Re: FSL Antenna Tuning Course Video

Les Rayburn

Thank you for taking the time to produce this training course for the use of FSL’s. Very helpful! 

One question I have that would only apply to DSP ultralights like the CC Skywave. Does the effect of narrowing the bandwidth of the receiver have any impact on tuning the antenna? What bandwidth setting were you using in the video? I assume the stock 6 KHz setting. 

Your craftsmanship is something to behold.

For the benefit of Todd, Paul, Chris or any other Oz (or worldwide) DXers who wish to try out a compact FSL antenna to track down exciting DX, a video showing detailed the tuning procedures for the getting the best inductively coupled gain boost from any FSL has been posted at

Three daytime DX fringe stations (on 620, 1070 and 1700 kHz) are tuned in on a stock CC Skywave and 3" Baby FSL, while the fanatical instructor shows you how to track down the best gain boost every time. The FSL antenna does have a reputation for being somewhat tricky and mysterious, but hopefully this tuning course will dispel some of the mystery, and prepare some DXers for an exciting new way to enjoy the hobby! Once you get past the Yankee accent the rest should be easy...
