Hi Mal.

It would be very nice to have a 60ft vertical, you would not obtain permission where I live, 3m is the max without planning permission.

It is all inter related. But a few fundamentals are necessary. If it is so bad with for instance a 24 dB disadvantage I would MOVE or pack it in.

Too many excuses are used, the amateur has enough space for a reasonable antenna but says he is concerned about what the neighbours might think. I have heard this so many times. How much space does a 60 ft vertical take up, less than half a sq metre.

Surely when a radio amateur is looking for a property he has antennas in mind and looks for the largest real estate he can afford.

especially if interested in MF or LF.

So wspr is totally dependent on the Receive operator ? and a vy quiet location. I thought the whole idea was to overcome this problem

It is not working, as I said looking at the wspr database, some stns are not even aware that others are active because of lack of signal for what ever reason.

May be , may be not  Mal

 

The system is  reading  the  s/n   at the  Rx   and  not the   field  strength ........  depends on the  local  noise level ,   rst   159  or  599  , carrier  still  S9  ,   1= qrm     5= no  qrm

Example

I am receiving PA3EGO + 2dB another UK stn is showing -22 at a shorter distance. A difference of 24 dB

and this station says he is an Expert!!

One thing the wspr DB shows is how poor some Receivers/Antennas are comparing like with like approximately same distances from Transmitter.
