[hpsdr] Spurs!!!!! Hermes! !!!!

[Helmut Oeller]

Hi guys,
 
I rechecked my (calibrated) Hermes , directly terminated at the SMA socket
and after disabling dither which is usually enabled in my case.  I can
detect @ B=500 Hz, Bin width 1,465 Hz, ATT=0:
24,556 MHz  -87 dBm
36.88    - no detect
49.1  -131 dBm
49,9  -126 dBm
52.5  -127 dBm
I didn’t discover the last 3 freq due to dither before, sorry.
But anyway it seems there are significant differences between the boards.
BTW I using an early board from Abhi and I’m not unhappy with my current
results. I observed an improvement of more than 15 dB compared with my Atlas
based system.
