Today started off cloudy and cool with possible rain in the forecast.

Tobi needed to go to the electrical supply shop to pick up electrical cables for installing the remaining two air-conditioning units, so I went along.  It was interesting to see what was on display.  There was an ample supply of swimming pool equipment and a lot of high-intensity LED security lights rated up to 500 watts.  There was one solar powered kit with a 200 watts rating for up to 12 hours service and a remote control unit. After looking at the included battery rating of 18 amp hour at 3.6 volts, we quickly came to the conclusion that the 200 watt rating was actually an equivalent light output compared to a 200 watt incandescent bulb.  Also that the 12 hours was for a reduced lighting setting of 25% (out of a selection of 25%, 50%, 75% or 100%).  The price of $70 for the complete kit seemed to be quite reasonable.

Finally emailed the MW feedline parts drawings to Mike Sabin and other TWR engineers and started updating the hand-made feedline frame drawing made in 1980.

Tobi mentioned that the regulator for HC100-7 sometimes ‘hunts’ (oscillates) between two settings, which is a sign that the sensitivity may be set too high.  I found a manual for it online, and stored a copy of it with the HC100 documents.  We removed the cover of the regulator and adjusted the sensitivity CCW by ¼ turn per the instruction manual.  Hopefully that will take care of the ‘hunting’ issues.

When we left the transmitter site this afternoon rain was pouring down and it was noticeably cooler.  The Toyota Rav 4 indicated an outside temperature of 9C (48).  Though there was water in places on the dirt road, there were no muddy sections.  The gravel seems to be holding up well.

Virginia had a nice fire going in the fireplace when I arrived home.  After supper, there was a really nice sunset and we invited the Stavs to bring a game to our warmer house.  They brought their domino set for Mexican Train and we had a cozy game night by the fire.
