Howdy K3' people: I use a sequencer which helps ensure that RF does not flow from the K3 before a sensitive LNA is switched out of the RF path.
This works if a foot-switch is pressed here. It works when the Tigertronics "SignaLink USB" closes the sequencer's PTT input. However, the K3's "XMIT" button will key the rig and I see no wy to have that action tell the Sequencer that it's internal PTT needs activation. This would need doing prior do RF flowing. If there was a way that a delay could be chosen/set to follow the pressing of XMIT button then I might try using the K3 PTT out or the XV144 Key-Out. I would like to think I will not press the K3 XMIT button but that "ain't gonna happen" as I am likely to use "XMIT" with a reduced output to tune an external 2m PA . Or, sometimes I am just stupid and press XMIT anyway ... wouldn't be nice to destroy an expensive LNA ..... especially in the middle of a QSO with a severely weak station. -- 73 KD7YZ Bob ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
