[Skimmertalk] Switching antenna quickly between RIG + Skimmer to RIG only (RX to TX)

[Andreas Hofmann]

Thanks for the response.

Yes, my radio is a K2 with the receive antenna options installed.  However, I am not exactly sure how the setup would work.  Assume for a minute I had only a single antenna. I understand that I need a Y on receive. I still have the issue with switching on/before transmit.  How would RX antenna help here?

Thanks
Andreas

Hi Andy - Does your radio have RX antenna out and in jacks?  That plus a splitter is the absolutely safest approach to using your main antennas for skimming.  You could also use your radio's PTT out (used for controlling your amp) to switch the input of your Ensemble SDR to ground whenever you transmit, though I would be a little worried about timing in that case, for fear of getting RF across the relay before it finished switching.
