I know that others have responded to your query, but allow me to make some additional points. 1. I presume that you purchased the remoterig from Elecraft and that you have the RemoteRig cables from Elecraft to connect the remoterig not only to the K3/0-mini but the remote rig to the K3. These cables provide the critical interconnects needed for the K3/0-mini to function properly. The K3/0-mini manual does a nice job of explaining how to make the proper connections. 2. I use a y-adapter to connect the remoterig PTT cable to the PTT port of the K3 so that the PTT switch I use at the K3 will still function. There is no problem having both PTTs connected at the same time. This will allow the K3 go to into transmit by command of the remoterig or by the handswitch at the shack. 3. I use a stereo y-adapter to connect the Remoterig Audio cable to the Speaker port of the K3 so that audio will be fed to both outputs. This setup does cause my external speakers at the station to change volume when remote operating as it also provides audio to the Remoterig. In other words, the AF volume on the K3/0-mini will control both audio outputs. Since I’m not at the station when operating remote and no one is around, having the speakers active doesn’t bother anyone. If the K3 is located where audio might bother others, then either turn off the speakers (if they’re powered) or install a cutoff switch/unplug the speaker(s). 4. Keep in mind that the K3/0-mini controls what the K3 is doing as the K3/0-mini front panel is duplicating what the K3 is showing on its panel. That is, as you increase audio on the K3, it is also potentially increasing audio of speakers at the shack. If you set a parameter on the K3/0-mini, it is displaying what the K3 front panel is showing as that adjustment is made. One area to note is how microphone management is done. The Remoterig uses the rear mic connector of the K3. Thus, on the K3/0-mini, you must use the K3 Menu to set the mic source to the rear connector. If the mic connected to the K3/0-mini needs bias, you set that through the remoterig configuration. In other words, mic selection through the K3 menu has nothing to do with the mic input of the K3/0-mini itself; rather it determines the mic input used by the K3 itself. Both the 8-pin connector on the front panel of the K3/0-mini and the side Mic connector are active. Thus, mic selection using the K3/0-mini does determine whether the mic input is from the Remoterig (rear mic) or from the K3 itself (front mic). 5. Management of the KAT500 and KPA500 can be done several different ways. Clearly, basic operation of both units will work the same as before if the appropriate cable connections are installed as described in the Elecraft manuals. One can use a remote connection to a PC in the shack and use the Elecraft utilities. I prefer to manage the KPA500 with the Remoterig RC-1216H which provides a web-based display of the KPA500 front panel and is connected to the amplifier through a RS-232 connection. This allows me to manage the amplifier with any PC, Mac, iOS device, etc. I have port forwarding set up at the station so that I can access the RC-1216H directly. As the RS-232 connection is attached to the RC-1216H, I cannot use the KPA500 utility from the shack computer. However, I don’t see that as a problem. The KAT500 can be managed using the PC in the shack and then remotely connecting to the shack computer to manage the KAT500 running on the shack computer. I manage the KAT500 one of two ways. I’ve installed a serial-to-ethernet converter (Lantronics) which allows me to directly connect to the KAT500 remotely and run the KAT500 utility on the PC where I am. Or, I can have the PC in the shack connect to that same serial-to-ethernet converter and run the KAT500 software on that machine. In this instance, I use VNC Connect to access the shack computer using any PC, Mac, iOS device, etc. Sidenote: If I didn’t have the RC-1216H, I’d probably be managing the KPA500 the same way. 6. Lastly, please keep in mind that if you’re intending to remotely operate from a significant distance from the shack, it is imperative that you test everything at the shack first. Setup the K3/0-mini and the Remoterig that goes with it on the LAN hosting the shack equipment and the Remoterig attached to the K3 and ensure that it works as intended. Ensure that you know that all connections are working as intended. With regard to cables going to to/from the Remoterig (both units), label each cable end. This will also ensure that you plug the correct cable into each socket the next time you setup at your remote location. At the station, having properly labeled cables will help keep track of what is plugged in where. Over time and presuming that you intend to remote operatel extensively, you may also want to consider at some point how best to remotely manage equipment at the shack. This includes, but is not limited to remotely powering and controlling the antenna rotor, powering down and restarting equipment, remotely rebooting your modem/router/PCs, etc. In my case, I’m over 1,200 miles from my remote site. Over the years I’ve made numerous enhancements at the shack in an effort to reduce ’single point’ failures and improve reliability. Given that it may be a month or more between visits to the shack, I’ve learned that most of the effort to create a remote capability is not how to make the initial connections between amateur equipment, but setting up processes to reset/reboot/power on-off a myriad of devices that help the amateur experience but also be able to do some basic ‘reset’ of infrastructure remotely. A hung device (such as an Antenna Genius) is best resolved by powering it down and then powering it back up. And if you’re in a lightning prone area (such as South Georgia or Florida), being able to remotely disconnect coax connections (such as using a Paradan Antenna Disconnect) or even removing power from the K3 (e.g. shutdown the power supply) and other equipment may also be desired. In my case, I have the ability to remotely to power on/off the RRC-1226MKII at the shack, the KAT500, and the Power Supply that powers the K3.
