The RC50-C is HF email software delivering fast, error free email over HF radio at adaptive data rates up to 19200 bit/s, with STANAG 5066 interoperability and AES-256 encryption.
Remote teams still need email when internet and mobile networks are unavailable. Running on a standard Windows PC with Codan HF transceivers and RM50 data modems, the RC50-C software works in the background through a standard email client. Adaptive data rates respond to channel conditions, using the fastest reliable rate available and reaching up to 19200 bit/s with an ISB-capable transceiver.
HF email has to work across mixed networks and allied systems. STANAG 5066 support ensures interoperability with other manufacturers’ systems, while POP3 and SMTP compatibility keeps operation familiar. Enhanced CALM and ALE linking help select the best channel for each session, and gateway mode can connect remote HF stations to wider Intranet, WAN, or internet email services.
Email sent over HF needs strong protection. Over-the-air transmissions can be secured with AES-256 encryption, with support for third-party email encryption software for full end-to-end protection. The software is lightweight, requiring modest PC hardware while supporting reliable, error-free email in remote and contested communications environments.
Adaptive data rates up to 19200 bit/s with an ISB capable transceiver, controlled by BER measurements for the fastest reliable rate.
STANAG 5066 V1.2 Annex F.12 Compressed File Transport Protocol ensures interoperability with other manufacturers' systems.
Over-the-air transmissions encrypted with AES-256, plus support for third party software for full end-to-end encryption.
Operated through a standard POP3 email client running in the background on a Windows PC over a single USB port.
Enhanced CALM and ALE linking selects the best available channel for each data session, simplifying operation.
Configurable as a gateway to a wider Intranet or WAN for a fully integrated field email service.
Supports MIL-STD-188-110A and 110B, STANAG 4539, 4285, 4415, and 4529 waveforms.
