Hi all

I need to make my GM-300 still ON in PTT after i left the MIC for only 1 second,because i made a repeater with 2 GM-300,soo i want to listen the reapeter,the PTT is to fast now,when you left the PTT the repeater leftit it too!,,i hope i made me understand! ...there´s anyway to do it ???

Thanks

Depending on the interface between the two radios, you can add PTT delay following the directions in Nand's circuit here:

Next to the last paragraph from the bottom gives details on hangtime.

well..mabe feeting a capacitor 2.2 in the cable i m using to join both GM-300 will make it ,,don´t?

Alredy tryed,,with a 2.2nf capacitor and a 1 khoms resistorthe variable resistor is alredy in the repeater cable!,,it its the same,,the PTT doesn´t wait nothing
...any opinion ?

Hi ,, aftrer many time i did it, using a 16v 2,2 capacitor, just must be solded in the rite conections
..and it makes very good efect on PTT

So you built your own repeater hang timer? Good job. (clapping hands)

yes i did, on the little bords of the cable RX to TX
