Hi Gary, [up on my soap box] The original ACC Repeater controllers had the... best kerchunk software. I tried for years to nag a few controller mfgrs to include the original ACC style kerchunk filter option and they all seem to miss the point and built the classic delayed tx mess.
Some day I'll nag Ken into thinking about trying the original ACC kerchunk feature into his rc210. [off the soap box] Anyway... to answer your question. It wouldn't be hard to make a delay trigger cor circuit using a simple 555 timer or a much better circuit with the dual 556 timer chip. Let's see what others have to offer up first and then we can throw out some circuit ideas. cheers, skipp > "Gary" <[EMAIL PROTECTED]> wrote: > > We have a 440 repeater with a Six meter remote base setup.
