SOLF: Software and Filter Corrections

Yesterday came the long awaited update of the SOLF. No problem. We will see what can be done.

While listening on the band I was disturbed, that the 500 Hz filter was someway totally out of reach so I plugged in the noise generator and fixed this problem roughly.


So it looks better. You have to read it from the bottom.




  • CW LP - 2700 Hz
  • CW LP - 500 Hz 
  • CW BP - 2700 Hz 
  • CW BP - 500 Hz 
This can be still improved, but I wait until the final alignment. I hope that there is an instruction how to do it properly.

Please look at the Update. My alignment looks right but is somewhat wrong.


Stay Tuned!
