Good morning community,
Rig Flex 5000a with 2nd receiver.
I was wondering how to keep safe 2nd receiver when you have 2 antennas on your roof top working same band, one antenna on 1st receiver, the other one on 2nd receiver.
Use case:
Working with diversity reception, and transmitting from one antenna in this configuration.

I'll get the radio in a few days and i'm trying to figure out how to work properly with multiple antennas.
Thanks in advance.
Matteo.

    ok sounds rather obvious..dual antennas..receivers have to be guarded by hw or by appropriate band gap.

    True, doc is 6000 specific, but I was hoping the calculations would show where you are and suggest a way forward. We used it at field day last year.

      Hello All,  The Flex 5000 with the later 34x RFIO board has a setting in "Settings, General, RX2" called "Disconnect RX2 RF input on TX". It opens a relay during TX. Been running 2 antennas (for diversity) and legal limit this way for years with no problem. Not sure if the 6xxx series supports this. Great radio...

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
