Re: Antenna Routing

[m5kvk]

Thanks, Mike
It's a K3S, so it has the upgraded KSYN3As

    Did I read at some stage that you do not have the internal ATU? That
    being so you will not have selectable ANT 1 or ANT 2. That being the
    case you will only have AN1 1 (the main RX/TX antenna) or the Aux RF
    antenna available to you for the Sub RX. You can forget all the ANT 1 or
    ANT 2 stuff because you don't have an ANT 2 available.

    With the SUB RX activated (tap SUB) and hold B SET which will then be
    displayed on the main display tapping the ANT button will toggle between
    Main and AUX. If you want the sub RX to listen on the same antenna as
    the main RX this should be set to MAIN.

    For now forget RX ANT, just make sure the RX indicator is not showing on
    the main display (immediately under the third digit of the main
    frequency display).

    This is the simple starting point. We are looking simply at Fig 1.

    Is the K3 upgraded to the new synths? Probably not, however, old or new
    they both, and you need two, have to be the same, not mixed.

    How are we doing?

In either case, the ANT 1 - 2 icons will show which KAT3 antenna is available for use by the subreceiver. If sharing, it will be the same antenna in use by the main receiver. If not sharing, it will be the non-transmit antenna.
