[hpsdr] ANAN 10 28Mhz tx spectrum and generated birdie

[Dominique Dehays]

Hi Helmut ,


I can assure U I know very well how to use a spectrum analyser and I 
garantee there is no saturation in my measurement. Those spuriis really 
are there and there are some out of the ham bands as well. The question 
now is :

are they coming from the sdr board , or from the amplifier ( maybe it is 
time to look for some DC-DC converter inside or something like this?)
