[hpsdr] Fwd: Hermes Ethernet

[Henry Vredegoor]

Hi Bob, All,

I am experiencing the same and I must admit that it is all cheap 
hardware and cabling that I'm currently using and no special attention 
was given to the routing layout etc. because it is all for temporary use.

But I think to minimize interference the same old rules apply like for 
any data cabling scheme:

Use of good quality  cables and connecting hardware
Use of good quality network gear, preferably in metal enclosures / cabinets
Good earthing scheme
Good routing schemes for cabling, (metal shielding cable ducts?) away 
from antenna (receiving-) cabling
Good power cabling

  I think if you search the net you will find good information on the 
subject.
But it also can be hard to fix/find an interference problem introduced 
by "wrong" wiring.

73's,

Henry.
