Leave it to a newbie to ask this kind of question.:blink:
You'll always need the "physical" part of the swr meter actually in-line measuring the swr. No way around that. Then you would need an interface and software to display the results on a PC. Linky below to a unit that does this.
Wavenode SWR and RF wattmeter with computer graphics and DC power monitoring. Complete with SWR protection and high power remote sensor. Also includes audio and voice announcement of RF power and SWR.
I would think there could be some significant cost saving in a sensor/software combination by eliminating the physical meters, controls and some circuitry that could be handled by software.
But I suppose the least cost is in the physical hardware. The most cost is for recouping the design, tooling, assembly, marketing, and distribution cost. Even if fully "virtual", the marketing and distribution costs are still significant.
