    Hi Tim,
    I have been un-successful in getting this delay line to work with both the old version pf psdr as well as the latest version from Darrin. I completely un-installed both versions then installed the old version and tried it and then installed Darrin's version but still no go. Its not a serios issue as I can work around it with ptt circuits in the projects. Darrin said that his only worked when he ticked the button a couple of times, but not for me.

    Can you send me a screenshot of the delay setting?  I want to see the entire Setup panel where you have the value set.

    You have it set up correctly.

    I doubt that you could determine a 1ms delay without using a scope.

    So how this works is if you set the delay, once you assert PTT, the radio will key the amp or whatever device is connected to the TX RELAY immediately and will delay sending RF by the time value selected.  I just tested it with a 999ms delay and verified that RF output was delayed by approximately a second.
