im planning on using a RPI 4b to send a stream to a TX. i want to add a touch screen to the RPI and use it to turn the power on and off to the TX via the a solid state relay. The screen will be mounted on the front of the box to provide information on what is playing. just waiting on a few more bits to turn up to test this all out.

question. how would i go about getting the RF power and SWR to be displayed on the front?
