Re: [IRCA] Antenna switches for automated spectrum recording



I've used a USB controlled relay board to switch two antennas to one SDR remotely, Mark:

(this outfit has a lot of neat toys)

However, if you wanted timed switching, you'd need to write your own routine (perhaps) I didn't look too far, as I had an immediate problem that needed solving, controlling a remote receiver/computer via Remote Desktop (Teamviewer is probably an easier alternative), and switching antennas at a remote site. But, I was the "timer" as far as running the receiver and switching the antennas.

But, it should be doable, and could be done.   Not by me however; sorry.

best wishes,

Nick

Given the following criteria:

1. Two or more antennas
2. Spectrum recordings are set up for two or more times of the day (sunrise and sunset, for example)

Are there antenna switches out there that can be switched programmatically from my PC at certain times of the day?

The goal is to be able to program spectrum IQ (or even single frequency IQ or audio) recordings at time T using antenna X.

Or at the least, the goal would be to be able to remote in to my PC and run a program that would allow me to (a) select which antenna is active, and then (b) start a recording. I can already do (b), but the recording will be using whatever antenna happens to be selected on the mechanical switch (and it's usually the wrong one).
