<div dir="ltr"><div>Hi John - some things to consider about the USB extender cable:</div><div><br></div><div>1. How will the RX888 be powered when using this cable?</div><div>2. In the one review - the extender was being used to bring back data from an HDMI switch to a computer.</div><div>HDMI switches are usually powered from the HDMI cables or via a local DC input, thus not needing power from the USB port.</div><div>3. I'm guessing much of the hash is due to the DC USB power from the computer radiating as RFI on the cable</div><div>when the shield is making poor or no contact. <br></div><div><br></div><div>-- Tom, N5EG</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 27, 2024 at 8:26 AM John Ackermann N8UR via TangerineSDR <<a href="mailto:tangerinesdr@lists.tapr.org">tangerinesdr@lists.tapr.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I had the idea last night that we could put an RX888 and GPSDO at the <br>
base of our active antenna and run an optical USB3 cable back to the <br>
host computer. That would move the radio far away from all the computers <br>
and other noise in the shack. The only copper connection would be for <br>
power, and we could filter the hell out of that.<br>
<br>
Something like this:<br>

<br>
might do the trick. (Note -- I don't know if 5gbps is sufficient for the <br>
RX888, but if not there are 10 and 10 gb cables available for more money.)<br>
<br>
A challenge is powering the transceiver at the far end, but that <br>
shouldn't be too hard to do.<br>
<br>
Has anyone considered this?<br>
