Rummikub tiles can be used for more than just playing games.

In Swaziland we do not get the day off for the U.S. Independence Day, so it was work as usual.

Today Graham and I continued our research into the filament issues of the transmitters that are causing intermittent problems.  This has involved using a digital oscilloscope to monitor currents and voltages of the filaments with the hope of ‘catching’ and recording these reading when a fault occurs.  We have had some success and need to analyze the results.  Hopefully, it will be possible to eliminate the problems.

I do want to stress that air time is not lost due to these problems, as they only occur when the transmitter is coming up.  Curing the problems, though, will make the operators’ work less stressful and increase the life of the transmitter tubes, which cost over $17,000 each new.
