Virginia went to work with us today to remove the SW100 parts, that were packed with the transmitters, from inventory lists.

Since the spare integrated circuits have arrived that were ordered last week, Larry spent time installing IC sockets and five new ICs on the Tompson A to D card that he was working on last week.  Unfortunately, the problem was still not resolved.  We then tested the remaining socketed ICs on a working board and found no problems with these.  Once again, we’ll have to investigate further later.

Larry began to help with connecting the high voltage transmission line connection to the antenna switches.  We started with the easy and short runs first.

Joel and Jim are checking out the ‘fit’ of the first of several short connections

Detail photo of how the connection is made. The diameter of the pipe and the spacing between the two pipes is critical for maintaining the 300 ohm impedance of the transmission line.

After verifying the first connection, Joel, Paul and Jim start to connect more switches.

The short connections are completed on the first five switches. Note that the fifth switch at the left needs to be out of line with the rest, which requires slightly different connecting pipes.

This evening, we got water refilled at the Water Store.  This time we had two 5-gallon jugs that could filled.  We actually found a third jug hiding in the bottom of the kitchen cupboard in a hidden corner.  This will help greatly in reducing the number of trips for purified water refills.
