[1000mp] RX Ant during TX

Hello Csaba,

I believe you are correct.

However, I have always used a KD9SV front end protector relay accessory to
keep RX signals out of the transceiver when transmitting and listening on
a second antenna.

They are available from DX Engineering in Ohio, USA.  Originally this was
published in a magazine years ago.

It has a small high speed relay that opens or shorts to ground when the tx
ground contact is closed on any transceiver.

Good luck,  73,  George, K8GG
