Constructing an interface box allows you to connect the radio to a PC for digital modes like Modern Microphone Adapters:
To enable continuous transmit across the entire frequency range (1.6 MHz to 24 MHz), remove specific diodes based on your exact sub-model revision. icom m700 mods
Modifying electronic equipment requires soldering skills, knowledge of high-voltage circuits (the M700 has lethal voltages inside), and proper test equipment. The author assumes no liability for damage to your radio, your vessel, or your person. Proceed at your own risk. Constructing an interface box allows you to connect
The most advanced model in the lineup. It offers wideband general-coverage receive (0.5–29.9999 MHz), higher transmit power (150W PEP), and often comes factory-equipped for ham band operation without hardware modifications. Proceed at your own risk
The M700PRO offers two distinct methods for power adjustment. The first involves entering the radio's hidden configuration mode by pressing specific key combinations during power-up. Once inside, output power can be adjusted through on-screen menu options.
Eli wasn't a spy. He wasn’t a prepper or a pirate. He was a late-night AM DXer, a hunter of ghosts in the static. He’d bought the M700 at a maritime flea market in Rotterdam for two hundred euros, its grey paint chipped, the "CH" button worn smooth. The seller, a grizzled tugboat captain, had called it "indestructible, and just as deaf."
Marine radios are type-accepted for specific maritime bands (Tx 1.6–27.5 MHz). They are not legally permitted to transmit on Amateur Radio bands (160m through 10m). However, the hardware inside the M-700 is fully capable of operating across a broad spectrum of HF frequencies.
