Re: LF: Status 8270 Hz, 17 April 13

No, Peter, I didnt change the output pwr but the ERP may differ from hour to hour depending on how strong the wind is.
today btwn 40 and 80km/h with the result some top wires came down.  

I have to tx a almost phase stable signal so that Peter Nicholson can take his measurements.
but that doesn’t work with top wires (if complete) swinging 10m to the south and 10m to the north back and forth.

Hello Uwe,

Did your reduce power, or is it the rain ?

The signal did decrease dramaticaly since 16 April 13 as you can see.

That bright bar between 15 and 16 april is because I accidentaly did disconnect the Earth wire from the Mini Whip antenna.

That wire is connected between - of the Mini Wipe power input section and my central heating tubes here in the house.

It reduces the noise a lot as you can see in the spectogram's at www.qsl.net/pa1sdb

 

Now and then I'm playing with Spectogram zoom factor and collors as you can see :-)

 

Best 73's, Peter.

The TX will be back on the air when here in jo43sv the sky is blue agn.

Since weeks Paul Nicholson tries to receive the signs at Marlton/New Jersey in 5.8uHz width.
