Finally had time to build a VHF Bandpass for my cheap HT cross band relais. Filter is based on DG0SA. Maybe I should go with a higher order filter but for the first quite ok. BTW: the #libreVNA is ufb

Today #LibreVNA helped convince a colleague that the ancient HP VNA was in fact right and the Superlinse cavity was indeed detuned. ;-) #GSI

The top half of the image shows two large cylindrical structures, left green, right orange. In the middle of the first section of the orange cylinder, blue cables are attached to two outlets. This first section is called Superlinse.
The lower half show a concrete pedestal, a rack mounted controller and a laptop in the foreground. Behind the laptop is a small metal box to which lead the blue cables. The box is the #LibreVNA and on the laptop's screen the software shows measurement results.

Oh yeah, just received the new #LibreVNA and checked it out really quickly. Nice device, nice software. Maybe, if I find the time, there'll be a blog post about it.
