[Elecraft] driving external PA with K2

[G3VVT at aol.com]

Within the Elecraft application notes there are details of a  partial mod kit 
available for an external PTT feed:  http://www.elecraf
t.com/Apps/Amp_keying_ckt.htm 
 
This uses a 2N70000 and a 2N2222 transistor plus two resistors, and two  
connectors mounted on a perf board pcb. The transistors are  available in the UK 
though having problems finding the correct mating 8 pin  and 2 pin connectors 
here. Elecraft can supply a partial kit listed  at US$5 on the Elecraft 
website. This includes the transistors,  resistors and the 8 pin connectors. You have 
to provide the perf board, 2 pin  connectors and an external phono or 
whatever connector you decide to  use. I intend using this mod to hard key my 
Spectrum TRC4-10iL 4m transverter  which at present is working on RF keying. The PTT 
mod plugs in at the rear of  the K2 RF board at J13 location (if available)
