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 have just received my first telemetry from the FUNcube satellite, a.k.a. OSCAR 73. It was a piece of cake, one of the easiest things in ham radio I have done. What helped make it easy was that I was using a FUNcube Dongle Pro as the receiver (thanks, John!) . The FUNcube dashboard software supports it out of the box. No drivers to install or soundcards to configure. It was a piece of cake.The Dongle automatically tunes to the right frequency.

Of course, the whole project has been designed to be used by teachers with no previous experience of this kind of stuff. So you would expect it to be easy for a seasoned radio ham!

The FUNcube Dashboard software

The whole thing went something like this:

1. Download and install .NET Framework 4.0 from Microsoft.
2. Download and install FUNcube Dashboard from http://data.funcube.org.uk/
3. Register your call at the FUNcube data warehouse https://warehouse.funcube.org.uk/.
4. Download, read and follow the instructions (PDF files) from the FUNcube site.
5. Connect dual band colinear to FUNcube Dongle.

Sit back and wait for a pass.

 I was not present when the satellite went over as I was downstairs having lunch.

There are no suitable passes over this location this evening or tonight so I will have to wait until tomorrow for another try. Unfortunately apart from an FT-817 and the dual band vertical I don’t have equipment that can operate 2m ans 70cm so I’ll have to leave tryi ng to work through the transponder to someone else.

A surprise package dropped through the door yesterday afternoon. (I do like surprises!)  It was a SOTA Beams desk stand for the Elecraft KX3, customised with my callsign.

SOTA Beams desk stand for Elecraft KX3

In the absence of instructions and with the aid of a couple of the photos on the SOTA Beams website it took my poor brain a couple of minutes to work out how it went together. Actually there are a couple of self adhesive rubber feet and a length of edge trim the purpose of which are still not entirely clear to me.

The stand is robustly made from a laser cut  perspex type material and holds the KX3 at the perfect angle for desktop use.  (I’m not sure how that would be with the KXPD3 paddle. I didn’t try it as with my shaky hands I can only send dits at the moment. 🙂

This stand is exactly what I have been looking for to hold the KX3 when operating sitting on the ground with the rig beside you. The viewing angle is just right for that too – much better than standing your nice radio on the damp and dirty ground. The bright orange of the one SOTA Beams sent me  (they are also available in black or red apparently) makes the stand highly visible and so less likely to be accidentally left behind on the summit or other operating spot.

The perfect angle for desktop or portable operation

Thanks, Richard! This is definitely going in the case with the Alex Loop ready forwhen  my health improves enough for me to take a radio into the Great Outdoors again.

With  smoothed sunspot number of  282 nd a solar flux of 177 we are continuing to enjoy great conditions on the higher HF bands. I can’t remember the last time the sunspot number has been that high – though that joins a long list of other things I can’t remember either. I’m surprised that more bloggers haven’t commented on it – they were happy to spread gloom and despondency when the predictions said that this solar cycle ws going to be a dud.

I’ve spent most of my operating time on my favourite mode – PSK31. Truth is, I’ve always felt more comfortable at the keyboard than in front of the mic. But I really should try to get some time in on phone while conditions are this good. Who knows how long it will last?

WebProp– my solar weather web widget is proving to be a bit of an embarrassment with its prediction that HF band propagation will be poor. The algorithm clear places too much emphasis on the effect of high A and K index values.It would be better for users to use the condx=no option which will show only the raw ininterpreted data.

Conditoins remain excellent on the 10m band. I made several contacts and even had Stateside DX stations reply to my CQs. Two of my contacts were with Elecraft K3 users – don’t often hear K3s on digital though they are the perfect rig for it.

When I’m not actively working stations I like to look at the PSK Reporter reception reports map.  It’s more interesting than WSPR as the reports are of actual PSK31 signals. It’s a pity there isn’t a beacon mode because you have got to transmit or call CQ to see reports of your own signal. At least it is motivation to actually go on the air rather than just lurk!

Take a look at this diabolical interference on the 10m WSPR frequency.

Fortunately it doesn’t seem to affect decoding too much. The PSK31 sub band is free of it too.

This afternoon I ventured on the air for the first time in several weeks. Indeed it  is the first time I’ve felt like switching on the radio since my brain tumour removal operation. It was not entirely a good experience.

I thought I’d try digimodes since I would only need to click a few buttons to complete a QSO. But I found the whole experience a bit bewildering. I made two contacts on 20m thinking I was on 10m! And a couple of times I left the other guy waiting for me to send something.

About the only way I can describe how I felt is “out of it” – the phrase sometimes used to describe a person who is so drunk that they don’t know what they are doing. Only unfortunately in this case the demon drink was not to blame.

Somehow I think it is going to take some time for things to get back to normal.
