[hpsdr] ANAN-100D TX Spectrum

[f6bki at orange.fr]

Hello All, more on the spectrum issue with my brand new ANAN-100D:
After sending the first message I  Got few answer , thank you , but not from 
ANAN-100D users .

I have connected my Spectrum analyser to the XVTR Output and on 6m there are 
also Spurs , it means that probably the PA is not the cause of the problem.
If somebody wants to see the spurs on the spectrum analyser I can send them 
a picture .

My feeling is that the spurs are generated on the Angelia board.
Please if you own an ANAN-100D take a moment and look at the TX output 
spectrum on 6M  , I would like to know if I am the only one with this issue.

I hope the Apaches Labs people are also reading the list .

THANK YOU

Hello all , today I have  checked the RF Spectrum on transmit of my new
ANAN-100D.
On 6m there are plenty of spurious about 50 dB below the carrier from 50MHz
down to few MHz .
The ratio Spurious/Carrier  is almost independant of the power level, in
comparaison an IC7000 is at least 20 dB better around the carrier and much
better away from the carrier. .
On the other bands the spurious are about -60 dB below the carrier .
Looks very high !!!! No way to drive an amplifier with such a signal!!!
Mesurements have been made on a 50 Ohms load on an  ADVANTEST Analyseur .

As anybody checked his ANAN-100D ??
