Hi Chris,Use a relay, switched by a FET which is switched by a RS232 line. Then you can toggle the state by using SpecLab, each 2 minutes automatically, even at 0x:55, ie.between the sequences, where the TX is off. For LF you can use a normal relay, it does not need to be a coax relay. Consider to detune the unused RX antenna, i.e. avoid coupling. 73, Stefan Am 20.03.2019 12:27, schrieb Chris Wilson: Hello LF'ers, Looking for ideas re automatically swapping two RX antennas over to one receiver timed to WSPR or other timed digital modes to compare performance, Anyone got any input please? Thanks. |
