Your friends are probably concerned that you'll transmit into a very high SWR if you transmit when the switch is in position to switch the analyzer into the circuit. Transmitters do not like open or grounded antenna circuits at the output - they're the ultimate high SWR condition.
Of course, if you're careful it'll never happen (but never say "never", Hi) Even so, the K3 can handle it, but it's bad practice. A better approach would be a double pole switch that simultaneously switches the K3 from the tuner to a dummy load and the analyzer to the tuner. Then, should you accidentally transmit while the analyzer is in the circuit, the K3 will see a normal RF load on its output. Ron AC7AC -----Original Message----- Hello Wise and Powerful Reflector; I have a couple of doublets I feed with balanced line. The balanced line goes to a current balun and then a short coax run (5') to my tuner. After the tuner I have another short coax run (3') to a coax switch that places either my antenna analyzer or the rig in the system so I can tune the antenna. I've had it suggested to me that the coax switch places my precious K3 in danger. The fact that this arrangement has worked up until this point isn't reassuring. What say you all?
