Operation through the RRC-1258MKII System
When you press the POWER switch on the K3 or K3/0 front panel to turn the unit on 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 site K3. All the controls and menus at the control site K3 or K3/0
control the remote site K3, except for sending CW. Note that changing
CONFIG:SPKRS+PH menu only affects
the remote site K3. The K3/0 and K3/0-mini is designed to mute the speaker automatically when phones are
plugged in. If you do not get stereo reception on your phones when using a sub receiver, ensure you set dual-rx
on the remote site RRC-1258 unit to Yes (see pg 13).
Configuring CW

Sending CW
You must plug your paddle into the RRC-1258 unit PAD jack as shown on the setup cabling diagrams. CW
keying speed is then controlled by the CW knob on the RRC-1258. A local CW side tone is generated by the
control site RRC-1258 unit. Since the RRC unit generates a local CW side tone, turn the “Monitor Level” down
on the remote site K3 when in CW mode to eliminate the potential for a CW side tone “echo”.
Adjust CW Jitter for Internet Latency
Excessive variations (jitter) in the delay (latency) in the internet communications path between the control and
remote sites may cause dahs to be sent as dits and some dits not being sent at all. You can correct for this to
produce accurate CW transmission using “Keyer Settings” in the control site RRC-1258. The following settings
may be a good starting point for adjusting for CW jitter caused by internet latency.
 Lf delay ms: 100ms
 Key delay ms: 50ms
