Hi Markus,
I live in a 15 floor building, on top of which there is a 30 meter mast, and my building - by Warsaw standards - is "small". (I set a QRP world record in 2005 from such a building on 3.5mhz)

Many amateurs have access to far higher objects (:

Thus to hang a dipole on such a building would not be expensive and to mount a 1w TX at the dipole center point would make beacon construction simple.

My concept is to have a "real" beacon that would act as a marker of propagation, but when I look at WSPR I wonder if such an idea is outdated and the era of traditional beacons is over?

Hi Richard,
 
a 100 m high and 300 m long antenna... sounds like an expensive way to generate just 1 W ERP on MF ;-) I'd just love to have one, but I'd rather use it to expand my VLF capabilities.
 
Regarding a "traditional beacon"  - wouldn't BIA (474 +- 1.02 kHz) fulfill just that?
 
Best 73,

Hi,
If a chance arose for a powerful traditional MF beacon in Poland would it be of interest, or has WSPR done away with the need for traditional beacons?

By powerful, it would be meant the full legal limit (1w!) into a half wave dipole mounted high above ground level (minimum 50m, but possibly in excess of 100m).

Your thoughts gentlemen

73s
