“Hurricane Irma’s effects are starting to be felt here in Central Florida, and the effects of the X8.2 class solar flare have begun to subside. 12 year-old Faith Hannah (AE4FH) decided to check into the Hurricane Watch Net to give a report. Right now, we still have power and the winds are not too high, so Faith Hannah used the 1/4 wave 20 meter vertical that is made out of a Crappie Pole fishing rod that we installed in the back yard when we took down our antenna farm. (We will be posting a video about that antenna shortly…) Later this evening, the kids will attempt to check into the Hurricane Watch Net with the Alpha Loop antenna that is indoors.”
