Hello, here Andy F6CNI.
Please Sorry, when I am receiving on MF 500 kHz band, using my new PA0RDT active antenna, I have often some problems with incorrect spots coming...
Please consider that last 5 days this calls was wrong : 1V1UG T35NIY 9Q5ID O1AFS.
I do not understand what happened. But one thing is sure : I was not changing Band and I have not this problem with my others Rx antennas (80m long LW and a K9AY).
On the way, Happy new year to all.
