The kite was up in the air for > 24 hours without a break. I even went to bed (tent) while it stayed up :-) But of course it depends on the wind stability. That kite can carry 300m of wire , you know. There is a smaller version called 'power sled 24' which is maybe even a better choice when the wind is strong and the string is short. Looking forward to your first transmissions. 73, Stefan PS: A kite CW QSO on LF, that would be fine!
