I would like to be able to key an external amp with my K2/100. I see on the
web site a circuit and a reference to the AMPMODKIT to purchase the parts. There I see a note that the parts are included in the KPA100 kit. However, I don't remember building this and don't see a connection point on the back of the /100 cabinet. Did I miss something? 73 Tom K6CT _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

Hi Tom. If you already have the KPA100, look on the rear panel and you will
see an RCA jack marked "PA KEY OUT" between the ground connection and the power connector - this will allow you to key your external amplifier directly - but only if your amplifier has a positive voltage for its keying line. If your amplifier uses a negative voltage keying circuit (like the Collins 30L-1 and some others) you will need to construct an external circuit to key the amp. 73 --don n4hh K2/100 #2028 ----- Original Message ----- From: "TMorton" <[hidden email]> To: "Elecraft" <[hidden email]> Sent: Wednesday, December 01, 2004 8:11 AM Subject: [Elecraft] K2/100 amp keying? > I would like to be able to key an external amp with my K2/100.

Hi,
What is the limit on voltage and current of the PA Key Out? I am getting ready to hook up a linear to my K2/100. I do have an external relay if needed.

Chas,
The KPA100 specs state that the PA Keying Output will sink up to 1 Amp and handle up to 200 volts. This is only for positive voltage sources (it will not function with negative voltages), and it behaves similar to a contact closure to ground. 73, Don W3FPR ----- Original Message ----- > > What is the limit on voltage and current of the PA Key Out?
