I suppose it could but that would make no sense because the receiver uses this high freq noise to operate its own squelch. You may want to play with the squelch setting a bit.

Could that mean that the discrminator could have a de-emphasys system right up front?

Some radios just don’t produce much HF noise, even right off the discriminator.  I have a Hamtronics xtal-controlled 220 receiver (R100) that does not make enough noise. The PLL version does. Not saying there is a cause and effect relation – the discriminator circuit probably has a lot to do with it.

Ok got it to tune. with rxboost=1. Did I forgot to reload the data when I made my initial test? dont know..

 

the program did told me that there was not a lot of high freq and not to use dsp.
