Hello Mal,

Thanks for your tips to prevent the loadingcoil from overheating, this will
be usefull for those who can get 10A or more into the antenna.

Just one remark :

Dont waste all those hundreds of watts heating up your coil, send it up the
antenna.

Cooling the coil will not get a mA more into the antenna. The power loss in
the coil remains unchanged, it will just warm the water (advantage : tea is
ready after each QRSS QSO) instead of the copper. So cooling is OK to
prevent destruction of the coil but will not give you any more ERP.

PS : maybe if you take into account that copper at 100°C has a higher
resistance than copper at 20°C you might gain a few micro-Watts.
