Introduction On behalf of our entire design team, we’d like to thank you for choosing the Elecraft K3 Remote system. The K3/0, or a regular a K3 in ‘terminal mode’, provides a unique real time remote control experience for operating a K3 located in the next room, or across the country. The latest K3 and K3/0 firmware supports a compact remote control serial protocol that provides a 100% recreation of the remote K3 on the controlling K3.
What You Will Need To operate a K3 remotely through your local area network (LAN) without communicating over the internet, you need: Suitable cables to connect the RRC-1258 units to your router. A personal computer to configure the RRC-1258 units. To operate a K3 remotely through an internet connection, in addition to the above you will need the following. See Finding Your Network Information below if you need help determining I.
Setup Guide If you want the units to communicate between your local and remote systems over the internet, you will need to configure your network routers and program the RR-1256 units as follows. You should not need to program the units if you have both of them connected to the same local area network (LAN) such as a home network that functions whether or not you have internet access.
2. Connect your computer and power to one of the RR-1256 units (see Figure 1). Figure 1 3. Launch the Microbit Setup Manager you installed. You should see a window similar to Figure 2 reporting that your computer is communicating with the RR-1256 unit and that it has successfully retrieved the firmware (FW) and software version (SW).
4. Click on the Setup tab to open the window shown in Figure 3. Figure 3 5. Click on the Get button to open the Setup Info window (Figure 4), check and correct the following entries as needed: I.P. address: This address should match those shown on pg 5 for the RR-1256 unit you are programming. If needed, you can enter a new I.P. address (for example, if you already have another device on your LAN using the address shown) Gateway: This must match the I.P.
7. Disconnect the USB cable between and connect both the RR-1256 Local (Control) unit with the CW knob and the computer to your LAN (Figure 5). Note that the PWR light on the RR-1256 unit’s front panel stops blinking and remains on, indicating communications with the router. If it continues to blink, check to ensure the cable connectors are fully inserted and that you have a good cable. You must have a steady green PWR light to proceed. Figure 5 8. Open your computer browser and enter the I.P.
. Check or enter the following data in the Radio Settings window. Note that some are selected using dropdown menus: Program Mode 14 Elecraft K3-twin Sip Password (Optional: No entry required) Sip Contact (Enter the Public I.P. of your remote router.
Configuring Your Network Router The network router used at the remote location must be configured for port forwarding as follows. No configuration is required at the router used at the control location. 1. With a computer connected to the remote LAN router, open the browser and enter the router’s I.P. address to open the router’s configuration page (Figure 7). Various makes of routers will show different pages. The examples here show the Linksys router’s configuration pages.
2. Locate the port forwarding page. On the Linksys router, this is under Applications and Gaming. With other routers, likely it will be under a similar heading. Enter the following data as shown in Figure 8. Be sure to check Enable for each entry, and then click on Save Settings to save the changes. Application Start End Protocol IP Address RRIG_radio 12000 12000 Both (UDP and TCP) 192.168.1.170 RRIG_radio 11000 11000 Both (UDP and TCP) 192.168.1.
Remote Site Setup 1. Apply power to the K3 and confirm that it has firmware version 4.47 or later installed. If not, update the firmware as described in the K3 Owner’s manual. 2. Set the K3 for rear panel mic input and no bias (see the K3 Owner’s manual for details), regardless of the type of mic used. The RRC-1256 units automatically supply bias. 3. Cable the remote K3 to the RR1256 unit as shown in Figure 9 using the RRMTCBL cable set.
Local Site Setup Using a K3/0 Figure 10 13
Local Site Setup using a K3 (K3/10 or K3/100) The K3 must have firmware version 4.47 or later installed.
Operation When you press the POWER switch on the K3 or K3/0 front panel, you should hear a beep and see frequency data displayed on the LCD, indicating that your local equipment is communicating with the K3 at the remote site. Operation is identical to sitting at the remote K3. All the controls and menus at the local K3 or K3/0 control the remote K3, except for sending CW. Note that changing CONFIG:SPKRS+PH menu only affects the remote K3.
