Re: Repeater hang time/tail circuit
|
I did one years ago with a 555 driving a 4093 Schmidt trigger with a RC circuit to handle hang time...it's easy .. I don't have the schematic here with me right now but I can post it later?

Hi everyone.
I built myself a repeater with a pair of Kenwood radios, ESP32 based and fully functional (automated beacon, auto/manual mode, screen ...). Although repeater tail is implemented by software (which for me was the fastest and easiest) I would like to experiment in implementing it by hardware.
I saw in the past that using a 555 working as monostable would be a neat, easy solution with adjustable components. I looked through the net but couldn't find any circuit used specfically in ham radio repeaters. Would anyone share a circuit like that explaining its connections and so?
?
Thank you in advance for your time!
