    can the switch be used in reverse.? Example is 2 Transceivers and one antenna? I assume so but just want to check. On one radio will be in use at a time but I only use a single dipole

    I use several that way without any issue. More radios than antennas. Second page of their data sheet for the Alpha Delta 4B switch states it.

    The Instruction Sheet for the Delta 2-B and 4-B covers that.

    Yep. That's how I use them. Have two, back to back (front to front?) one switches between radios, and its output goes to another that switches between antennas. With the 4 position ones any of 4 radios can be connected to any of four antennas ( or a dummy).

    Yep. The documentation that comes with the switch says so.

    Nice shack! Like those racks. Are they standard 19" panel racks? If so, do you have a good source?

    They look to be 19" racks with shelf packages.

    Thanks. Yes they are standard server racks from Navepoint. I added attachment points at the rear of the shelves that hold the older rigs. Didn't want the 922 hanging over my head without them.
