I wouldn't trust an RF-sensed switch to do the job (have never seen one
anyway). The antenna jack on the rig that is NOT to be used would have to be grounded first before allowing the primary rig to transmit. A bit of a dilemma. You can use a manual coax switch (which grounds the unselected outputs), but even then quite a bit of signal is coupled to the transceiver who's connection is grounded. I tested this setup on HF, bringing the power up slowly on the selected rig and tuning the unselected rig to the same frequency. On 10 meters, the signal present on the unselected rig's input was enough to cause a 45 dB over S9 signal. Not enough to damage the frontend in this case, but you'd need to test the switch you're planning to use to see what results you get. K8AC "Chuck W." wrote in message oups.com... I'm wondering what is the best practice for connecting two transceivers to a single transmission line/antenna, or even if it is advisable to do? What would be great is if there was a switch that would share the line between the 2 transceivers when no outgoing RF is present, and switch everything to one rig when RF is sensed. However, I haven't seen a product that does this! thanks for any thoughts, 73, Chuck KB5GC |
