re: Cheap Protection for your Downconverter



What I have not heard suggested is to simply wire up a coaxial relay
between the sequencer/bias T and the downconvertor. If your radio
provides sequenced preamp voltage bias, you would be ready to go. Simply
use the bias to activate the relay when receiving. During TX, when the
voltage is off, the relay could dump the TX into your 2 meter antenna or
a dummy load. Turning the bias off and on would allow you to select 2
meters transceive or S band RX.
