The Pawnee Radar was visited this past week

The radar was being checked to see if it needed to be calibrated

A test will begin there sometime in November

This shows the dish inside the Radome

Here are the synchros that transmit the azimuth and elevation rotation of the dish

This is where the ARS-20 encoders will go

The synchros are needed to be replace because they are very old and can’t replace parts

Lots of wires over long distances are expensive and they are prone to noise and damage

Digital outputs from encoders compared to analog from synchros

Note: Lots of wires

Finally, was able to implement simple logic devices such as ands and ors

Determine output from encoder and how it relates to interface board

Working on converting Gray code to Binary code, then will try simulations

Upcoming developments processes◦ Parallel to serial converter, convert Serial

Synchronous Interface (SSI) data
