But i know what you mean. I have to install much solar power to be able to run the system 24/7 even in winter. So there is a LOT of energy which is not used in summer. That offers a big playing field... > Unfortunately Tx and grabbers are not compatible in a common site > Yes, a problem that i have here in the city. But now, this remote site is 3.5 km distant to the shack and TX antenna. But anyway it is overloading the RX. Theoretically i could transfer the data over a distance of 20 km when using 2 of this long yagis. There is enough SNR to lower the power here in the city... > But seems that you bought the whole forest, didn´t you ? ;-) No costs. I just officially asked for permission to mount the stuff there. It's for a research project of the university, you know... And who knows! 73, Stefan
