Hi Luis,

Time to connect a MOSFET to the MOSFET-driver!

73, Stefan

PS: Don't forget the LPF :-)

Hi Stefan

 

The FFT lenght is 32768 and the exported FFT bins are 16384. Anyway the .usr file is attached

 

The  signal is almost 20dB over noise at 5mHz bandwidth. Clearly visible and I can also see the sidebands in other (faster) instance

when modulating phase at 0.1 s rate. The power is very small. Just what I can get from a MIC4452 mosfet driver at 12V and

the Tx antenna is just a 5cm piece of wire. The Rx antenna at about 15m away in the roof

 

Transmitting from my QTH with the big antenna and same power produces a similar S/N

But then we add the posibility of a timing offset to the puzzle L

 

73 de Luis
