Phone Calls from Microsoft

I have had a spate of calls from Microsoft, usually an Asian sounding fellow who has my name and phone number.

Last Friday it went like this:-

Sir we have a report sent on line from your computer about a problem.
In my best East End Jewish accent (have you seen Face Jacker),…………. shouting. WHAT A WIRUS?
Yes your computer has reported a problem.
OH NO.
Sir I am from Microsoft your computer has reported a problem to us.
OH NO…..WIRUS?
No Sir it is not a virus, some stray electrons have entered you computer.
LECTRONS……OH NO.
Yes Sir some stray electrons have entered your computer.
OH NO…. I SEEN EM, LITTLE YERRA DEVILS TODAY I SEEN EM….OH NO.
Yes Sir, are you front of your computer now?
PUTER YES.
Sir what is your operating system.
YEH……….OH NO.
No Sir. what operating system do you have.
WINDAS
No Sir do you have Windows7 or Vista.
YEH.
No Sir which operating system do you have.
AHHHHH…WHERE IT SAY?……AHHHHH….OH YEH MICROSOFT.
No Sir, which Microsoft version do you have.
AHHHH… LEM ME SEE AHHHHHHH…….NIREEN NINY TWO.
At that the miserable swine hung up on me, pity, I wanted to know what it was like working in an immoral money grabbing ewiroman…..OH NO!
Each OH NO was so loud I could sense the removal of the phone from his ear with a pause to see if I had finished before his unusually gentle reply:-)

Radar – Aircraft Scatter – on 70MHz

A new situation presented itself this week in the way of VHF Aircraft Scatter on WSPR signals from Liverpool.

As there are no air lanes which cross our signal path I interpreted the limited AS that I was seeing as possibly takes off’s from Liverpool John Lennon Airport which rapidly went out of beam to the East.

No said G0MJI the planes definitely take off and land to the West. JL Airport is very close to G0MJI QTH and directly in line with our signal path. Wisdom from both ends said that Aircraft would be far too low to produce reflections. Such as this.

I hate to see the ‘experts’ who carefully gather all the evidence then find the maths that fits. I much prefer to do it like this.
Could the evidence possibly indicate reflections from Aircraft landing from East to West.
First the Aircraft Speed from the Doppler shift seen. This equates to 277.595kph. great this is Jet landing speed. In the observed period of Doppler shift the plane will travel 4.69km.

I now applied this information to the map, the reflection is remarkably symmetrical either side of the signal path. I could therefore measure a line 2.3km long from the East approaching the signal path. Next the rest of the 4.6km must be measured from the signal path to the West if this distance takes the Aircraft off the end of the runway then we are wrong.
Bingo, a perfect landing, we do get Doppler on 4m from low level aircraft landing in front of a distant station right down to ground level.

Of course the Speed computed is the maximum, from the maximum Doppler shift, this is seen to be less after the signal path is crossed which fits with a landing Plane. Therefore the true distance travelled after crossing the signal path will be less and that prior greater. I consider my method accurate enough to prove / disprove the theory.
