The M700 uses a Phase-Locked Loop (PLL) with programmable dividers. Jumpers on the main PLL board (often labeled the "PLL Unit" or "Frequency Unit") set the frequency limits. By changing diode or jumper configurations, you override the marine band limits. icom m700 mods
Since the M700 uses a non-standard microphone connector (often 7 or 8-pin), users frequently build interface boxes. These boxes bridge the radio’s Mic/PTT and Speaker outputs to a Pactor modem or a computer sound card for digital modes like FT8 or JS8Call.
