Beautiful Fall day in the Sun and calm air.  A bit chilly at 9:30am but 
wormed up at day went on.

Fixed three things:

Second 7-element 6m yagis now works; combined gain is 15.75 dBi (free 
space).  Ground gain possible up to 20 dBi.

Just in time to work FO/W7GJ on Rimatara Island and TM7MB on Hiva Oa 
Island in French Polynesia (W7GJ 6m-eme Dxpedition).

Also got PL259 connector installed on second 2m KLM-11 yagi but still 
bad SWR* so didn't Install the 2-way splitter. but used a single LMR-400 
cable previously used for 6m for single jumper to the LMR-600 tower 
line. *LMR-400 cable showing aluminum oxydation/contamination, so cable 
will have to be replaced (not enough time, today)

Using 147.300 repeater for test, single yagi produces S8/S9 return 
signal where vertical shows S7.5.  Approx 10-dB improvement.  Antenna at 
45-feet.

Also found bent director on 432-18 yagi touching driven element; 
straightened and now SWR is 1.2 432-446.  Still need to complete cabling 
of the remote 100w PA and Preamp, before full use is possible.
