FRONT PANELS7Ten Segment LED BargraphThe bargraph provides a visual indication of the received HF signal. The end segments, labeledMARK and SPACE, blink alternately on a properly tuned RTTY/ASCII/AMTOR or Packet signal. InCW Mode the left end (MARK) of the bargraph illuminates when no signal is present and the rightend (SPACE) lights when a signal is detected. In addition, when your PTT line is being keyed totransmit on the HF port, the LED bargraph will be blanked out. The bargraph may be used to tuneWEFAX if the audio from the WEFAX signal is connected to the HF radio port as well as the VHFport. Between picture transmissions, most WEFAX stations transmit a SPACE signal.KPC-4The front panel has a power switch and nine LEDs. There are eight LEDs used as operating statusindicators and one for power. The front panel is divided into four sections, each section containingtwo operating status LEDs. Each section is separated by a white color bar. Each LED has the func-tion indicated below:PORT 1XMIT – This LED will illuminate when the KPC-4 is keying the PTT line of your radio attached toradio Port 1.RCV – This LED will illuminate when you are receiving data from your radio attached to radioPort 1.STREAMCON – This LED will illuminate when you have a Packet connection on the current stream. Thecurrent stream is the stream to which the I/O is directed. (See STREAMSW in the Commands Man-ual.)STA – This LED will illuminate when you have unacknowledged packets on the current stream.PORT 2XMIT – This LED will illuminate when the KPC-4 is keying the PTT line of your radio attached toradio Port 2.RCV – This LED will illuminate when you are receiving data from your radio attached to radioPort 2.
