Stefan, The feeder is 10mm diameter stainless steel. I guess it takes at least 300A before it melts :-) So the limit would be the withstand voltage of the ceramic isolator, even on MF :-) Brings back

.. you should replace the stainless steel wire with an aluminium wire... lighter and with lower losses... in this way you could improve the signal and I'm sure that Markus will listen to you also via

Hi Marco and John, For some reason i didn't receive John's answer on the topic, odd. John, thanks for the story. Well, it wasn't my idea to use a steel wire. It was rather a construction engineer who

Hi Eddie, Yes and it is not new and it has all been done in the past :-) The feeder is 10mm diameter stainless steel. I guess it takes at least 300A before it melts :-) So the limit would be the with

Hi Stefan Did you look to see if your feeder had taken one hour to melt? :-) You know that WSPR's auto reporting is of no use at all and the quick QSO Mode 599 imi 599 is the preferred method. 73 Edd

MF, I just see that there was a lot of TA DX last night, however local signals in a range of 300 km were very poor! Could it have to do with the elevation angle of the radiated signal, so that a flat

Stefan, et all... 4000 meters was dead last night so I tried 630. Strange that only one decode on the Continent [France]. All the other decodes were UK stations even though many Euro stations monitor
