Remember that album from Mike Oldfield? A user on YouTube found out that this album contains a hidden and unintentional CW message.

This was caused by a powerful VLF station located next to the recording studio, which interfered with the recording equipment. Because the signal is very weak nobody ever noticed it — until now.

The video below shows you how to receive VLF signals with nothing else than an antenna plugged into the microphone input of your sound card and SDRSharp to make it visible and audible.

The decoding of the the Tubular Bells signal is shown at 9:54.

This is a repost  of a posting made in 2009. It is still as true today as it was then.

I received an email a couple of hours ago to tell me that the Windows setup file for VOAProp is reported as containing a trojan at VirusTotal, so I checked for myself. It’s true. Thei nstaller is reported as containing a trojan by 8 out of 41 scanners none of which I have heard of or have any reason to take seriously.

I checked the original copy of the KComm setup file that I have here just in case my web site had been hacked and a trojan planted. But the result was the same. I also checked the downloads of a couple of other programs of mine including MorseGen and VOAProp. They produced virtually the same scan results as for KComm.

For years I have advised people that if they have downloaded a file from a source they would trust and their security software flags it as suspicious, they should scan it at VirusTotal to get a consensus of opinion as to whether the file really is a virus, a trojan or spyware, or just a false alarm. Unfortunately, VirusTotal has kept on adding new virus scanners to its armoury regardless of whether they are any good or not. The lunatics are taking over the asylum and as a result, VirusTotal has become useless as a tool for ordinary PC users to check whether a file is suspicious. I recommend jotti.org instead.

Some of my programs that are accused of containing a trojan were last updated several years ago. They have since been downloaded by hundreds or thousands of people. It is inconceivable that they could have contained a trojan that remained undetected all that time. The thing that all the programs have in common is that the installers were all created using the same setup generator. The likelihood is that somebody used the same setup generator to create an installer package for a trojan and the third rate scanners are picking up on something in the installer package that is not unique to the trojan.

I have no desire to waste my time contacting the developers of obscure anti-virus products to inform them about this false reporting of my programs. Nor do I have any plans to repackage all the programs using a different setup generator. I’m sorry, but third rate virus scanners are not my fault and I don’t have the time or the inclination to deal with the problems they cause. If you choose to trust your virus scanner instead of me  I won’t argue with you.

Some of the scanners are flagging the fact that the files have been compressed using UPX. This is a harmless tool used to make executable files smaller. It is not a malware. But I don’t know how users of these scanners are supposed to know that.

I’ve had a little V dongle for a while and it works as a reasonable receiver but is let down by my puny Atom based PC. It gives me the Norman Collier effect. So I was very keen to try out some software from Martin Marinov that lets you use your Android tablet / Phone that replaces your PC. Low and behold it works and at £6 is a lot cheaper that buying a new PC.

I have a Google Nexus 7 and you’ll need a way of connecting the device to your mini USB socket on the tablet but there are plentiful from eBay or Amazon for minute sums of cash. I suspect some may be better than others but if it works it works!

There is a stinge-ware version that has a few limiting features but I would recommend trying it out and paying out. Its only the price of a couple of pints!

The software sets itself up and downloads a driver (from the same developer). My first attempts had a few issues with the software not finding the device at first but a quick reset had it all ship shape in no time. All in all a great App and a lot less hassle than the SDR set up I originally had to do.
