That seems to answer my question - not a problem.

I get interference from a hub in the basement near the rig. Most noise
is on 20 meters. The problem is especially bad if there is an
unterminated wire connected to the hub.

Las Vegas NV, since the MGM fire, requires all data cable (cat 5 and cat5e
included) to be run in Metallic conduit... I built a warehouse for a major
parcel carrier (who likes to destroy boatanchors ) What an expensive city
to run data cable (and phone)!!!!!!!

Yes sir,

In the early days of networking, I had to install and support a WIDE variety
of networks and
physical media (and a few different file server OS - but largely Novell !!)

In addition to the original Token Ring 4 Mbps and Thick and Thin Ethernet
(10-Base-5 and 10-Base-2)
Altos Server and original 3com Net (Thinnet based)
Novell's S-Net
Proteon's 4-Net and 10-Net (10 Mbps 10-Net was not adopted - later IBM 16
Mbps was)
G-Net ( 1 Mbps)
Omninet (for Apple II)
ARCnet Token-passing (PC and old Datapoint 8-bit processor version)
Sytek / IBM PC Network (used 75 ohm CATV cabling)
Appletalk for Macs
AT&T StarNet (another 1 Mbps)

and others from Novell lab classes when Ray Noorda showed up and signed your
certificate!

Today, the company I work for is owned by the US patent holder for Token
Ring

.... who said the world is small?
