Thread-topic: LF: EbNaut Attempt?

Thank you Riccardo

 

And thank you Antonio too, for the complete information in the web page

I will make a pcb with the 4013 and 4070 to be piggi backed into the 4013 shocket

Hi Luis, Markus, LF

 

Yes, Luis. Like Markus said, you're using a wrong position to change the phase.

With Tony IK1HGI, we have tested a solution to produce a correct BPSK modulation using a G0MRF PA schematic. Here's the link to Tony's website page, that explained clearly what to do:

 

 

 

In short, the XOR operation must be carried out after the x2 stage (D-ff, CD4013) simultaneously on Q and Q denied signals.

 

All the best

Hi Markus, EbNaut

 

It was me, with 80w from the D class PA

 

I'm producing 180° phase shifts with xor at 2x the frequency to feed the PA. So it seems that the PA do also reduce phase shifts to half :(

 

Which would be the way to do it ?

 

Congratulations for the EbNaut grabbers

Between 19:58 and 20:28 there was a strong and stable signal on 137490.0 Hz, coming in from west or southwest. However the keying seemed to be in 90° steps instead of 180°, so not decodable. Maybe a problem with a /2 divider in the transmit chain?

Best 73,
