Filters

Nothing earth shattering here, just the same old way of doing it...
Find the source of the noise and 'cure' it at the source. Typically that means adding a 'filter' (capacitor to ground or inductor in-line). The 'other' way of doing it by shielding. Wrap the noise maker in foil! Yeah, right. Or just stay as far from that noise maker as possible. 'Nuther, yeah right.
A very large hammer almost always works too...

  • @ Geoexplorer69:
    Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
  • @ Geoexplorer69:
    Is 30 ohms worth worrying about in a 100’ run of rg8u ?
