Re: SDR's and ESD Damage.
If you have a transmitter involved this system will "work" but it is not optimum. Ideally the TR switching should have a aafe sequencing, which may clip off the first syllable of a word when using VOX.toggle quoted messageShow quoted text
First the antenna "relays" must switch to the safe TX position, and then the transmitter power amplifier can become enabled.
Disable the transmitter PA and then switch the antenna "relays" to the RX position.
Alas, without modifications to most transceivers won't work. The can be made to work with an external TX switch that handles VOX for SSB folks (perhaps with a couple syllable audio dealay).
The last I looked at it the Signalink line was missing two critical features. It needs to feed out an antenna switch interface control and a separately timed transceiver control. It also needs a computer controlled TR switch signal for very fast switching signals such as ALE. (Using VOX trims off enough of the first transmission that one of three redundant signals is missed reducing performance under poor conditions.)
