HendiMy #FifiSDR (actually built at THAT Fichtenfieldday) is revived w/ quisk. Unfortunately the original repository is gone. Good old TH-F7 hooked up to #T2FD just gave me the first signals from the belgian #BRAMS beacon on 49.97 MHz. (130 W, radiating straight up). Approx. 325 km, but no classic definitive meteoscatter burst signals yet.
Attic mounted #T2FD hooked up to
#nanoVNA. Doesn't look bad, worst SWR just below 3:1. Antenna has mains cables nearby, I tried to break those up with common mode filter ferrites into segments <2.5 m, so less than 1/4 wave at highest freq, and at the entry points to the attic to supress cm propagation to other areas and import of noise from there. Worked quite nice for swling, might accept transmissions from me too. #hamradio #
