New Year & New Wiring Configuration


With a new year comes a new purchase and a re-wire of the shack. 

The new purchase is an LDG AT-200ProII antenna tuner. Some nice features of this unit include two antenna inputs and a 200-watt max power handling with SSB and CW signals on most bands. Another great feature is the versatility of this model line from LDG allowing them to work with almost any transceiver instead of some of their other models that are designed to pair with a specific model of transceiver (for example my Yaesu FT-847 transceiver and it's matching LDG YT-847 auto tuner).

The new wiring layout suits my operating style, one operator using one radio at a time. It will allow me to have up to 4 of my HF transceivers wired into a grounded antenna switch. I can select one radio at a time to operate on. Typically the other radios are turned off when not in use.

After deciding the radio to operate with, and switching to that radio on the switch, my signal will pass onto a nice large display HF SWR Meter (Daiwa - CN-801HP) before passing into the new auto tuner (LDG AT-200ProII). In the tuner, I can select either one of my HF antennas (dipole or beam) to transmit & receive on. Each antenna has a high-quality lightning arrestor installed and proper grounding of all the equipment and antennas (safety ground, lightning ground, & rf ground).

I know this isn't rocket science and I'm not inventing something new here. For my solo operating style this is just a new versatile configuration that supports all of the following;

  • Four (4) transceivers wired in and available for use (always just one at a time).
  • A manual switch that also supports a straight to ground position when no equipment is being used.
  • An investment in a nice big & well lit SWR Meter that works with any radio selected in the configuration.
  • An investment in a nice Auto Tuner that works with any radio selected in the configuration.
  • Two HF antenna choices that can be easily selected on the Auto Tuner.
