[hpsdr] PennyWhistle MOSFET's

[Riho B., ES7AAZ]

Bemnet,

there is nothing wrong with DSP, there was something wrong with audio
levels (+10dB). Deleting the database resolved the issue. DSP output looks
smooth and OK now.

P.S. Helmut, yes, Penelope shows very good parameters in two tone test. I
see 3rd order products 65dB below the test tone.
