Key shaping circuit PA) 3 Switchable Analog Modulators Independent of Pre Receiver 0db, -13db, -20db, -33db, -53db, -60db, -73db Mds Receiver Noise Level: -135dbm (200hz bw) at 28mhz Pre Receiver Selectivity: Steep Frequency Tuning -45db, Decade Roll Off +, - 2khz Blocking Dynamic Range: 123db at 20khz Offset, 78db at 2khz Offset CW Decoder, Straight or Inhibit Grid -a or b Keying -Vfo a or b + Rit and Crossover, and switching of the corresponding relays with filters via i2c-Cat support (TS480 subset) allows streaming of voice, keystrokes and display text over CAT. This is probably the most economical and easy to build standalone sdr or ssb transceiver. Greater simplicity simplifies the original qcx circuitry (i.e., 50% fewer mounting components, 50% fewer mounting components, no complex transformer windings, no pairing procedures), greater versatility Port Introduction: Charging: Built in charging port for lithium batteries, only use the supplied charger Prohibit the use of other chargers Switch: Off, Bat: Built In Battery Power, 13.8: External Power Supply DC13.8V, 3a: External Power Connector.
