Thanks to those who have responded already. I was hoping for some
elegant solution I had not thought of, but so far nothing has come to light. Also I was hoping there would be some way to implement this wihthout relays.... but maybe not. Regarding the comment about breaking out the Rx line to a separate output... that might be possible but its solid state switching and would be somewhat tricky to implement right after this solid state PA module output. One reason I hate the thought of adding antenna relays to switch the Rx around the isolator is that this is a busy packet node and I don't like the reliability issues a couple of added relays might add to a presently solid state switched radio.. . although I could do this if forced to. Another option is to buy a second radio, and use it for the receive channel. Your existing transceiver would be used solely as a transmitter, and could thus be hard-wired to an isolator. You'd need to run the receiver on a different antenna, or have some form of switchable protection circuit to keep it from having its brains blown out by the transmitter. -- Dave Platt AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
