Dear Walter,

I guess You should feed your energy-saving bulbs from the mains via a
current balun of at least some hundreds of microhenries when running
your transmitter!

HW?

Dear All on MF, 
          DI2AG is still running in WSPR, 0.5W ERP on 505.090KHz. TNX to
G0HNW for his numerous reports last night and also to F4DTL and DJ6LB.
DI2AG will be transmitting continually throughout day and night until
Monday morning. Your reports - also daylight propagation - are welcome
via WSPR database or by e-mail. Thanks a lot.

BTW: Last eve, when I started WSPR on MF, I observed my signal with ARGO
- full band view. Only one modulated carrier on the screen. All ok. For
a while later - sun had disappeared - suddenly the screen was full of
vertikal lines , all modulated like the main carrier. It was a ladder,
all lines 100, 200, 300,.....Hz apart. When the transmitter paused, the
carriers were off. Something wrong with the equipment? After a long time
I found the reason: I had switched on the light in my shack. This comes
from three energy-saving bulbs, each 15W. My antenna begins just outside
the shack, part of the power mixed in the electronic of the bulbs with
the rectifiers. When replacing these Bulbs by good olds type Mr. Edison
the ghost carriers were off. What do we learn? Before saving energy test
the bulbs for curious signals :-)
