New antenna tuner box

Finally a new box for the antenna tuner, I really hope it's final, it's already the second incarnation of this tuner....

 A good friend offered his carpenter services to build a really nice box without screws to hold the front and back panel.
And I could not say no, I could never had build something like this, it's out of my patience limits, not to mention carpenter skills...

Inside is also the swr meter circuit board:


 The tuner it self it's not connected yet since I needed to calibrate the swr meter part first.

Will be using 2 scales selected by the switch bellow the crossed needle meter. One 0-30W and the other 0-300W, just hope the rectifier diodes can withstand the power.

Matching the "Speaky" line?



Maybe I can get some more time this week to connect the tuner parts, coil and variable caps for a live test.

Have a nice week.

Wow, it looks nice Ricardo. Hope to work you some time with that Speaky radio of yours. If you're finished we should make a sked sometime. 73, Bas

Hello Bas,

Thank you for the nice words. Let's hope the tuner works nice and then we will make a sked, for now only 40 or 17m :)
