Re: [IRCA] Antenna switches for automated spectrum recording

[Nick Hall-Patch <nhp@xxxxxxxx>]

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
