Description
P4dragon DR-7800
Our HF modem P4dragon DR-7800 is the uncompromising advancement of the legendary PTC-II which is designed for professional deployment and for the ambitious amateur radio operator. DR-7800 is software-compatible with PTC-II which means that one may continue to use the existing software, such as AirMail, RMS Express, Alpha, etc., for PACTOR as well. Due to the pin compatibility of the radio equipment ports a change-over from the well-tried PTC-II technology to the innovative P4dragon technology is made convenient: re-plug, switch on and enjoy the higher speed and robustness with the PACTOR connectivity! USB Connection for PC is standard.
P4dragon DR-7803 Includes built-in Bluetooth connectivity so you can connect without the USB Cable. Bluetooth eliminates RF interference commonly seen with the USB connection, protects from galvanic corrosion, and allows you to access your HF Email from anywhere within Bluetooth radio range of the Pactor modem.
Embedded Linux / Ethernet Host available as an option for 7800 or 7803 as well!
The elegant design and the excellently readable and informative OLED display including the simple upgrade facility (updates free of charge!) round off the concept of the absolutely latest shortwave modem from the house of SCS.
DR-7800 can be ideally used for HF email, for example, over the Winlink network. Externally, it stands out due to its high-resolution OLED display which, among other things, can be configured for waterfall and spectral views. Thanks to its reliability and low power consumption of 3 W, the new modem is also well-suited for distress radio communications and other applications under severe conditions.
