Tuesday 23 August – Transmitter Testing

This morning, I again saw warthogs on the way to the transmitter site.

Last night, the transmitter that was repaired had several PA Plate Peak Voltage trips. We spent a while this morning doing test broadcasts. None of the tests using the same frequency, antenna and power level produced the same trips. The trip level was set at 33,000 volts and with high level programming during the tests we observed only 29,000 volt peaks. We set the trip level to 35,000 volts and requested that the operator observe the peaks during this evening’s broadcast for anything higher than 29,000 volts.

In front of the transmitter building is a ‘sausage’ tree. Until last week it had no leaves with ‘sausages’ hanging from it bare branches. Then almost overnight it was full of green leaves.

The largest ‘sausage’ fruit on this tree is about 18″ long.

For the past couple of days, I have been working on feedline drawings in my spare time. Today was trying to draw the insulator that is used for the feedline.

The older insulator on the right is like the ones used in the MW feed line here. None have failed in 40+ years of use. The one on the left is a newer version and can be used as a direct replacement, if needed.

While driving through Dombeya Game Reserve this evening I was finally able to get a photo of some wildebeest (gnu):

Two wildebeest–only when posting this photo did I notice there are at least two more in the bush!
