KD-780C emergency communication interconnection terminal

PTC-IEx modem is a data communication device connected between a computer and a shortwave radio station. This data transmission device can be paired with Curton NGT SR, Polaroid 2050, IC-M700PRO radio stations, and most shortwave radio stations in the world, with superior performance. It can reach 5.2Kbps at high speeds and has extremely low speed function. It can still maintain the connection to transmit data even when the signal-to-noise ratio is -20dB (that is, it can transmit data even when someone is just hearing someone talking in the short wave signal range), and is one of the advanced shortwave data communication devices in the world.

    DESCRIPTION

    PTC-IEx modem is a data communication device connected between a computer and a shortwave radio station. This data transmission device can be paired with Curton NGT SR, Polaroid 2050, IC-M700PRO radio stations, and most shortwave radio stations in the world, with superior performance. It can reach 5.2Kbps at high speeds and has extremely low speed function. It can still maintain the connection to transmit data even when the signal-to-noise ratio is -20dB (that is, it can transmit data even when someone is just hearing someone talking in the short wave signal range), and is one of the advanced shortwave data communication devices in the world.

     

    Function

    1.PTC-IEx modem is an economical multimodal data interface connected between a computer and a shortwave radio station. PTC-IEx can provide robust PACTOR-I and PACTOR-II digital connections (supports PACTOR-III and requires additional cost to purchase certificates). PTC-IEx can still maintain connection transmission data at a signal-to-noise ratio of -18dB (turning on the ROBUST mode can operate at -20dB). That means the data is transmitted in an absolutely inaudible signal. PTC-IEx is a cost-effective option that does not sacrifice communication performance to reduce costs.

    2. The high-performance Motorola 68 series CPU and high-speed DSP digital signal processing system provide strong power to PTC-IIex, and PACTOR's superior technology creates PTC-IIex's extraordinary performance in the short wave band. The PACKET MODEM (AX.25) with a built-in 19200 baud rate provides high-speed data transmission for VHF/UHF.
