Logger: N1MM+ most updated version
Station: Yaesu FT-817ND - 2,5W
Antenna: 84m horizontal square loop on 7m AGL.
CW decoder: FLdigi & CWskimmer
Did you know there are HAMradio operators that are using contests for experiments? Oh yes there are, I know that for instance PA1B Bert is using the contest to experiment with QRPp (extreme low power) just to see what is possible. Others do study propagation with the help from RBN. And I did experiment with some decoding software. Last year I used Fldigi and MRP40. This year after much trouble I managed to install CWskimmer to test.

Another thing I used this time was a NIR-10 DSP audio filter between the radio and computer because I don't have any small filter in the FT-817. Together with the bandpass filter from CWskimmer I think it did well supressing nearby signals from other stations on a incredible busy 40m band. All this was a great experiment and I learned the only thing left is to purchase CWskimmer and get a decent digikeyer to work on CW. I learned CW just generated with a soundcard is not good enough. Though still it is a miracle that I was able to make such a amount of contacts with only 2,5W and inperfect gear.
Complicated....yes! |
