It has not been as cold in the mornings with temperatures around mid 50F the past couple of mornings.

Today the problem with the ‘ground switch down’ indicator not functioning on TX3 was addressed.  Graham removed the grounding switch assembly and it was discovered that the ‘cam’ that is supposed to operate the ‘down’ limit switch was jamming on the end of the limit switch lever.  We checked the other two transmitters and found that each one had this switch mounted differently.  The one in TX2 was mounted upside down compared to TX3.  This reversal virtually eliminates any possibility of it jamming, so it was decided to remount TX3’s limit switch in this configuration.  It did require carefully marking out and drilling two new mounting holes.  It was mounted back into the transmitter and now works great.

This afternoon, another intern, Samuel, from Canada arrived via the bus from the Johannesburg airport.  Did not meet him yet, but hope to see him tomorrow.

This evening, Virginia and I were invited over to Steve and Lorraine’s for desert.  They had also invited Jonathan, whose 23rd birthday is today.  We had cake and tea, then played a few rounds of Mexican Train dominoes.

When we got back to our house, I forgot to remotely switch off the alarm.  The alarmed sounded for a few seconds, but I managed to get it switched off before it started alerting anyone via cell phone text messages!
