[hpsdr] predistortion

[Helmut, DC6NY]

Hi Mike,

yes, that's correct: 20 dB/div. The typical IM distance after
pred-distortion is approx. 60 dB in relation to one of the test tones (MIL
1131A-2204B) or around 66 dB relative to PEP (EIA standard). 

73, Helmut

Hi Helmut,

What's the reference level in your pre-distortion tests? Looks like -20 in
the pdf files?

Tnx,
Mike
