P4dragon Firmware Version 2.1 with Robust Packet Radio

 DR-7800 with Firmware 2.0

From now on, the new firmware 2.1 for the well known SCS P4dragon modems is available. The firmware offers Robust Packet Radio (RPR) as an additional waveform for Packet Radio. RPR and PACTOR can also be operated “in parallel” via a single physical modem port. This is mainly relevant for common “stand-by” operation.

Also the new firmware offers the possibility to connect a secondary modem (e.g. a PC with a sound card or a MIL-STD modem etc.) to a DR-7800 via the AUX port. The secondary modem and the DR-7800 (e.g. PACTOR and RPR) use a single common transceiver which is connected to the MAIN port of the DR-7800.

Several other improvements and bug fixes round up the new Firmware. The update is free and available for download on the Internet.
