[Today’s run: rest day]
I made a bit more progress on the GPS-DO. I now have the first chain of the power supply working.
The power switch works. The rectifier and filter capacitor are doing the job. I have 24 volts going to the crystal oven. I used the ripple calculations in EMRFD and the ripple was about 10% until the oven gets warmed up and drops the current. Then things flatten out nicely.
I have a bunch of boards to mount in my chassis. And I have to wire the various parts together. This is always a difficult step in any project I tackle. I don’t have a large collection of connectors so I end up using a lot of point-to-point wiring and it usually looks nasty. I’m thinking about putting in a couple of terminal strips for the various voltage levels.
But I haven’t broken anything yet, that I know of. So keep moving forward.
Today I also reviewed the ARRL VE information. I’m supposed to help at a test on Saturday. I signed up as a VE long ago and have never used my certification. So I figured I had better do a review.
