    Use Quantar RSS and a service monitor. Same as a radio.

    Quantar RSS is available in the file download section of our forum.

    I will post a screen shot when I get home. Perhaps 90 minutes or so.

    P.s. if you have the high stability oscillator option installed, there is no frequency adjustment. It's all auto.

    This is the alignment screen. Notice I have the Internal UHSO option installed, so I can't make adjustments on mine. But if this option is not installed in a machine, the adjustment fields are adjustable.

    Is this Reference osc alignment also adjust the Receiver ? does it serve for both receiver and transmitter ?
    I thought that on a Repeater there will be two adjustments one for receiver frequency and one for transmitter
    Thanks forward
    ill check this and see if it adjust the receiver frequency ...

    Hi

    The warp adjustment affects both the RX and TX.

    The Quantar isn't a crystal receiver with a trimmer for fine tuning

    Kind of - you are actually trimming the VCO with a variable capacitor in the form of a Varactor Diode. The varactor acts like a variable cap based on the steering voltage applied to it - but it capacitivley "warps" an oscillator frequency just like the old trimmer caps. The oscillator it warps is the master oscillator for both the TX and RX VCO's, so it affects both frequencies.
