool” department. It was pointed out to ICANN that it was providing a disservice by not speaking out against governments seizing domains. So what does ICANN do? They publish a white paper that is basicly a how to for governments to seize domains. They have also made public statements that they will work closer with governments to help them seize and censor domains. This unfortunate turn of events just further illustrates the uselessness of ICANN to protect the Internet. It instead shows how they are actively undermining the very principals of the Internet.

IBM And Red Hat May Join OpenStack

From the I made this up to sound important bag. GigaOm reports that IBM and Red Hat are joining OpenStack. Neither company nor OpenStack has confirmed this report. OpenStack was started about two years ago as joint effort between NASA and Rackspace. Since its inception it has grown immensely with over 150 companies and 2,000 developers. I do not know how much cache these two will bring to the party however as the list of companies already includes the likes of HP, Dell, Intel, AMD, and Cisco.

OpenStack released the fifth version of its software this week code named Essex. They are having a Design Summit April 16-18 in San Francisco. This could be where new partners will be announced.

April 4, 2012. KDE released updates for its Workspaces, Applications, and Development Platform.

Significant bugfixes include
* making encryption of multiple folders using GPG work,
* XRender fixes in the KWin window and compositing manager,
* a series of bugfixes to the newly introduced Dolphin view engine
* improvements in the Plasma Quick-based new window switcher,
* Kontact and its device counterpart Kontact Touch have received a number of important bugfixes as well as performance improvements.

KDE Tooltips— when is too much, too much? Well for me when it’s associated with KDE tool-tips
Despite the fact that I am a big fan of KDE, there is one thing that annoys me every time I install a KDE-based distro—the numerous tool-tips and pop-ups that appear in an attempt to be helpful.

Recently while searching for some KDE information, I found that someone else also had expressed similar sentiments and went on to list all of the tool-tips that he had disabled. His version of KDE was 4.5—but it had not changed too much for 4.8.1. Here are the various tooltips that I have deactivated.

System Settings tool-tips: Are you bothered by KDE displaying the list of items for each configuration category within the System Setting area: Disable it thusly:.
1. Open System Settings
2. Select the Configure button
3. Uncheck the “Show detailed tool-tips”
Icon-only Task bar tool-tips: If you’re using the icon-only task bar, you will appreciate this information instructing how to suppress task bar pop-ups.
1. Right-click on the task bar.
2. Select Icon-only Task Manager Settings
3. In the Appearance section, Select “Do Not Show” in the tool-tips drop-down and save.
Panel balloon pop-ups: Do these balloons make you want to blow up? Selecting this option will suppress the pop-ups that appear when you hover over shortcuts and icons on the desktop.
1. Open System Settings
2. Select Workspace Appearance and Behavior
3. Select Workspace Behavior
4. Select Workspace
5. In the Informational Tips widget, select the “Do not show” option.
Title bar buttons (Maximize, Minimize, Close):
Open System Settings
Select Workspace Appearance
Select Window Decorations
Select the Configure Buttons button
Uncheck the “Show window button tool-tips” check box
This feature appears to be broken on my desktop—no tool-tips either way, plus my extra buttons with spacing are not appearing on the title bar. Perhaps my just downloaded and installed upgrade to 4.8.2 will fix this problem. ;)
Dolphin: Stopping the mother of all pop-up tooltips…This action prevents Dolphin from taking the content of the information panel (which can be set to appear on the right side) and repackaging it as a tool-tip..a very large tool-tip This may come in handy for some people, but for me it was over the top.
1. Select the Settings menu
2. Select the Configure Dolphin… option
3. Select the General tab
4. Uncheck the “Show tool-tips” check box.

LibreOffice: The tool-tips that appear when you hover over the tool-bar will disappear.
1. Select Tools, Options.
2. Under General, uncheck the Tips box.
