From 1943 ~ How a vacuum tube works. More Progress.

An interesting You Tube video from 80 years ago on: How a Vacuum Tube Works. It's short but lays out the fundamentals of operation of a Triode Vacuum Tube. Cool Beans.

Test Panel Cut Out

More fundamental work yesterday and I made a trial run cut of the two large rectangular panel cut outs and tweaked my CNC program a bit to account for a larger diameter end mill and this should result in a tighter fit of the ILI9341 Display and the 0 to 200Ma Meter. 

A Tight Fit is best described as the 21.43 Stone Mary Jo in the back seat of the 57 VW Beetle after consuming three Bob's Boy Hamburgers from his burger joint located near the Monroeville Miracle Mile Mall. 

Yes, Three of these delights!


Cleaned Up the ESP32 Digital LO/BFO Module

Mounted the Front Panel to the Plate

Front Panel Meter Cut Out

Installed the Color TFT, Meter & Encoder

Whew what a day for installations and finalizing a place for everything and everything in its place. Without a doubt vast experience and tribal knowledge accounted for today's progress. Things are coming together nicely. Lots of measuring before any cutting!

Today's work involves the drilling of the back panel. There are many installations to accommodate on the back panel including the Jones plug, the antenna connector, an auxiliary speaker output jack, ground terminal and external amplifier jack.  Many of the mounting holes duplicate those of the front panel and I will use the front panel as an overlay drilling template.

Them that know can make things go.
