Very explanatory! I was just looking for such tutorial to properly do the job with W1GHZ 10 GHz transverter and the related LO multiplier! A very very detailed video!! Tnx de Alberto, IZ2EWV
Hi Alberto. I am glad you found this video helpful. I suppose there are a few different ways to do it, but this method works for me. Good luck with your project!
You don't really want lock washers on jam nuts. If tightened correctly, jam nuts don't work loose. A washer between them actually makes it more likely they'll come loose.
Thanks for the comment. I know it is unusual to use washers with jam nuts but I lack the skill to do it without them. The tuning is extremely touchy on the 10 GHz filters. Without the washer, the transition from jam nut putting no tension on the tuning screw and full tension happens in a very small fraction of a turn of the nut. This makes it very difficult for me to keep the filter peaked while tightening the nut. The split washer smooths out the transition, applying tension to the screw more slowly, allowing for it to be more easily re-adjusted as the jam nut is slowly tightened. I wonder if a modification to use a tuning screw with finer thread and/or a thicker nut soldered to the pipe cap would help with this. I will check to see if alternate hardware is available before my next project using pipe cap filters.
Of course. But when you are on a small budget you make choices about how to best use available resources. Now that I learned how to do this with the tools I have, next time it will be much easier and take less time. The money I didn't spend on tools can go on parts for interesting projects.

Wonderful! I will have to install several caps soon. Some great ideas. Thanks.
I have been away from YT for a while. I hope your project went smoothly.
Very Innovative though techniques yuo use on doing certain things
Thanks. I have a lot of experience figuring out how to do things with what is available.

You pay for what you got that saying also goes for the tools you buy🎉 and supplies you use
