UPDATE: I got the dipole resonant in the 80 meter band. The resonance frequency was far beyond the 80 meter band. I shortened the wire of the 80 meter part and I was successful. It is for 80 meter an antenna with a very narrow bandwidth. Between 3700-3710 KHz I do have a SWR of 1,2:1 Between 3690 and 3700 KHz SWR 1,5:1 and also between 3710 and 3720 KHz. On 40 meter the SWR is 1:1 between 7025 - 7145 KHz. Perfect so to say.
This morning I had a sked with Adam M6RDP. A could receive him with good signals between 57 and 59. Sometimes QSB, but most of the time it was OK. After the sked with Adam I worked MØIME Martin also from Torquay, UK (just like Adam) with CW on 40 meter.
