I just extend the wiring from the radio to the fob/URI. I use 8 cond. 18AWG shielded cable. My cables are ~20 feet long to get from a wall rack to the radio rack. Jon On 12/4/2011 11:04 PM, Scott Weis wrote:
The spec for USB is 16 feet max. I have used a USB to cat 5 extender and extended over 100 feet and the URI worked fine.

wondering...there's a legitimate length restriction on USB cables...but, from the dongle to the radio...the audio and control signals...analog...
Reason for asking...have my asterisk computer in the spare basement room here...right next to the radios. All the nice dongles blinking in unison..but...thinking (I know...dangerous) it would be nicer to actually have the computer in the same room as the rest of the shack, and the radios out in the other room so the fans on the power supply don't intrude, etc. And be able to sit at my work area, rather than standing in front of the rack...when I'm hacking at the configuration files, or...???
so...thoughts about how long the cables from the dongle to the radio itself could be before running into trouble?
Not thinking of using JK (the old Bell 2-pair station wire, believe it or not, have a couple boxes left from the 80s...:)) or UTP...but, have a nice spool of belden 8451 (2 stranded conductor, shielded) that's used almost as a given in most commercial radio stations etc and we never had a problem with l-r phase shift or degradation (and this was running audio signals in a transmitter room with 25KW boxes and STLs, and the like floating around...). *shouldn't be a problem, right?*
Just thinking out loud...I know, try it and see.
