Well the Hans Summers U3 Kit arrived and as you can see i had my work cut out....
As you can see the PCB's are really well made and a pleasure to solder
I mocked up a couple of test low pass filters to test the U3 with temp hot melt
Once the U3 was built i powered up and it worked first time
Filters in order from left to right 160, 80,40,30,20 and 10 meters with a fresh coat of transformer varnish which seals them from the elements and holds them in place... no nasty hotglue
The GPS i purchased from ebay and the lovely new case came so we are on the home straight !
