  2. Independent audio LEVEL  for TX and RX.

  3. Full galvanic isolation between PC and Transceiver, as well as full RF shielding.

  4. Power supply 5V from USB B (PC).

  5. 5pin Din connector for input and output controls [AUDIO IN, AUDIO OUT, PTT, AF UNLOCKED (cos), XMTR's GND].

  6. Adjustment for each type of transceiver. (Base, Mobile, Portable).

  7. USB Type B output for PC connection. 

  8. Two 3.5 mm inputs for audio in and audio out of a separate external audio card. (not included).

  9. Dual PTT, to and from the PC program (via UART chip and microcontroller). Using FTDI* or Prolific. *, **

  10. Protection against RF and for low power transceivers.

  11. Two-level board with metallic holes and vias for integrating upper and lower surface ground grids.

  12. Independent indications for power on, RX-TX and lock.

  13. Added ground point on the back face.

  14. Pass band RX audio filter 250Hz-3.2kHz

For FRN, Echolink, Ham Radio Deluxe, cw
