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
https://www.dropbox.com/sh/6kr0993et5r215s/AAAuQbq7R1iDKVAMF0oV3BIja?dl=0
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
