SSN data file goes AWOL

I've not updated the VOAProp file ssn.txt for a while as some irritating health issues kept on getting in the way. I thought I would have a try today butit seems the NOAA data file Iused to update it from  has moved to a new address. Does anyone know where it has gone to?

Chromium plated

I never did find out what was causing Google Chrome to crash so much on my computer. However, after several months of using Chrome I found Firefox rather slow and clunky. So I had a look round to see if there were any other browsers. It turned out that there were more alternatives than I ever imagined.

The first alternative browser I found was one called Avant. This is a powerful browser with a lot of configurability, developed by a Chinese programmer. It boasts the ability to render web pages using your choice of the Internet Explorer, Firefox or Chrome rendering engines, which is probably handy if you're a website developer. I set it to use Chrome and it displayed the pages that had give me trouble with nary a murmur. But I found the user interface rather heavy after the minimalist approach of Google Chrome. So I kept it on my hard drive but carried on looking.

The next candidate I stumbled across was SRWare Iron. It almost counts as two browsers in one, as it installed two shortcuts on my desktop, one named SRWare Iron and one named Chromium, both pointing to the same executable. This turns out to be a browser built from the same open source code as Google's Chrome by a German company. Germans seem to be a bit sensitive about privacy, so the main difference with this SRWare browser is that it does not send information about your browsing habits back to Google. What, you didn't know Google Chrome did that? Neither did I until I discovered this program, though I thought I opted out of this during Chrome's installation.

Apparently you can opt out of all the Google tracking if you choose the appropriate settings in Chrome, but most users won't do this. So Iron / Chromium could be said to be a better version of Chrome than Google's, certainly from the privacy point of view. Chrome extensions like AdBlock Plus work as with the real thing. Chromium even supports the ability to log in to your Google account to save and restore your bookmarks and other settings, which was very handy.  Try it, you'll never notice the difference.

I'm happy with Chromium / Iron as my default web browser now. So far, it hasn't crashed on me. But I also discovered another Chrome clone. It's called Comodo Dragon and it's made by the Comodo security company. Dragon is also built from the Chrome open source code and omits the Google tracking code, but it     has some extra security features added by Comodo. So it looks like an even better option if you are really privacy-conscious.

Back to Firefox

Goodbye Chrome. It was fun while it lasted. But in the last day or so Google Chrome has become so crash-prone that it is unusable. Suggested solutions amounted to disabling plugins and add-ons but my installation was pretty basic apart from AdBlock. Nevertheless I took the step of uninstalling Chrome completely and then reinstalling again. But it still crashes. Just trying to sign in to Yahoo is enough to crash it.

So it's back to Firefox. I don't have time for flaky browsers.

The LinkedIn virus

I'm still getting the repercussions from the lapse in attention which resulted in LinkedIn sending invitations to anyone who has ever emailed me. Most people have just deleted or ignored them. A few were concerned that the email might have been a virus and contacted me to ask if I really had sent it. But now LinkedIn is emailing everyone who didn't reply with a message saying I'm still waiting for them to accept the invitation.

A few people have been annoyed by these emails and have asked me to stop sending them. Unfortunately the deed was done a few weeks ago and I have no idea how to put a stop to it. If I had known that it was going to cause this much hassle I wouldn't have even considered accepting someone's invitation but hindsight is a wonderful thing that I unfortunately don't possess and now there is no undoing it.

An Aaargh! moment

Some of you may have received an invitation to join my LinkedIn network from me today. To those who accepted, thank you. To those who found the invitation unwelcome, I apologize.

It was not my intention to spam you in any way. Unfortunately I didn't look carefully enough at what was displayed so that instead of emailing just those whom I had painstakingly selected from the list, the invitations went to all of the hundreds of addresses in my Gmail contacts list.

It was a real Aargh! moment, but by the time I had uttered the exclamation it was too late! Judging by all the invitations I have received in the past from people I don't remember, I don't think I am the first person to have done this.

New Yahoo! group for JT9 mode

It was inevitable this would happen: someone has started a Yahoo! group for the JT9 mode. Pity they couldn't have made it a Google group like the one for JT65A but I guess more hams have Yahoo! accounts than Google accounts.

There was already a fairly quiet WSJT group but this will keep the discussions about using JT9 on HF separate from the rather esoteric MS and EME stuff.

Hacked off

This is not much to do with radio. But I know that many of you have your own websites and will probably find this of interest.

A couple of days ago I discovered that one of my websites had been hacked. Not G4ILO's Shack, but the other one which still continues to earn us a little bit despite receiving only the barest maintenence in the last two years.

I opened one of the pages and instead of the expected content a server error message appeared. My first thought was that the hosting company had changed some setting so I fired off an urgent support ticket. They responded saying that some of my files had been "compromised". Sure enough when I looked at one of the files there was some code I didn't recognize. This code referred to a file that had been added which was zero length, and that was causing a 500 server error. I deleted the file and every access now caused a 404 "file not found" error. Eventually I found that the .htaccess file had been hacked and some code added which was being executed for every single file access.

The timestamp showed that the .htaccess had been modified a week ago on 19th March. Because of the web browser caching we had not noticed the error messages any earlier. Google had visited the site in that time however, and had received a server error for every page it tried to access. So now the site had dropped out of Google. Thanks a lot, hackers.

Further investigation revealed that the hackers had modified almost every .php file on the server. They had inserted some code at the beginning of every file, apparently meant to disable error reporting. They had inserted some other code into one .php file that was included in every page. However, something in what they had done had the effect of disabling PHP processing with the result that the PHP code was sent to the browser instead of being executed.

To cut a long story short, after trying to repair the hacked files individually, I decided to restore the site from the oldest backup the hosting company held. I had a little bit of luck: the oldest backup was taken on 19th March, the day of the attack, but it had run before the attack occurred so I was able to restore the site with every file as it was originally. A day later and that backup would have gone and I would have been unable to restore the site without a lot of manual work. But the damage had been done as far as Google was concerned.

If you are expecting a lesson to be learned as a result of this story, I don't have one, other than if you want a quiet life stick to blogging, don't try to run your own website. If you do, visit your site every day and check for changes.

I have no idea how the hacker managed to gain access to the files on my shared web server. If they did it once they could do it again. I don't believe that my passwords were compromised as they are randomly-generated, but I changed them anyway. Altogether this episode lasted for several stressful hours - time that I would much rather have spent trying out the latest WSJT-X program.

DXMaps needs your support!

The DXMaps website run by Gabriel EA6VQ needs your support. This is the site that plots contacts spotted to the DX Cluster on a map, band by band, to show propagation in real-time. It is especially invaluable during the summer Sporadic-E season to track the rapidly-moving band openings.

DXMaps plots DX contacts band by band in real time

The trouble with any web site is that if it becomes very popular the costs of running it grow beyond what most people can afford as a hobby. According to EA6VQ the cost of a new dedicated server for the site will be $250 a month. So he is asking users to become "supporter users" by donating $33 US per year. But any donation is welcome.

If you are an active operator, especially on six metres and up, you will know how invaluable DXMaps.com is. Hopefully hams will step up to the plate and send Gabriel a donation.

New page for JT9 modes

JT9 just got even better. Thanks to Laurie, VK3AMA, JT9 has a new page to show current activity or general chat at hamspots.net.

As far as I can tell, the spots are generated from the spots to PSK Reporter, which the latest WSJT-X program does automatically if you tick the appropriate box. So you don't have to do anything extra for your spots to show up on this page. This is a great facility that I am sure will increase the growing popularity of the JT9 mode.

Fix for "Gmail app unreachable" in Google Chrome

This morning when I started up Google Chrome and tried to log in to Gmail the page kept coming up "Gmail app unreachable". Curiously, when using Firefox Gmail loaded up fine.

I found a solution to this issue that works for me. Right-click the shortcut that you use to start Google Chrome, then on the Shortcut tab in the box marked Target which contains the full path to chrome.exe, append a space followed by  --ssl-version-max=tls1 (that last character is a number 1.)

I have no idea what this does but as I say, it worked for me.

YouView or not YouView

This post is nothing to do with ham radio. However it is about radio - or rather TV - and the internet, and I'm pretty sure some of my readers know more than I do about this subject.

Here's the thing. A few days ago TalkTalk - our telecoms and broadband provider - sent us a letter offering a free YouView box as a sop for the tariff going up. If I understand correctly, a YouView box would provide us with two things that we don't currently get from our plain old Freesat box: the ability to record programmes (our Freesat box isn't one with a hard drive in it) and the ability to catch up on already broadcast programmes using things like BBC iPlayer.

If we want to watch programmes after they have been broadcast then we have to use iPlayer or whatever on our computers, of which we have about six in the house already, not counting the old Toshiba laptop I run DOS on to program Motorola radios or the other slightly less old Toshiba laptop that has a whole column of dead pixels in the middle of its display. I haven't tried connecting one of the computers to the wide screen TV in the living room and watching BBC iPlayer that way. We watch it on the computer screen if we want to. If we want to record programs for later viewing we need to buy a newer more expensive version of our Humax Freesat box.

A YouView box would cost £299 so it's quite an attractive deal to get one free. The question is: would we be able to use it without a lot of hassle?

If I understand correctly, in order to use a YouView box we would need two things that we don't already have: a digital terrestrial TV antenna (we get all the TV channels we need on Freesat) and an Ethernet connection to our router accessible from where the TV is (because apparently YouView doesn't have a wi-fi adapter.) Obtaining these would entail a fair amount of extra expense on hardware (i.e. the cost of having a TV aerial installed, and some kind of wi-fi adapter or a long and ugly piece of Ethernet cable.) Nor do I know whether YouView would need the same type of TV input already being used by the Freesat box, namely the HDMI input.

So my thinking is that it's not worth the cost and hassle. Getting stuff like this to work usually results in my tearing my hair out - and it's only just started growing back! But then I'm not the one who cares if we miss Strictly Come Dancing because we are out or some other show that clashes with something else we're watching. Perhaps I shouldn't look gift YouView boxes worth £300 in the mouth. Your thoughts, multimedia experts?

WSPRnet issue with Chrome

Has anyone else noticed that when you open the map page at wsprnet.org in Google Chrome the sliders (the bit you drag to scroll up/down or left/right) are missing from the scroll bars? They still work if you drag on where they ought to be, but as they are invisible it's a bit confusing.

QRZCQ Update

I have just uploaded a couple of new images to QRZCQ.com, the new ham radio database site.

If you wondered where the nice QSL images in recent blog posts came from, I took them from those ham's profile pages on QRZCQ.com. I thought it was a good idea to use a QSL image for the page, so I scanned one of my printed QSL cards and uploaded it to my own profile on the site. You are allowed two pictures, a main one and a secondary one, so I uploaded a photo of me in the shack for the secondary image. It's good that the site developers allow decent sized high resolution images.

Somebody will probably take me to task for stealing images from a web site. But in my opinion (for what that's worth) a QSL image should be okay. If I received it from the bureau what's to stop me from scanning and uploading the image of cards I receive? I'm just anticipating receiving it. :)

I have also uploaded my contact log to QRZCQ.com. That was a simple matter of exporting the log to an ADIF file from KComm. The most up to date copy of my log will always be the one at G4ILO's Shack, though, because that is taken directly from the off-site backup copy of my log, uploaded automatically whenever I close KComm.

Poor conditions

Propagation is really poor at the moment. Never has my WebProp propagation widget been quite so accurate. On 10m WSPR I am hearing nothing and no-one is hearing me. On 30m APRS it's just as bad. I'm not picking up a single packet.

I opened WebProp's page in Google Chrome and noticed that the small format widget had a vertical scrollbar on the right hand side. I thought I could remove it by adding a few pixels to the iframe height attribute but it didn't seem to make any difference. I think a bug in Chrome might be causing this. The presence of the scrollbar reduces the width of the table causing several lines to wrap and making the table taller.

I found that the scrollbar was eliminated by adding the attribute scrolling="no" to the iframe definition. If you are using WebProp on your website I recommend you do the same. If you aren't sure exactly what to do then go to the WebProp web page. The code examples have all been updated with this extra attribute.

I recommend you to do this even if you don't see the scrollbar in Google Chrome. That will prevent it from appearing in any web browser.

Farewell Firefox

After many years as a stalwart Firefox user I have today made Google Chrome my default web browser.

I had tried Chrome once before. It was probably too early a version as I could not get on with it and missed too many of my Firefox extensions. Since then I have grown less dependent on those extensions and Chrome has become compatible with or has gained alternatives to those I need.

I installed Chrome a second time in an attempt to solve a problem that I thought was an issue with Firefox and turned out to be something else entirely! The installation was quick and easy. Chrome imported all my Firefox bookmarks with ease, reminding me to close Firefox so it could access them. I didn't allow the installer to make Chrome the default browser initially, but after half an hour I was ready to take the plunge.

This won't be news to those of you already using Google Chrome but the new browser feels much faster than Firefox. I see that 20% of visitors to G4ILO's Shack are using the Chrome browser. I think it won't be long until it overtakes the 27% of my visitors using Firefox.

No-IP Free

A few months ago I began using the No-IP Free service in order to be able to access my home network using a hostname or  fixed IP address. This worked well until a couple of weeks ago when I started getting the error "no host". I logged in to No-IP and could find no reference to my account. So I recreated it with the same details and it is working fine again.

I vaguely recall seeing something to the effect that to keep the free account active you are supposed to log in once a month. The trouble is I find it hard enough remembering what day of the week it is never mind something like that. Previously I had used the DynDNS free service but that didn't like the frequency with which my broadband changes IP address. My broadband provider says that I can only have a fixed IP address if I have a business account. It would be cheaper to stump up $20 a year for the No-IP Enhanced account. But being a dyed-in-the-wool cheapskate I'd like to avoid doing that. Any recommendations for free IP services that stay working as long as you want?

Is my web site down?

My website G4ILO's Shack is currently down. It appears to be down for everyone, not just me.

Sometimes a site appears to be down when it's really a problem at your end. There's a really useful site you can use to check if the server is down or not. It goes by the memorable name downforeveryoneorjustme.com. It's worth bookmarking, especially if you have a website of your own.

I've opened a support ticket with the hosting service. Hopefully my site will be back up by the time you read this.

Site changes

I've just spent half a day when I could have been working 10m DX updating the website and blog templates. The main difference is that I have made all the text about 10% larger, which should help those - including myself - who find small print increasingly hard to read.

I have also made the main content section wider so it makes better use of the screen. Most people have bigger monitors than when I first started G4ILO's Shack, from which the blog inherited its template. I dare say there will be a few using older, smaller screens who will find this change annoying. Sorry.

I have taken advantage of this change to include larger pictures and screenshots. Another benefit - though some may question that - is that I can use a wider ad format, which Google has been pestering me to do recently. I'm sure that some of my readers would have liked me to get rid of the ads altogether. However, they make far too much money to simply forgo it - not enough to live on but certainly enough to pay for my hobby and G4ILO's Shack's web hosting.

I wouldn't advise anyone on the basis of this to start publishing Google ads on their own ham radio sites or blogs - not unless you have G4ILO's Shack's level of visitor traffic. The ClustrMaps widget at the bottom of the left hand column will give you an idea how much that is, if you're interested.
