Title: Help! Low count in My Flights
Post by: GreekSpy2001 on January 06, 2010, 08:55:55 AM

Hi all

Trying to diagnose whether i have a problem. Live near LHR and my My flights is only 17 at present (0851 gmt). Now there is a blank of snow over everything so its it just the weather causing the low number of returns? Anyone in SE UK online can comment on the number of flights they are receiving?

In the past I was receiving regularly in the 80's around this time of day.

Concerned that I have a aerial problem or my box has the problem.

THanks

Graham

HI Just plugged in the Airnav supplied aerial and the count is just the same. So it is either a true reflection of the flights at the moment or my system has a fault. The reason I ask is since I upgraded to 3.13 have have noticed that I rarely have more that 50 flights showing. In the past this was normally in the 80s.

This just maybe the time of year and I know not very scientific but had a feeling this were down compared with before.

So anyone online near LHR at the moment?

We had a system in London which we regurally watch and during last nights heavy snow it was very intresting to the see the affect on the reception.

While the RB there usually picks up aircraft 100ft after departure at Heathrow it struggled to pick them up at 1000ft when a band of heavy snow was across Heathrow.

Interesting. My outside aerial casing is covered in snow. Would this have an effect?

Yes. It will totally de-tune the antenna and will reduce its efficiency.

Thanks Jeremey. Not getting the ladders out to clear it off.... (its on the eves of the house) too much snow and ice. Will have to put up with it for now until it thaws.

Hi Graham / All,

As a quick check, go to:

http://www.radarvirtuel.com

- you can zoom in to your area, and compare what is showing on there with what you have.

Cheers
