Hi Joe,

With one receiver, one transmitter that would be pretty simple... if I fully trusted the T/R signal timing from the transmitter. Neither is entirely true here on LF/MF.

The DXE device looks interesting but I would point out two things. They say it will pass a 25 mW signal which is many dB above the safe maximum specified for some receivers I've seen, particularly SDRs. It is also rated 500 kHz and up which leaves open the question of what happens if you try to use it at 2200m.

I'm all set now. I will be posting a follow-up to this topic shortly.

73,
Paul

Morning Paul,

Couldn't you use the same technology you used to protect the Pre-amp in your EME Array?
Or I wonder about on of those DX Engeneering RX protectors.
