Vevtor Wattmeter Sharing Device

I am working on a 4 port antenna selection device that works with SmartSDR using a Flex Smart USB cable and automatically switches your LP100A/500/700,PowerMaster or any other high end SWR bridge/vector analyzer betweenn any one of up to 4 antenna ports on your HF Amplifier.  This allows you to make use of the high end analyzer without having to manually switch antenna cables.  It takes bcd instructions from the Flex and places the analyzer into the correct antenna path.  I am curious to see what the interest level is.  I am deploying it at my station now.  It supports full legal power.  Let me know if there is interest.  It will be priced reasonably.

    To all those interested.  This is intended to be a simple to use device and relatively inexpensive compared to the alternatives.  Please email me the number of feedlines you would need to use for your wattmeter and the bands used on each feedline. (Keep in mind that I am focused primarily on 160-6m to keep the number of ports to something manageable while looking to support as many different applications as possible.  My goal is to do this with only  a small 12VDC source and one usb cable to the rear of the Flex.  No Cat, no Ethernet.... all configured from within the SmartSDR as it exists today. (At least that is my goal)  Please email to ed@w2ph.com

    If you are using an LP-500 or LP-700, they have four (4) inputs for up to four power/SWR couplers and can be set to auto-switch to the coupler that is active.  Of course, you need to purchase the additional couplers, but they can then be optimally placed wherever needed in the shack using CAT6 cable from the couplers to the LP-500/700.

    Yes, Bob, it will work on a Flex barefoot or with any amp.

    Mark, It should work in the application you describe.  At this time we are not looking at anything network based.
