Hi Roelof,

I just did a quick check on the remote Perseus at DL0AO
while resting on a couch in my shack.
This saved myself from having to get up from the couch at 36°C
for switching on my own Perseus. :-)
I see two 50Hz (+/-) spurs about 23dB down.
Noise sidebands are asymmetric "here".
On the lower side ca. 290Hz,on the upper side ca. 160Hz wide judging from
waterfall.
