Hi The KIO2 is required in the QRP K2 to supply the interface signals for the KPA100. This is the auxbus, 12 volt switched, 8R signals. It is possible to build a cable from the control board to a 9 pin connector to provide these signals but you will need to duplicate the RF bypassing used on the KIO2. The best solution is to just add the KIO2 to the K2 QRP top to provide the signals.
All you need to connect the two boxes is a 9 pin D connector cable with the bottom 4 pins connected and a ground to pin 1. A BNC to BNC for the RF and a power cable for the K2 and KPA100. If you do not have the KAT100 installed in the box with the KPA100 then you will need to drill a hole in the lower back panel for a chassis mount BNC connector and provide a connector inside for the KPA100 RF connector. If you have the KAT100-2 then the connectors are included on the KAT100 board. If you have the KAT100 then you will also need a short PL259 to PL259 cable to connect the KPA100 to the KAT100 Don Brown ----- Original Message ----- From: J F<mailto:[EMAIL PROTECTED]> To: [email protected]<mailto:[email protected]> Sent: Wednesday, September 22, 2004 11:48 AM Subject: [Elecraft] remote KPA100 OK, this may be a silly question but... Why do I need a KIO to run the KPA100 remotely? In my case, I just want to have the PA in a seperate enclosure to keep it in a better ventilated area of my congestion (maybe 2 or 3 feet away from the K2). Is this too long of a run for the I/O cable or RF?
