As Mrs. Doubtfire might say #amateurradio #hamradio #hfbands were "Wicked, Wicked, Wicked" due to #geomagneticstorm but at least I could test recent #km4cft 9:1 unun build & #randomwire with @youkits #hb1b into ATU-10 Autotuner on a beautiful 1st full day of Spring in the U.S.

Purposely took my #FT817 / #Z817 to use with my #KM4CFT 9:1 UNUN and Random Wire to my Antenna Proving Ground during pretty bad #HFband conditions. I had a short 20M CW #MorseCode #QSO with LJ #KI5GTR. Since it worked today, it will work under most any condition. HOORAY!

This one for a #RandomWire antenna with #HB1B 40 - 15 Meters. $1.00 Cosmetic Case does the trick to carry antenna and transformer
