Hello everybody,
Thank you all for the reports here on the
reflector.
I am really glad to see my signal appearing so
well.
Equipement was as follows:
X-tal controlled oscillator + divider, and TX like
the design of G0MRF with an TC4426.
The final stage (class D) consists of 2 IRF 730
FET's from my junkbox.
Drainvoltage 32V (at key down), drain current
between 4 and 5.0 amp, so around 150Watt DC input at
maximum.
Antenna: 6m vertical wire, with 7m horizontal
topload (4 wires, spaced 50cm, in parallel) in my backgarden......
I'm planning to improve the TX and powrsupply a
bit, in such a way that the beacon should run at 200-250Watt DC
input
for hours and hours and
hours...........
Maybe I should go up a little bit in
frequency??
