not the one I was looking for, but has some of the data (replacing the router) https://www.youtube.com/watch?v=vrGCL9pNDDc Here is the one I was looking for (modifies the router) David Lang On Thu, 16 Feb 2023, David Lang via Starlink wrote: > Date: Thu, 16 Feb 2023 15:23:33 -0800 (PST) > From: David Lang via Starlink > Reply-To: David Lang > To: Ulrich Speidel > Cc: "starlink@lists.bufferbloat.net" > Subject: Re: [Starlink] Starlink power use & satellite tracking > > I've also seen people shorten the dishy cord and replace the inverter and > internal power supply with a 12v -> 48v converted and had the dish power draw > drop significantly.
