HF E-mail System SEICAM 2020E
Features Overview
• Interoperability: The Hagenuk HF e-mail system SEICAM 2020E is more than a standalone system.
SEICAM 2020E is an optional part of Equipped with the HF modem MDM 3000 E, SEICAM 2020E can use existing HF radio

maximum performance SEICAM 2020E uses proven military standard waveforms.
