CNC2418 and TUX

TUX inspecting the led. Got a new switch box for the 12v LED and fan, along with some cable-chains and xyz stops.





What is TUX doing here? Apart from adding quality control, simple really the controller I rewrote with linux code so he is watching for bugs.. 

Tux had been in the shack hibernating amongst the bugs (spiders) but is now ready for more build projects.

EASY-100 PA options

The options for PA are multiple.

I have a couple of these which were said to not work too well but a mod was suggested and a couple in parallel 'should' be enough.




I also have an RF2126 which should be a bit better



and of course the EPAB






EASY-100

My Bodges.

Does it fit (trial)

The SMA are not always exactly straight :-) So GHz RF will have to go around corners.

 





The in and out will be via 2 N type chassis connectors I have used a couple RG316 pig tails for now.
 

The lid fits (yes the PA and the 2.4GHz LPF will go in another enclosure.
