Re: [Elecraft] W-2 Cable Length
I am running 4 foot Cat6 cables, for my W2 watt meters, and am having no issues. 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.

[Elecraft] W-2 Cable Length
Good Day. Does the length of the data cable between the W-2 meter and its sensor matter? I would like to use substantially shorter cable than came with the kit. Thanks.
