Ergonomic Layout

I have just enough space to rackmount everything. Considering I also have rear rack rails, some less important items can be mounted from the rear. This is all about the ergonomic layout. I may even build some breakout panels for the antenna and audio connectors. I’ll be using a combination of 2U and 3U rack shelves (special thanks to the folks at Gator Rackworks!)  I had to go 3U for some shelves in order to get a useable depth. Most of the radio gear will sit on shelves.

The current layout plan (from top to bottom):

  • ROTOR SHELF       4U
  • AT-AUTO HI           4U
  • AT-AUTO LO           4U
  • 2M RADIO / TNC   1U
  • FLEX VU5K            6U
  • 1K-FA                      4U
  • FLEX 6300             2U
  • FLEX 6700             2U
  • AC POWER             1U
  • PC#1 W7                4U  <<< DESKTOP
  • PC#2 W10              4U
  • PC#3 SERVER        4U
  • ASTRON RS-70      4U

I need the radios and amplifier close to the desktop, placing other ‘less touched’ items either down below or up above. I think the ergonomics are OK at this point.

Before I can start building I have to empty the shack so I can remove all the dust. I have a significant dust problem. And the problem was most apparent as I swapped out the cases on the two production PC’s. Choking on dust.

The plan is to empty the room, and mitigate the dust. I plan to use an air compressor to blow off the dust that’s embedded in the stucco-like ceiling, then, I’ll thoroughly vacuum before having the carpet steam cleaned. Going forward I will employ an oversized HEPA filter in the radio room which will run 24/7 to capture all particulates and hopefully eliminate or at least vastly improve my dust problem.

PC Monitors In Place – 021718

The PC monitors are in place, look great, and exhibit no RFI at full output. The operating position is fully tested and ready for the contest.

I decided to try a 4K UHD monitor and selected the LG 32UD59-B (top) and it looks fantastic!

PC Monitors: View from the operators chair!

PC Monitors: Everything within reach and easy for me to see.
Everything within reach and easy for me to see.

The few minor problems that remain will be addressed after the contest. For all intents and purposes, this project is complete. I may decide to upgrade the PC monitors in the near future, but for now the station hardware is complete.

Now it’s time to OPERATE!

-P.S. 02-23-18:  I was doing some testing with the data cable connected to the recently installed AT-AUTO, and the tuner works as expected. I was able to work KB3RHR and K7KPH and both gave me great reports.

AT-AUTO Arrived and Installed – 022018

The AT-AUTO arrived safe and sound in spite of a loose packing job. By the time the box arrived it was all “rounded out”. This is what happens when you use a light gauge box for a heavy item, and the item is ‘loose’ inside. Yep, you guessed it…the box was full of styrofoam ‘peanuts’. Hey, it was a happy ending, the tuner works as expected so far. There are a couple of cosmetic differences that I imagine have to do with the different production runs. Overall I am happy with this purchase. More info available at the Kessler Engineering website.

AT-AUTO Data Cable

The data cable was scheduled to arrive today, but did not. So I say ‘so far’ because I could not test the data port tonight, but I’m sure it won’t be a problem. The coax cables arrived on time because the eBay seller shipped them on Saturday! Hat’s off to “WifiExpert” on ebay! Highly recommended!

AT-AUTO tuners provide near perfect matches
Palstar AT-AUTO – The perfect tuning solution for my shack!

The AT-AUTO was one of the last pieces I needed to complete my 2018 station overhaul. I now have near perfect SWR everywhere. The Expert 1K-FA is a great amp, but the internal tuner only matches up to 3:1 SWR. I had issues with antennas being out of range of the 1K-FA internal tuner, and resolved ALL issues via the AT-AUTO.

Fully Automatic Tuning – QRO

I cleared the memory and trained the tuner on all bands, then did the same with the tuner in the amp. The result is a perfect match on any frequency, on any antenna, and tuning is fully automatic! I’m very happy to have this in place for the ARRL contest.

The AT-AUTO ‘s will follow the active TX slice on the radio, and enable the operator to concentrate on the work, and not be concerned with making errors when changing bands etc.
