[hpsdr] Noise floor increased

[Georg Prinz]

Hi Tony,

did you check the ground-pin of the BNC-connector? I changed several 
connectors, already. If
you connect heavy coax-cable these pins break or get loose. Nowadays, I 
am using a thin flexible
coax-cable to conect hpsdr boards with the heavy coax cables.

73, Georg
