The BT board is installed inside the PTC-IIusb so that the antenna can radiate at the backplate of the PTC-IIusb.

The PTC-IIusb is now available with optional Bluetooth. Bluetooth is a low power high frequency (2.4 GHz) radio link which serves as a cable replacement for short distances.

The data stream signal of a USB interface is located in the middle of the shortwave bands. Therefore, the USB data signal cannot be separated from the shortwave signal being transmitted or received by simply filtering. Mutual interference is possible, especially where the antenna is located close to the modem/PC setup (ship borne installations). Mutual interference in this case means that the transmitted HF-signal can disturb the USB data stream between PC and modem, as well the USB data stream can disturb the radio reception of shortwaves.

Bluetooth can help solve this problem, as Bluetooth and shortwave radio signals don’t interfere with one another. Additionally, eliminating the USB cable connection, the danger of ground loops and parasitic currents distorting the radios signal modulation are removed, which will lead to a better transmission quality.

You can order the PTC-IIusb with Bluetooth option already installed, or you can get an existing PTC-IIusb extended for Bluetooth by an authorized dealer or by SCS. For the prices for both versions please refer to the price list or ask your dealer.
