Fiber on the Pole
The loop will give them slack to create my drop.
As you recall fiber to the house has already been pulled.

Punched or Drilled
The bulkhead plates are done and ready to be mounted on the wall. May get that done this weekend.

Fiber at Boxwood Pole
Fiber coiled and ready to be connected to overhead when it arrives. Current expectation is 2-4 weeks.
Sequence to Boot the Mountain
Remote and base station computer are never turned off. To operate each morning :
- On remote computer (where the operator is sitting)
- start Teamviewer to enable connection to base station (where the radio is located)
- start Skype.Remote to create audio path to the radio
- Using Teamviewer on remote computer
- connect to base station computer
- start Skype.Primary on base station
- From the remote computer, call Skype.Primary from Skype.Remote
- Control program FT2K will power-on all equipment at the base station
- FT-2000
- DTS-4 antenna switch
- LDG Antenna Tuner
- If I'm going to use HRD or other control program
- Power base station equipment using
- Browser interface to IP switch
- Stand-along power switch program
- Start the control program
- FT2K
- HRD
- FT-2000RC
- TRX-Manager
- On the Air! Wasn't that easy!!

W8JI Revisited
Regarding a multi-band dipole...what is the best balun for maximum efficiencies across all HF bands?
The best balun ratio for a dipole depends on a combination of factors, including frequency, feed line length and characteristic impedance, antenna length, and height above ground.
If I really wanted to get the best results using a balun, and I had a particular balun in place, I would examine the impedances across the bands of interest on the coax side of the balun. If I had high impedances and was using a 1:1, I would try a 4:1 balun, and vice versa.....or change the feed line/antenna length.
You may remember I did the latter when designing the 202/60 antenna. Note that Antennas less than 80% of a half wave can have low impedances, so caution is needed on short antennas.
In the past I have tried 4:1 and 1:1 baluns. At the moment, I am using a 1:1, but I am mostly just on 80m. I am able to tune all bands with my auto tuner, but that does not mean it is efficient on all bands. This antenna was really designed for 160, 80, and 40, and sort of for 60m.
If you are really serious about this, You could go with an elegant approach and use a balanced tuner, such as the Johnson matchbox. It does not require a balun. The addition of one outboard capacitor makes the Johnson boxes usable on 80-10m, including WARC bands.
Further, my tests show that the optimum length for "W8JI" for 160m and up is somewhere between 202' and 208', not 220'; and that is also using 300 or 450 ohm ladder line, 60' long, with a 1:1 current balun, antenna at 55' height.

Almost done...
New power strip provides enough outlets for all modules. Wireless router raised slightly and now provides improved signal. Final step is to prepare all the jumpers from distribution module to switches.
