Hi Ivan!

23 Feb 2021 02:35, from Ivan Mikhalev -> All:

 IM> I have finally tested the HackRF for spurious emissions, and I can say
 IM> it is definitely acceptable.

 IM> With SDRAngel acting as the IQ modulator, I got really clean
 IM> performance on 40m. There is a DC spur at IF center though, so offset
 IM> tuning should be used.

 IM> Wideband spur emissions are minimal, shouldn't interfere with anybody
 IM> on HF. Yet to get reception reports though, as now I have no license
 IM> and no suitable power PA.

Thanx for the info!

CU, Ricsi
