<azonenberg> Every time i get better characterization data it's just so eye opening
<azonenberg> i'm now questioning a lot of things about the PT5 PCB that i wasn't before
<azonenberg> Like the SMPM connector launch
<azonenberg> i'm realizing that 8.5 GHz dip i had before is perfectly sized to be a reflection off the SMPM
<azonenberg> So i'm gonna make a test fixture to measure it

<d1b2> <Code and Solder> I'm wondering if it would be feasible to iterate on this in real time using some conductive ink
<d1b2> <Darius> or copper foil maybe

<d1b2> <azonenberg> No. It's not the same thickness as the copper
<d1b2> <azonenberg> i've tried some tweaking by using a scalpel to shave traces down to slightly bring the impedance up
<d1b2> <azonenberg> but getting consistent results (within 10-20 μm) is really difficult freehand
