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 withstand voltage of the ceramic isolator, even on MF :-)

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.

I find it interesting to see that the propagation on 630m between JN49 and JN64, just 563 km, changed so rapidly and consistant from a non-decode to an SNR of 0 dB, i.e. by about 30 dB in one hour!

At EA2HB we can see now daily when the band opens from DL to EA and when it closes. A really useful software!
