K3KU Keying Circuit

[ct-user@sttng.mlo.dec.com (Eric M. Guzman )]

Hi All.

        I'm trying to make the K3KU keying circuit from the page 19
        of the CT User's Manual. The manual says the transistors are 
        1 PNP & 1 NPN but it doesn't say which I can use.

        From the previous circuit I guess I can use the 2N4401 for the NPN
        but which for the PNP? ( MPS2709? )

        Does any one here can suggest me a pair of transistors that work 
        for this ckt?
Thanks.
