Hi All

 

Oscar, LU1DOW sent me some pictures and details of his station which would like to share. You can fin them in this Dropbox link

He is picking the signal from IC756 PRO exciter stage at low level at 13.700 MHz. The signal is amplified and divided by 100 to get

the 137KHz and feed to a driver stage. Then a ceramic Tetrode 4CX1500A with 4KV voltage produces an antenna current of 8,6A at 1400 W

The antenna is an inverted L, 18m vertical and 20mx3wires horizontal. There is an additional loading coil at the top of the vertical section

 

It’s being a hot summer in Buenos Aires. Not a good weather to work outside at the tower. Oscar is waiting for some shadow to

let him fine tune the aerial and go for Tx. Hope it will be soon
