Setting up most any digital interface for use with the K2 is a similar task - that is if you break it down into 3 pieces of communication with the K2. The remainder is specific to getting the jumpers set correctly in the interface box to direct the signals to the proper wires in the K2 to interface box cable(s).
The first consideration is audio input to the K2 - this is normally straightforward, just use the microphone AF pin for the path and set the level using a trimmer pot in the interface box. The second is the audio output from the K2. The simple method is to use the K2 headphone (or external speaker) audio output, but that output will vary with the setting of the AF Gain control (just set it at something like the 10 o'clock position). For a more advanced solution, look at the W3FPR Fixed Audio Output for the K2 on my website www.w3fpr.com and also at the updated board layout for the same circuit on Tom Hammond's website www.n0ss.net. No boards are available now, but the circuit is easy enough to wire on a piece of perfboard. The 3rd (and last) element is how to activate transmit. That is normally done with a PTT output from the interface box. That can be connected to the K2 at the microphone jack PTT pin, or the dot contact of the key jack. If you are using Ham Radio Deluxe (or another application that can set transmit using a CAT command to the K2), you can eliminate the PTT input to the K2 and simply connect to the KIO2 (if that option is installed). These are the normal ways an interface box is connected to the K2. I have not been specific about your Rigblaster, but if you want to understand a bit about "which you are connecting to what", study my notes above and then relate them to your particular interface box instructions. 73, Don W3FPR On 10/31/2010 1:42 PM, [email protected] wrote: > > Folks, > > Does anyone have experience installing a Rigblaster Plus II for use with a > K2?
