S52AB/B
WITH A
QUARTER WAT (270 mW)
on 3578.8
kHz
in
normal CW
by S52ST (measurement and calculation
power), S52AS (measurement antenna and finalization of the device)
S52AB
(soldering and realisation). So, each contributing its share ... hi
Period from 21.Januar to 29.Januar 2015
Test transmitting location on JN75ou - S52AB
TX:
signal sourse is Crystal Oscillator "cube" 3578.8 kHz (14 mW)
and QRPP QRO with 2N2369
Keyer:
Arduino Uno, speed 13 WPM
Antenna: Inverted "U",
7m. up, 40m. long. Tunning with L-Network. Antenna current cca 52 mA RF
Except active
part of the antenna, is dedicated attention for the second part of the
antenna (effect metal structures in the area and trees
around the antenna) and
radials, of course. Obviously successful.
Calculation of power (S52ST) and antenna measure (S52AS)
