VNA Sweeps

  • VNA SWR Sweep of PennyWhistle - done with miniVNA Pro.
  • (For these sweeps, specifically, I was following the instructions in the assembly manual:

(If you are concerned about your proper assembly of transformer T1, an easy check is to connect an antenna analyzer, such as an MFJ-259 into the input connector (powered off) and you should see a VSWR below 1.5 from 1.8 MHz to 50 MHz, dipping down to 1.2 or lower around 10 MHz.)
