If you haveimplemented QSK then you don't need to purchase a new relay for this mod. I used original PTT relay since it's no longer used after adding QSK. I have mounted this relay on a piece of perfboard. Resistor is in series with this 110V DC relay and is 3k3 3W. With original HV capacitors it gives about 1.5 sec delay. Very useful mod.
