    The wellgood active RX loop

    As you can see, I have used this quite a bit in the last week. It was
    designed by George Smart M1GEO after he accidentally cooked his Wellbrook active loop!
    Overall, it works very well, but I wonder if it is less good with weak
    signals on the higher HF bands. Mostly, EU stations are copied, but where
    the RX noise figure dominates, maybe it is less effective?

    Until I went on 20m at about 0900z, I was on 40m FT8 RX. Overall, the furthermost was FS4WBS (6632km). Once again, I was using the Wellgood
    active RX loop on the shack window.
