For who's interested and wants a to reduce selfmade QRM to a minimum:
I've decided to connect my Remoterig with a fiber-optic link to the router.
This gives galvanic seperation and keeps ethernet/router QRM at minimum levels.
With fiber optics you can cover a 2km link between router/DSL and your Remoterig.
The Allied Telesyn "media converters" are a good solution for this as they are becoming very cheap secondhand.
I tried the MC101XL (100baseT) with good results, but still noticed some ethernet carriers.
Now I use the older AT-MC13 (10baseT) which I obtained for 20 euro a piece on Ebay.
QRM from the ethernet link and Remoterig data noise has been reduced drastically.
If you want to locate your station galvanically seperated in a minimum QRM location far away from router/ethernet noise I can highly recommend a fiber-optic link.
