CW Morse Code Straight Key, Twin-T Sidetone Oscillator & 500m Twisted-Pair Field Telegraph Builder's Kit (OGA-MAK-104)
Get through on 5W HF when voice signals drown in static (+13dB CW advantage)—or run a zero-RF 500m wired field telegraph between outbuildings.
UK Blackout & Field Application
Continuous Wave (CW) Morse code requires the simplest transmitter circuit on earth and penetrates ionospheric noise 13dB deeper than SSB voice. Better still, stringing the included 500m twisted-pair field wire between a house, barn, or observation post creates a completely unjammable, zero-RF point-to-point telegraph.
Engineered for Both across Great Britain. In a prolonged utility outage, CW Morse Code Straight Key, Twin-T Sidetone Oscillator & 500m Twisted-Pair Field Telegraph Builder's Kit provides dependable off-grid capability backed by our UK warehouse support and plain-English commissioning documentation. Every unit is inspected prior to dispatch with an estimated UK delivery window of 48h.
