Kytoon - Helium balloon and kite
Testing the setup for future vertical HF antennas. Wind was lite, so not an option for kite only flying. Balloon only flying (with payload of 100g) was not stable and in danger of going into the low trees (6-7m high). Kite plus balloon was very stable and at excellent height. Additionally the system was generating considerable lift (not measured but maybe around 200-300g). Definitely this is the setup to be used for lifting antennas in lite to moderate wind. It combine the best of both worlds.
Wind: 5-8 km/h
Balloon (Gemar 85cm, weight 25g) inflated with pure helium to 65cm in diameter (payload lift 135g)
Kite: 80g, 80x90cm

    If I don't want to use the audio from the SDR (just using the Transceiver audio), can I set the delay so Full Break-In (QSK) is working from the Transceiver? For the Panadaptor SDR application, I don't really care if the SDR display can't follow the Receive audio while sending CW (it will switch in the SDR after I stop sending). Also, since the two SO-239 connectors are wired together should the Antnna Switch safely handle 200 Watts of transmit power?
