★The MAX7219 also allow the user to select code B decoding or no-decode for each digit..
★The MAX7219 is compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs..
★Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit..
★Only one external resistor is required to set the segment current for all LEDs. A convenient 3-wire serial interface connects to all common µPs. Individual digits may be addressed and updated without rewriting the entire display..
★The devices include a 150µA low-power shutdown mode, analog and digital brightness control, a scan limit register that allows the user to display from 1 to 8 digits, and a test mode that forces all LEDs on..

Five-digit frequency counter with large blue digits, two-digit channel display with larger blue digits. Large Galaxy meter with 4 scales: "S" Meter indicates up to 60 dB over S9. Modulation Percentage Scale for use on AM. Power Scale Calibrated for AM and SSB. SWR Scale.
The Galaxy StarLite faceplate features back lighting of the white faceplate lettering in blue or red color back lighting. All faceplate lettering is white during daylight. The picture shows how the color back lighting turns the lettering blue or red. Frequency and Channel LED digits are always blue - day or night.
Large, easy-to-read meter with scales for power output, modulation, SWR and incoming signal.
Variable power output control, variable talkback circuit with on/off switch, automatic SWR circuit and an SWR alert LED, Roger Beep with on/off switch.
Variable dimmer control with push switch to turn off the meter lamp, display digits and Star Lite back lighting, 3-position tone switch for receive, proprietary Galaxy Noise Filter (GNF) Circuit reduces noise to aid in the recovery of weak SSB signals.
